  In the present paper, we revise the taxonomy of the Auriculariales having pedunculate (stalked) basidia. In total, sixteen new species from Europe, East Asia, North and South America, and tropical Africa are described. They are classified among the genera Hydrophana , Mycostilla , Myxarium , Protoacia , Protohydnum , and Protomerulius . In addition, the generic affiliation of eleven extant species is re-established based on phylogenetic and/or morphological evidence. A new genus, Elmericium , is introduced to accommodate a crust-like fungus, E. alabastrinum , from East Asia; phylogenetic data place it in the vicinity of the anatomically similar poroid genera Elmerina and Protodaedalea (Auriculariaceae). The generic description of Protohydnum is amended; in its current scope, the genus encompasses several species formerly assigned to Bourdotia , Ductifera , and Exidiopsis . Available environmental data point to a wider distribution of some Protomerulius spp. and greater species diversity in the genus than currently surmised from physical fungal samples.

  Corticium ochraceofulvum and Corticium subseriale , two taxa with narrowly fusoid leptocystidia currently placed in Phlebia , are studied by morphology and nuclear rDNA sequences. Phylogenetic analyses show that the two species belong in Phanerochaete , despite having constantly clamped hyphae. Study of the type of Xerocarpus cacao shows that it is an older name for Corticium subseriale . The type of Phanerochaete calotricha is studied and material corresponding to the type sequenced. Specimens identified as Phanerochaete calotricha but differing genetically are described as Phanerochaete volubilis . Phanerochaete avellanea and P. ericina are confirmed as members of Phanerochaete based on nrDNA sequences and study of type material. Sequences from North America published as Phanerochaete ericina belong to a different species. Odontia rufobrunnea is identified as an earlier name for Phanerochaete aculeata . Thelephora amphibolia is identified as an earlier name for Phanerochaete cumulodentata . Phanericium is introduced for Corticium tuberculatum and related species, and a new species, Phanericium gemellum , is described. The new combinations Phanericium americanum , P. rodriguezarmasiae , P. subglobisporum , and P. taiwanense are proposed. Corticium cremeo-ochraceum , Corticium joseferreirae , and Phanerochaete pallida are confirmed as distinct species and transferred to Phanerochaetella . An ITS sequence of Phanerochaetella joseferreirae from the type locality is provided and the identity of Corticium queletii is discussed. Two ITS sequences of Phanerochaetella exilis from the vicinity of the type locality are presented. An earlier published sequence of Phanerochaetella exilis is considered to represent an unknown species.

  Piloderma constitutes a small genus of soft, corticioid, ectomycorrhizal, widely distributed and mostly very common species. Microscopically, its members have traditionally been recognised by their simple-septate hyphae and by their small, thick-walled, colourless to pale yellow spores. We describe five new species from northern Europe based on molecular and morphological data: P. frondosum sp. nov., P. fugax sp. nov., P. lamprolithum sp. nov., P. luminosum sp. nov. and P. mirabile sp. nov. All the new species, except P. luminosum seem to be more or less rare. Piloderma fugax has a strong preference for old-growth forest – a lifestyle seemingly deviating from the rest of the genus. Piloderma mirabile is a sister species to P. sphaerosporum and the first known species with clamped hyphae. Piloderma lamprolithum is closely related to P. exiguum and distinguished by its large encrusting crystals. Piloderma luminosum is very closely related to, and morphologically semicryptic with, P. byssinum. To clarify its distinction from P. byssinum, an epitype is designated for the latter. Piloderma frondosum also belongs to the P. byssinum cluster and is distinguished by its association to broadleaved trees. An updated key to all Piloderma species is provided.

