Species of Amylascus are closely related to truffles ( Pachyphlodes , Luteoamylascus ) and cup fungi ( Plicariella ) from the Northern Hemisphere. Here we reevaluate the species diversity of Amylascus and related taxa from southern South America and Australia based on new morphological and molecular data. We identify previously undocumented diversity and morphological variability in ascospore color, ascospore ornamentation, hymenial construction, epithecium structure and the amyloid reaction of the ascus in Melzer’s reagent. We redescribe two Amylascus species from Australia and describe seven new Amylascus species, five from South America and two from Australia. This is the first report of Amylascus species from South America. We also describe the new South American genus Nothoamylascus as sister lineage to the Pachyphlodes - Amylascus - Luteoamylascus clade (including Amylascus , Luteoamylascus , Pachyphlodes , and Plicariella ). We obtained ITS sequences of mitotic spore mats from Nothoamylascus erubescens gen. & sp. nov. and four of the seven newly described Amylascus species, providing the first evidence of mitotic spore mats in Amylascus . Additional ITS sequences from mitotic spore mats reveal the presence of nine additional undescribed Amylascus and one Nothoamylascus species that do not correspond to any sampled ascomata. We also identify three additional undescribed Amylascus species based on environmental sequences from the feces of two ground-dwelling bird species from Chile, Scelorchilus rubecula and Pteroptochos tarnii . Our results indicate that ascomata from Amylascus and Nothoamylascus species are rarely collected, but molecular data from ectomycorrhizal roots and mitotic spore mats indicate that these species are probably common and widespread in southern South America. Finally, we present a time-calibrated phylogeny that is consistent with a late Gondwanan distribution. The time since the most recent common ancestor of: 1) the family Pezizaceae had a mean of 276 Ma (217–337 HPD); 2) the Amylascus - Pachyphlodes - Nothoamylascus - Luteoamylascus clade had a mean of 79 Ma (60–100 HPD); and 3) the Amylascus - Pachyphlodes clade had a mean of 50 Ma (38–62 HPD). The crown age of Pachyphlodes had a mean of 39 Ma (25–42 HPD) and Amylascus had a mean age of 28 Ma (20–37 HPD), falling near the Eocene-Oligocene boundary and the onset of the Antarctic glaciation (c. 35 Ma).","PeriodicalId":20014,"journal":{"name":"Persoonia","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136008597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

European members of the group are characterised by the absence of bright colours on the surfaces of their pilei, the context turning grey to black after cutting, the abundance of short lamellulae in the hymenophore, and spores with an inamyloid suprahilar spot and with low reticulate ornamentation. Our multi-locus phylogenetic study confirmed that this morphological delimitation corresponds to a well-supported clade. Within this clade, 16 species are recognised in Europe, of which five belong to the R. albonigra lineage and were described in a previous study, while eleven are fully described in this study. The application of the names R. acrifolia , R. adusta , R. anthracina , R. atramentosa , R. densissima , R. nigricans and R. roseonigra is based on the position of sequences retrieved from types or authentic material. Based on type sequences, R. fuliginosa is synonymised with R. anthracina and two varieties of R. anthracina are considered synonyms of R. atramentosa . The application of the name R. densifolia is based on a morphological match with the traditional species interpretation and the neotype specimen. Three species are described as new, R. marxmuelleriana sp. nov., R. picrophylla sp. nov. and R. thuringiaca sp. nov. This study recognises three major lineages and two species with isolated positions within the European Compactae and a morphological barcode was assigned to the species using an analysis of 23 selected characters. A search of publicly available sequences from the UNITE database revealed that the majority of species are host tree generalists and widely distributed in temperate and Mediterranean areas of Europe. Russula adusta is the only species so far proven to form ectomycorrhiza exclusively with conifers.","PeriodicalId":20014,"journal":{"name":"Persoonia","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135158313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the ubiquity of these fungi, their diversity in freshwater sediments is still poorly understood. During a survey of culturable Ascomycota from river and stream sediments in various sampling