  Several species of wood-inhabiting resupinate basidiomycetes are reclassified following examination of type material and sequencing of recent collections. Grandinia ocellata is considered the correct name for Phlebia livida subsp. tuberculata and transferred to Mycoacia. Peniophora avellanea is an older name for Phlebia margaritae and the species moved into Lopharia. Radulum pendulum is identified as the oldest name for the species most commonly called Phlebia albida. Grandinia tuberculata, type species for Stereophlebia, is accepted as a synonym to Radulum pendulum and the combination Stereophlebia pendula introduced. Phlebia canadensis is accepted as an older name for Quasiphlebia densa and the combination Quasiphlebia canadensis proposed. Other new combinations proposed are Cytidiella pallidolivens, Hydnophlebia flavicans, Hyphodermella pallidovirens, Meruliopsis rubicunda, Parvodontia gloeocystidiata, Phaeophlebiopsis roumeguerei, and Rhizochaete galactites. Hyphodermella albostraminea is considered to be a synonym of Hyphodermella pallidovirens. Ceriporia pseudocystidiata is considered to be a synonym of Meruliopsis rubicunda. Meruliopsis faginea is considered to be a synonym of Meruliopsis albostraminea. Typifications are suggested for Corticium seriale subsp. pallidolivens, Kneiffia avellanea, Corticium roumeguerei, Peniophora moelleriana, Grandinia ocellata, Corticium lividum, Thelephora viscosa var. uvida, and Radulum pendulum.

  Phellodon is a globally distributed genus of stipitate hydnoid fungi recognised by a white spore print and an ectomycorrhizal life strategy. In Europe, many Phellodon species have declining populations and are used as indicators of forests with high conservation values. However, their use in this context and the correct assessment of their extinction risk, according to IUCN guidelines, are currently hampered by inconsistent name usage and unclear species delimitations, primarily within the species complexes of P. melaleucus, P. niger and P. tomentosus. We analysed 286 ITS sequences of Phellodon, of which 51 were also analysed in conjunction with the corresponding LSU regions. This work included 102 newly sequenced collections, primarily sourced from Sweden and the UK. Our phylogenetic results show that four species are new to science and hence we formally describe P. castaneoleucus within the P. melaleucus morphological complex, P. aquiloniniger and P. frondosoniger within the P. niger complex and P. dititomentosus as a sister species to P. tomentosus . The combination P. melilotinus is made to accommodate an additional, previously described, species that belongs in the P. niger complex. We designate lectotypes and epitypes for P. melaleucus, P. niger and P. tomentosus as well as an epitype for P. melilotinus. Phellodon ellisianus is recorded as new to Europe and the ecological amplitude of P. secretus and P. violaceus is revealed to be wider than previously believed. We provide a key to all 13 species currently known in Europe and assign them to three habitat-based assemblages based on data from the Nordic countries and the UK. We hope this will facilitate the assessment of such habitats for legal protection and other conservation-related actions.

  Based on seven- and three-gene datasets, we discuss four alternative approaches for a reclassification of Fomitopsidaceae (Polyporales, Basidiomycota). After taking into account morphological diversity in the family, we argue in favour of distinguishing three genera only, viz. Anthoporia, Antrodia andFomitopsis. Fomitopsis becomes a large genus with 128 accepted species, containing almost all former Fomitopsis spp. and most species formerly placed in Antrodia, Daedalea and Laccocephalum. Genera Buglossoporus, Cartilosoma, Daedalea, Melanoporia, Neolentiporus, alongside twenty others, are treated as synonyms of Fomitopsis. This generic scheme allows for morphologically distinct genera in Fomitopsidaceae, unlike other schemes we considered. We provide arguments for retaining Fomitopsis and suppressing earlier (Daedalea, Caloporus) or simultaneously published generic names (Piptoporus) considered here as its synonyms. Taxonomy of nine species complexes in the genus is revised based on ITS, ITS +TEF1, ITS +TEF1 +RPB1 and ITS +TEF1 +RPB2 datasets. In total, 17 species are described as new to science, 26 older species are reinstated and 26 currently accepted species names are relegated to synonymy. A condensed identification key for all accepted species in the genus is provided.

  Abstract UNITE (https://unite.ut.ee) is a web-based database and sequence management environment for molecular identification of eukaryotes. It targets the nuclear ribosomal internal transcribed spacer (ITS) region and offers nearly 10 million such sequences for reference. These are clustered into ∼2.4M species hypotheses (SHs), each assigned a unique digital object identifier (DOI) to promote unambiguous referencing across studies. UNITE users have contributed over 600 000 third-party sequence annotations, which are shared with a range of databases and other community resources. Recent improvements facilitate the detection of cross-kingdom biological associations and the integration of undescribed groups of organisms into everyday biological pursuits. Serving as a digital twin for eukaryotic biodiversity and communities worldwide, the latest release of UNITE offers improved avenues for biodiversity discovery, precise taxonomic communication and integration of biological knowledge across platforms.

  Cerrenaceae is a small family of polypores and hydnoid fungi in the order Polyporales (Basidiomycota). The family consists of white-rot fungi, some of which are serious tree pathogens. Combining morphological evidence with a phylogenetic dataset of six genetic markers, we revise generic concepts in the family and propose a seven-genus classification system for the family. Two genera are introduced as new: the monotypic Acanthodontia for Radulodon cirrhatinus, and Lividopora for the Rigidoporus vinctus complex. We re-introduce the name Somion for the Spongipellis delectans complex. Other recognized genera in the family are Cerrena, Irpiciporus, Pseudolagarobasidium, and Radulodon. New species introduced are Irpiciporus branchiformis from Tanzania, Lividopora armeniaca, and L. facilis from Southeast Asia, and Somion strenuum from East Asia. We provide nomenclatural comments on all the names combined to the above Cerrenaceae genera and typify Cerrena unicolor, C. zonata, Polyporus carneopallens (=L. vincta), Somion occarium, and S. unicolor. The genus Hyphoradulum belongs to Cystostereaceae (Agaricales), and we transfer the type species H. conspicuum to Crustomyces. Our study highlights the importance of integrating different basidiocarp types in analyses when revising genus classification in macrofungi.

  Lagarobasidium cymosum is a rare corticioid species with characteristic morphology different from other Lagarobasidium species. We used nuc 5.8S rDNA, nuc 28S rDNA, and mt 12S rDNA loci to infer the phylogenetic position of L. cymosum. Our analyses suggest that it belongs to Xylodon but is not closely related to any of the other taxa referred to Lagarobasidium. Molecular and morphological information shows that the traditional concept of L. cymosum covers at least three species: Xylodon acuminatus from the Neotropics, X. cymosus from North America, and X. subtilissimus distributed in both Europe and North America. Lagarobasidium calongei is transferred to Xylodon, and DNA barcodes for Lyomyces incrustatus and Xylodon hjortstamii are published for the first time.

  Taxonomy of Basidiodendron caesiocinereum complex is revised based on morphological and molecular methods (with the use of nc LSU rDNA, ITS and TEF1 regions). The basidiospore ornamentation is justified as a key morphological character for the species recognition in the group. As redefined here, B. caesiocinereum is an angiosperm-dwelling species with smooth basidiospores. Bourdotia cinerella and B. cinerella var. trachyspora are proved to represent separate species with warted basidiospores; they are reintroduced as Basidiodendron cinerellum and B. trachysporum. Additionally, eight new species related to B. caesiocinereum are described based on material from Eurasia, North America and Africa, and identity of B. spinosum from Oceania is discussed.