sites in Spain, we obtained 47 isolates of black yeasts by using potato dextrose agar supplemented with cycloheximide. A preliminary morphological study and sequence analyses of the internal transcribed spacer region (ITS) and the large subunit (LSU) of the nuclear rDNA revealed that most of the isolates belonged to the family Herpotrichiellaceae . We have confidently identified 30 isolates representing the following species: Capronia pulcherrima , Cladophialophora emmonsii , Exophiala equina , Exophiala pisciphila , Exophiala radicis , and Phialophora americana . However, we encountered difficulty in assigning 17 cultures to any known species within Chaetothyriales . Combining phenotypic and multi-locus phylogenetic analyses based on the ITS, LSU, β-tubulin ( tub2 ) and translation elongation factor 1-α ( tef 1-α) gene markers, we propose the new genus Aciculomyces in the Herpotrichiellaceae to accommodate the novel species Aciculomyces restrictus . Other novel species in this family include Cladophialophora denticulata , Cladophialophora heterospora , Cladophialophora irregularis , Exophiala candelabrata , Exophiala dehoogii , Exophiala ramosa , Exophiala verticillata and Phialophora submersa . The new species Cyphellophora spiralis , closely related to Cyphellophora suttonii , is described, and the phylogeny of the genus Anthopsis in the family Cyphellophoraceae is discussed. By utilizing these four markers, we were able to strengthen the phylogenetic resolution and provide more robust taxonomic assessments within the studied group. Our findings indicate that freshwater sediments may serve as a reservoir for intriguing black yeasts, which warrant further investigation to address gaps in phylogenetic relationships, particularly within Herpotrichiellaceae.","PeriodicalId":20014,"journal":{"name":"Persoonia","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135559727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This pathogen was originally described in the European hedgehog (<i>Erinaceus europaeus</i>) but is also frequently found in the African four-toed hedgehog (<i>Atelerix albiventris</i>), a popular pet animal worldwide. Little is known about the taxonomy and population genetics of this pathogen despite its increasing importance in clinical practice. Notably, whether there are different populations or even cryptic species associated with different hosts or geographic regions is not known. To answer these questions, we collected 161 isolates, performed phylogenetic and population-genetic analyses, determined mating-type, and characterised morphology and physiology. Multigene phylogeny and microsatellite analysis supported <i>T. erinacei</i> as a monophyletic species, in contrast to highly incongruent single-gene phylogenies. Two main subpopulations, one specific mainly to <i>Atelerix</i> and second to <i>Erinaceus</i> hosts, were identified inside <i>T. erinacei</i>, and slight differences in the size of microconidia and antifungal susceptibilities were observed among them. Although the process of speciation into two lineages is ongoing in <i>T. erinacei</i>, there is still gene flow between these populations. Thus, we present <i>T. erinacei</i> as a single species, with notable intraspecies variability in genotype and phenotype. The data from wild hedgehogs indicated that sexual reproduction in <i>T. erinacei</i> and de novo infection of hedgehogs from soil are probably rare events and that clonal horizontal spread strongly dominates. The molecular typing approach used in this study represents a suitable tool for further epidemiological surveillance of this emerging pathogen in both animals and humans. The results of this study also highlighted the need to use a multigene phylogeny ideally in combination with other independent molecular markers to understand the species boundaries of dermatophytes. <b>Citation</b>: Čmoková A, Kolařík M, Guillot J, et al. 2022.

However, the species diversity, phylogenetic relationships, and geographic distribution of &lt;i&gt;Tuber&lt;/i&gt; species in China remains poorly understood, primarily because descriptions of many new species relied heavily on morphological features with molecular data either not sought or ignored. The misapplication of European and North American names further added to confusion regarding the taxonomy of Chinese &lt;i&gt;Tuber&lt;/i&gt; species. In this study, we examined more than 1 000 specimens from China, and performed a comprehensive phylogenetic analysis for Chinese &lt;i&gt;Tuber&lt;/i&gt; species using ITS sequences and multilocus sequence data. To infer the phylogeny of Chinese &lt;i&gt;Tuber&lt;/i&gt; spp., 11 molecular datasets were