  With the change to one scientific name for fungal taxa, generic names typified by species with sexual or asexual morph types are being evaluated to determine which names represent the same genus and thus compete for use. In this paper generic names of the Agaricomycotina (Basidiomycota) were evaluated to determine synonymy based on their type. Forty-seven sets of sexually and asexually typified names were determined to be congeneric and recommendations are made for which generic name to use. In most cases the principle of priority is followed. However, 16 generic names are recommended for use that do not have priority and thus need to be protected: Aleurocystis over Matula; Armillaria over Acurtis and Rhizomorpha; Asterophora over Ugola; Botryobasidium over Acladium, Allescheriella, Alysidium, Haplotrichum, Physospora, and Sporocephalium; Coprinellus over Ozonium; Coprinopsis over Rhacophyllus; Dendrocollybia over Sclerostilbum and Tilachlidiopsis; Diacanthodes over Bornetina; Echinoporia over Echinodia; Neolentinus over Digitellus; Postia over Ptychogaster; Riopa over Sporotrichum; Scytinostroma over Artocreas, Michenera, and Stereofomes; Tulasnella over Hormomyces; Typhula over Sclerotium; and Wolfiporia over Gemmularia and Pachyma. Nine species names are proposed for protection: Botryobasidium aureum, B. conspersum, B. croceum, B. simile, Pellicularia lembosporum (syn. B. lembosporum), Phanerochaete chrysosporium, Polyporus metamorphosus (syn. Riopa metamorphosa), Polyporus mylittae (syn. Laccocephalum mylittae), and Polyporus ptychogaster (syn. Postia ptychogaster). Two families are proposed for protection: Psathyrellaceae and Typhulaceae. Three new species names and 30 new combinations are established, and one lectotype is designated.

  Abstract The taxonomy of Sistotremastrum (Trechisporales, Basidiomycota) is revised based on morphology and DNA data. The genus is shown to be polyphyletic, and therefore it is split into two units— Sistotremastrum s. str. and Sertulicium , gen. nov. (typified with Corticium niveocremeum ). Sistotremastrum s. str. is retained for eleven species of which eight are described as new while Sertulicium encompasses at least six species, including one new to science. Both of these genera are only distantly related to other representatives of the Trechisporales. Additionally, a new poroid neotropical species, Porpomyces abiens ( Hydnodontaceae ), is described as morphologically similar to some members of Sistotremastrum s. str.

  The taxonomy of Protomerulius and Heterochaetella is revised based on DNA data and morphological evidence, and their type species, P. brasiliensis and H. dubia, are proved to be congeneric. As a consequence, H. dubia and related species, of which four are described as new, are placed in Protomerulius. Heterochaete microspora is also combined in Protomerulius, and the genus concept is redefined to encompass effused species with smooth or spiny hymenophore and monomitic hyphal structure. Psilochaete multifora, gen. and spec. nov. is a distant relative of Protomerulius spp. found in Norway. Heterochaetella cystidiophora is re-collected in Brazil and placed in the synonyms of Heterochaete sanctae-catharinae. This species does not belong to the Protomerulius–Heterochaetella lineage, and it is transferred to Metulochaete, gen. nov.

  Nomenclatural type definitions are one of the most important concepts in biological nomenclature. Being physical objects that can be re-studied by other researchers, types permanently link taxonomy (an artificial agreement to classify biological diversity) with nomenclature (an artificial agreement to name biological diversity). Two proposals to amend the International Code of Nomenclature for algae, fungi, and plants (ICN), allowing DNA sequences alone (of any region and extent) to serve as types of taxon names for voucherless fungi (mainly putative taxa from environmental DNA sequences), have been submitted to be voted on at the 11th International Mycological Congress (Puerto Rico, July 2018). We consider various genetic processes affecting the distribution of alleles among taxa and find that alleles may not consistently and uniquely represent the species within which they are contained. Should the proposals be accepted, the meaning of nomenclatural types would change in a fundamental way from physical objects as sources of data to the data themselves. Such changes are conducive to irreproducible science, the potential typification on artefactual data, and massive creation of names with low information content, ultimately causing nomenclatural instability and unnecessary work for future researchers that would stall future explorations of fungal diversity. We conclude that the acceptance of DNA sequences alone as types of names of taxa, under the terms used in the current proposals, is unnecessary and would not solve the problem of naming putative taxa known only from DNA sequences in a scientifically defensible way. As an alternative, we highlight the use of formulas for naming putative taxa (candidate taxa) that do not require any modification of the ICN.

  The taxonomy of the corticioid fungi from the class Atractiellomycetes (Pucciniomycotina, Basidiomycetes) currently addressed to the genus Helicogloea, is revised based on morphological and nuclear ribosomal DNA (ITS and LSU) data. The genus is restricted to 25 species with semitranslucent, gelatinous basidiocarps lacking differentiated cystidia and clamps on hyphae, of which 11 are described as new to science. The asexual genus Leucogloea is placed as a synonym of Helicogloea s. str. Since the type species of Saccoblastia, S. ovispora, is combined to Helicogloea, a new genus, Saccosoma, is introduced to encompass Saccoblastia farinacea and six related species, one of which is described as new. In contrast to Helicogloea in the strict sense, the basidiocarps of Saccosoma are arid, not gelatinized, and hyphae are clamped. The third lineage of the corticioid Atractiellomycetes is represented by the Bourdotigloea vestita complex. Species of Bourdotigloea are devoid of clamps but often possess well-differentiated cystidia, as well as long, cylindrical-fusiform basidiospores. Bourdotigloea encompasses nine species, of which six are described here as new. corticioid species phylogeny rust fungi taxonomy

  Cryptic species could represent a substantial fraction of biodiversity. However, inconsistent definitions and taxonomic treatment of cryptic species prevent informed estimates of their contribution to biodiversity and impede our understanding of their evolutionary and ecological significance. We propose a conceptual framework that recognizes cryptic species based on their low levels of phenotypic (morphological) disparity relative to their degree of genetic differentiation and divergence times as compared to non-cryptic species. We discuss how application of a more rigorous definition of cryptic species in taxonomic practice will lead to more accurate estimates of their prevalence in nature, better understanding of their distribution patterns on the tree of life, and increased abilities to resolve the processes underlying their evolution.

  Loss of natural forests and decline in forest biodiversity has led to several policy initiatives in recent years. Despite this, the importance of smaller set-asides vs forest reserves for conservation measures is poorly understood. We aimed to evaluate the importance of three different area-based conservation mea- sures commonly used in north-European forests; retention patches, woodland key habitats and forest nature reserves. We did this for two contrasting ecological systems; fungi in late-decay spruce logs and beetles in early-decay aspen snags. Eight replicated sites for each of the three conservation measures were investigated in a total of four boreal forest landscapes in south-Norway. Fungi were surveyed on existent late-decay spruce logs in two landscapes, and beetles trapped on experimentally added aspen dead-wood units in three land- scapes. Richness and species composition were analyzed separately for specialist and generalist species. We found larger differences in species composition between conservation measures for old-growth fungi specialists than generalists, although species richness patterns were less clear. The main contrast was found between nature reserves and retention patches. On the other hand, specialist beetles associ- ated with early-decay aspen showed no difference between set-asides. The assemblage of aspen gener- alist beetles tended to be richest in the woodland key habitats and showed clear differences between the conservation measures. There was considerable variation in response to conservation measures between landscapes, related to quality of the set-asides. Species specialized to an ephemeral, early-decay system were able to utilize such substrates in all of the conservation measures, while the smaller and more modified set-asides could not cater for the spe- cialists dependent on stable, late-decay systems. Species with broader habitat demands in general responded to all conservation measures. We conclude that retention patches, woodland key habitats and forest reserves fill complementary functions for wood-living species in boreal forest and should all be part of future forest conservation strategies

  One new order, one new family, and one new combination are presented, as the result of molecular phylogenetic analyses. The new order Stereopsidales and the new family Stereopsidaceae are described incorporating Stereopsis radicans and S. globosa, formerly Clavulicium globosum. We show that not only do these species represent an old overlooked lineage, but both species harbor cryptic diversity. In addition, a third species, C. macounii, appears as a plausible sister to the new lineage, but there is conflict in the data. All specimens of S. radicans and S. globosa analysed here are from the South and Central Americas; several records of S. radicans have been made also from tropical Asia. We expect the true diversity in this group to be a lot higher than presented in this paper. Stereopsis radicans was formerly included in Polyporales, but a placement within that order is rejected by our data through SH tests. The dataset consisted of four nuclear markers: rpb2, tef1, LSU and SSU, each of which was analysed separately using maximum likelihood and Bayesian inference. Recombination detection tests indicate no plausible recombinations. The potential of S. radicans, S. globosa and C. macounii being amphitallic is briefly discussed.