assembled, including a concatenated internal transcribed spacers of the nuc rDNA (ITS), nuc rDNA 28S subunit (LSU), translation elongation factor 1-alpha (&lt;i&gt;tef1&lt;/i&gt;-α), and RNA polymerase II subunit (&lt;i&gt;rpb2&lt;/i&gt;) dataset as well as 10 ITS datasets (totally including 1 435 sequences from 828 collections with 597 newly generated sequences, and 168 sequences from the types of 63 species). Our phylogenetic tree based on a concatenated multilocus dataset revealed that all Chinese Tuber species nested in nine phylogenetic clades (phylogroups), including &lt;i&gt;Aestivum&lt;/i&gt;, &lt;i&gt;Excavatum&lt;/i&gt;, &lt;i&gt;Latisporum&lt;/i&gt;, &lt;i&gt;Macrosporum&lt;/i&gt;, &lt;i&gt;Maculatum&lt;/i&gt;, &lt;i&gt;Melanosporum&lt;/i&gt;, &lt;i&gt;Puberulum&lt;/i&gt;, &lt;i&gt;Rufum&lt;/i&gt; and &lt;i&gt;Turmericum&lt;/i&gt;. Of these, five phylogroups (&lt;i&gt;Macrosporum&lt;/i&gt;, &lt;i&gt;Maculatum&lt;/i&gt;, &lt;i&gt;Melanosporum&lt;/i&gt;, &lt;i&gt;Puberulum&lt;/i&gt; and &lt;i&gt;Rufum&lt;/i&gt;) are shared across the continents of Asia, Europe and North America; two phylogroups (&lt;i&gt;Aestivum&lt;/i&gt; and &lt;i&gt;Excavatum&lt;/i&gt;) are shared by Europe and Asia; and the phylogroups Turmericum and Latisporum are endemic only to Asia. Phylogenetic trees based on 10 ITS datasets confirmed the presence of at least 82 phylogenetic species in China. Of these, 53 are identified as known species, including three new records for China, and 25 species are identified as new to science. Of the new species, nine are described and illustrated in this paper, and the others remain unnamed due to the paucity or absence of ascomatal materials. Accordingly, the confirmed, excluded and doubtful Tuber species in China are discussed. Tuber species showed high endemism.

During our investigation of fungal diversity in China, a total of 356 fusarioid isolates were obtained and identified from diverse diseased and healthy plants, or different environmental habitats, i.e., air, carbonatite, compost, faeces, soil and water, representing hitherto one of the most intensive sampling and identification efforts of fusarioid taxa in China. Combining morphology, multi-locus phylogeny and ecological preference, these isolates were identified as 72 species of <i>Fusarium</i> and allied genera, i.e., <i>Bisifusarium</i> (1), <i>Fusarium</i> (60), and <i>Neocosmospora</i> (11). A seven-locus dataset, comprising the 5.8S nuclear ribosomal RNA gene with the two flanking internal transcribed spacer (ITS) regions, the intergenic spacer region of the rDNA (IGS), partial translation elongation factor 1-alpha (<i>tef1</i>), partial calmodulin (<i>cam</i>), partial RNA polymerase largest subunit (<i>rpb1</i>), partial RNA polymerase second largest subunit (<i>rpb2</i>) gene regions, and partial β-tubulin (<i>tub2</i>), were sequenced and employed in phylogenetic analyses. A genus-level phylogenetic tree was constructed using combined <i>tef1</i>, <i>rpb1</i>, and <i>rpb2</i> sequences, which confirmed the presence of four fusarioid genera among the isolates studied. Further phylogenetic analyses of two allied genera (<i>Bisifusarium</i> and <i>Neocosmospora</i>) and nine species complexes of <i>Fusarium</i> were separately conducted employing different multi-locus datasets, to determine relationships among closely related species. Twelve novel species were identified and described in this paper.

A portrait of the recently described <i>I. ianthinopes</i> is given. All species are smooth-spored and some pruinose only in the apical part of the stipe, and some on entire length. The new species are compared to 24 type specimens (17 characterized by at least partial ITS sequence data), all of which are described and revised here. Epitypes were selected for two species, <i>I. hirtella and I. sindonia</i>. Based on our studies, we confirm that <i>I. kuehneri</i> and <i>I. sindonia</i> on one hand, and <i>I. subalbidodisca</i> and <i>I. ochroalba</i> on the other, are synonyms and furthermore suggest that <i>I. abietis</i> is synonymous with <i>I. catalaunica, I. exilis with I. rufobrunnea, I. hirtellarum with I. mycenoides, I. lapidicola with I. deianae, I. ochraceolutea with I. sindonia, I. stangliana with I. pelargonium, I. subrubens</i> with <i>I. subhirtella and I. sulfovirescens</i> with <i>I. langei</i>. All of the new species are supported by phylogenetic analyses. Among the 16 previously described species accepted here, 10 are represented by types in the phylogenetic analyses and five by own collections corresponding to the type. Two species, <i>I. eutheloides</i> (remaining doubtful) and <i>I. pallidolutea</i> are only treated morphologically.