  The genus Brevicellicium encompasses wood-inhabiting corticioid fungi characterized by isodiametric subhymenial hyphae, short basidia, and smooth, often subangular spores with a distinct apiculus. Eight new LSU nrDNA sequences and 13 new ITS nrDNA of this genus, including the type species, were aligned with 47 and 42 accessions respectively of species of Trechisporales obtained from GenBank, and phylogenetic analyses were performed. The order Trechisporaleswas confirmed as a monophyletic group; the genera Porpomyces, Sistotremastrum, Subulicystidium and Trechispora form a highly supported clade where all Brevicellicium sequences are included. Our analyses also support that this genus belongs to Hydnodontaceae. A new species, Brevicellicium atlanticum from the Azores Archipelago, is described.

  The species composition of wood-inhabiting fungi (polypores and corticoids) was investigated on 1138 spruce logs and 992 pine logs in 90 managed and 34 natural or near-natural spruce and pine forests in SE Norway. Altogether, the study included 290 species of wood-inhabiting fungi. Comparisons of logs with similar properties (standardized tree species, decay class, dimension class) in natural and managed forests showed a significant reduction in species number per log in managed spruce forests, but not in managed pine forests. The species number per log in managed spruce forests was 10–55% lower than on logs from natural spruce forests. The reduction was strongest on logs of large dimensions. A comparison of 200–400 spruce logs from natural and managed forests showed a 25% reduction in species richness corresponding to a conservative loss of ca. 40 species on a regional scale. A closer inspection revealed that species confined to medium and very decayed spruce logs were disfavored in managed forests, whereas species on early decay classes and decay generalists were unaffected. Similarly, species preferring large spruce logs were disfavored in managed forests. Forest management had strongest impact on low-frequent species in the spruce forests (more than 50% reduction), whereas common species were modestly affected. Corticoid fungi were more adversely affected than polypore fungi. These results indicate that wood-decaying fungi in pine forests are more adapted to forest disturbances than spruce-associated species. Management measures securing a continuous supply of dead wood are more important in spruce forests than in pine forests.

  The Global Consortium for the Classification of Fungi and fungus-like taxa is an international initiative of more than 550 mycologists to develop an electronic structure for the classification of these organisms. The members of the Consortium originate from 55 countries/regions worldwide, from a wide range of disciplines, and include senior, mid-career and early-career mycologists and plant pathologists. The Consortium will publish a biannual update of the <i>Outline of Fungi and funguslike taxa</i>, to act as an international scheme for other scientists. Notes on all newly published taxa at or above the level of species will be prepared and published online on the <i>Outline of Fungi</i> website (<a href=https://www.outlineoffungi.org/>https://www.outlineoffungi.org/</a>), and these will be finally published in the biannual edition of the <i>Outline of Fungi and fungus-like taxa</i>. Comments on recent important taxonomic opinions on controversial topics will be included in the biannual outline. For example, ‘to promote a more stable taxonomy in <i>Fusarium</i> given the divergences over its generic delimitation’, or ‘are there too many genera in the <i>Boletales</i>?’ and even more importantly, ‘what should be done with the tremendously diverse ‘dark fungal taxa?’ There are undeniable differences in mycologists’ perceptions and opinions regarding species classification as well as the establishment of new species. Given the pluralistic nature of fungal taxonomy and its implications for species concepts and the nature of species, this consortium aims to provide a platform to better refine and stabilise fungal classification, taking into consideration views from different parties. In the future, a confidential voting system will be set up to gauge the opinions of all mycologists in the Consortium on important topics. The results of such surveys will be presented to the International Commission on the Taxonomy of Fungi (ICTF) and the Nomenclature Committee for Fungi (NCF) with opinions and percentages of votes for and against. Criticisms based on scientific evidence with regards to nomenclature, classifications, and taxonomic concepts will be welcomed, and any recommendations on specific taxonomic issues will also be encouraged; however, we will encourage professionally and ethically responsible criticisms of others’ work. This biannual ongoing project will provide an outlet for advances in various topics of fungal classification, nomenclature, and taxonomic concepts and lead to a community-agreed classification scheme for the fungi and fungus-like taxa. Interested parties should contact the lead author if they would like to be involved in future outlines.

  Rapporten presenterer resultater fra et samarbeidsprosjekt mellom NINA og NORSKOG. Vi har sammenliknet samme type død ved i de tre forvaltningskategoriene naturreservat, nøkkel-biotop og slutthogsthensyn (kantsoner og gjensatte grupper av livsløpstrær), og sett på artsan-tall og -sammensetning av både biller i nydød osp og sopp på granlæger. Undersøkelsen er foretatt i fire ulike landskaper i Sørøst-Norge, nær Oslo, i sør- til mellomboreal sone. Gran er dominerende treslag, og alle stokkene har vært valgt ut fra blåbær- eller småbregneskog. For insektsundersøkelsen, som ble utført i tre av landskapene, ble det felt ferske ospetrær, kappet i lengder på 1 meter. De ble plassert ut stående og parvis med 1,5 meters mellomrom, ett par per prøveflate. Alle tre arealavsetningskategorier ble studert i tre landskap, med 24 stokkpar i hvert av dem, 72 stokkpar totalt. En vindusfelle ble festet til hver stokk. Med to stok-ker var det mulig å sammenlikne billemangfoldet som ble tiltrukket av stokkene med det som faktisk ble produsert i stokkene. For å få til dette ble en av stokkene tildekket med et nett an-nethvert år, etter at begge var åpne for kolonisering i år 1. Vindusfellen hang inne i nettet og fanget insekter som klekket fra stammen. Av vedlevende billearter som inngår i analysen her, ble det registrert 345 arter med til sammen 13208 individer, av 573 arter fanget totalt. Mange arter ble funnet i lave antall; 60 vedlevende arter (17 % av alle vedlevende arter) kun med ett individ. Den vanligste arten, kortvingen Hap-loglossa villosula, forekom med 775 individer (6 % av alle vedlevende individer). 154 av de vedlevende artene er tilknyttet osp i større eller mindre grad, mens 11 har osp som eneste eller foretrukne treslag. Til sammen 21 arter er truet eller nær truet. Både vanlige og rødlistede biller som er tilpasset å leve i nydød osp, syntes langt på vei å kun-ne utnytte slikt substrat uavhengig av om det var lokalisert i et naturreservat, en nøkkelbiotop eller i et slutthogsthensyn. Biller som er spesialisert til å leve i nydød osp, ble fanget i lik arts-rikdom i våre eksperimentstokker i alle tre kategoriene, mens de øvrige ospeassosierte billear-tene hadde høyest artsrikdom i tilknytning til stokker som stod i nøkkelbiotopene. Slutthogst-hensyn-stokkene tiltrakk seg det høyeste artsmangfold av vedlevende biller totalt, inkludert mange arter som ikke kan leve i våre eksperimentstokker. Dette indikerer at forekomst av til-strekkelige mengder egnet dødved-substrat er viktigere enn hvor i landskapet det forekommer, for denne gruppen av biller og i våre studielandskap. Vedboende sopp ble registrert på 390 granstokker, fem for hvert par av ospestokker. For to av landskapene ble alle de tre kategoriene undersøkt, mens for de to øvrige landskapene ble stu-dert bare naturreservat og nøkkelbiotop. Til sammen ble det registrert 205 arter av vedboende sopp, fordelt på 30 poresopper, 169 barksopper og 8 corticoide heterobasidiomyceter. Hele 69 arter ble bare funnet én gang, mens fem arter hadde over hundre stokkforekomster. Totalt ble det observert 23 rødlistearter. Disse utgjorde 161 (5,9 %) av totalt 2745 stokkforekomster. I tillegg ble det undersøkt et antall granlæger i granplantasjer med ungskog, samt foretatt noen mer kvalitative studier i mer påvirket gammelskog. Svært få av disse stokkene hadde rødliste-artsforekomster.
