Abstract
Wood-rotting fungi are important components of woody plant ecosystems and play an active role in the decomposition and turnover of nutrients from wood, and are among the major groups of Basidiomycota. In this study, a new species of wood-rotting fungus, Sistotrema yunnanense, was proposed based on morphological characteristics and molecular evidence. It is characterized by resupinate basidiomata, a monomitic hyphal system having generative hyphae with clamp connections, suburniform to urniform basidia, and short-cylindrical to oblong ellipsoid basidiospores (4.5-6.5 × 3-4 µm). Phylogenetic analyses performed using the large subunit nuc rDNA indicated that S. yunnanense was nested within the genus Sistotrema s.l. of the family Hydnaceae, within the order Cantharellales.

(<i>Cantharellales</i>) from Japan with descriptions of their ectomycorrhizae. MYCOSCIENCE 2022; 63:102-117. [PMID: 37089627 PMCID: PMC10042317 DOI: 10.47371/mycosci.2022.02.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2021] [Revised: 02/02/2022] [Accepted: 02/13/2022] [Indexed: 01/14/2023]
Abstract
We describe two new species of resupinate Sistotrema sensu lato (Cantharellales) collected in Japan: S. flavorhizomorphae and S. chloroporum. Both species have urniform basidia with more than four sterigmata and monomitic hyphal system, oil-rich hyphae in subiculum, which is typical for this genus. Sistotrema chloroporum is characterized by poroid hymenophore partly yellowish-green, basidia 4-6-spored, medium-sized basidiospores (4.5-6.5 × 3.5-6 µm), and broadleaf forest habitat. Sistotrema flavorhizomorphae is characterized by hydnoid-irpicoid hymenophore, bright yellowish rhizomorphs, basidia 6-8-spored, small basidiospores (3-3.5 × 2.5-3 µm), and pine forest habitat. Phylogenetic trees inferred from the fungal nrDNA ITS and LSU and the rpb2 sequences supported that both species were distinct and grouped with other ectomycorrhizal Sistotrema and Hydnum species, but their generic boundary was unclear. Mycorrhizae underneath basidiomes of both species were identified and described via molecular techniques. Mycorrhizae of S. chloroporum have similar characteristics to those of other Sistotrema s.l. and Hydnum species, i.e., S. confluens and H. repandum, whereas S. flavorhizomorphae has a distinct morpho-anatomy, for example, a distinct pseudoparenchymatous mantle. Comprehensive characterizations of basidiomes and mycorrhizae improve the taxonomic analysis of mycorrhizal species of Sistotrema s.l.

Abstract
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 family Hydnaceae (Cantharellales, Basidiomycota) is a group of fungi found worldwide which exhibit stichic nuclear division. The group is highly diverse in morphology, ecology, and phylogeny, and includes some edible species which are popular all over the world. Traditionally, Hydnaceae together with Cantharellaceae, Clavulinaceae and Sistotremataceae are four families in the Cantharellales. The four families were combined and redefined as "Hydnaceae", however, a comprehensive phylogeny based on multiple-marker dataset for the entire Hydnaceae sensu stricto is still lacking and the delimitation is also unclear. We inferred Maximum Likelihood and Bayesian phylogenies for the family Hydnaceae from the data of five DNA regions: the large subunit of nuclear ribosomal RNA gene (nLSU), the internal transcribed spacer regions (ITS), the mitochondrial small subunit rDNA gene (mtSSU), the second largest subunit of RNA polymerase II (RPB2) and the translation elongation factor 1-alpha gene (TEF1). We also produced three more phylogenetic trees for Cantharellus based on 5.8S, nLSU, mtSSU, RPB2 and TEF1, Craterellus and Hydnum both based on the combined nLSU and ITS. This study has reproduced the status of Hydnaceae in the order Cantharellales, and phylogenetically confirmed seventeen genera in Hydnaceae. Twenty nine new taxa or synonyms are described, revealed, proposed, or reported, including eight new subgenera (Cantharellus subgenus Magnus, Craterellus subgenus Cariosi, subg. Craterellus, subg. Imperforati, subg. Lamelles, subg. Longibasidiosi, subg. Ovoidei, and Hydnum subgenus Brevispina); seventeen new species (Ca. laevihymeninus, Ca. magnus, Ca. subminor, Cr. badiogriseus, Cr. croceialbus, Cr. macrosporus, Cr. squamatus, H. brevispinum, H. flabellatum, H. flavidocanum, H. longibasidium, H. pallidocroceum, H. pallidomarginatum, H. sphaericum, H. tangerinum, H. tenuistipitum and H. ventricosum); two synonyms (Ca. anzutake and Ca. tuberculosporus as Ca. yunnanensis), and two newly recorded species (H. albomagnum and H. minum). The distinguishing characters of the new species and subgenera as well as their allied taxa are discussed in the notes which follow them. The delimitation and diversity in morphology, ecology, and phylogeny of Hydnaceae is discussed. Notes of seventeen genera which are phylogenetically accepted in Hydnaceae by this study and a key to the genera in Hydnaceae are provided.

Abstract
High-altitude volcanoes, typical examples of extreme environments, are considered of particular interest in biology as a possible source of novel and exclusive microorganisms. We analyzed the crater soil microbial diversity of Tianchi Volcano, northeast China, by combining molecular and morphological analyses of culturable microbes, and metabarcoding based on Illumina sequencing, in order to increase our understanding of high-altitude volcanic microbial community structure. One-hundred and seventeen fungal strains belonging to 51 species and 31 genera of Ascomycota, Basidiomycota and Mucoromycota were isolated. Penicillium, Trichoderma, Cladosporium, Didymella, Alternaria and Fusarium dominated the culturable fungal community. A considerable number of isolated microbes, including filamentous fungi, such as Aureobasidium pullulans and Epicoccum nigrum, yeasts (Leucosporidium creatinivorum), and bacteria (Chryseobacterium lactis and Rhodococcus spp.), typical of high-altitude, cold, and geothermal extreme environments, provided new insights in the ecological characterization of the investigated environment, and may represent a precious source for the isolation of new bioactive compounds. A total of 1254 fungal and 2988 bacterial operational taxonomic units were generated from metabarcoding. Data analyses suggested that the fungal community could be more sensitive to environmental and geographical change compared to the bacterial community, whose network was characterized by more complicated and closer associations.

Abstract
AbstractThe Basidiomycota constitutes a major phylum of the kingdom Fungi and is second in species numbers to the Ascomycota. The present work provides an overview of all validly published, currently used basidiomycete genera to date in a single document. An outline of all genera of Basidiomycota is provided, which includes 1928 currently used genera names, with 1263 synonyms, which are distributed in 241 families, 68 orders, 18 classes and four subphyla. We provide brief notes for each accepted genus including information on classification, number of accepted species, type species, life mode, habitat, distribution, and sequence information. Furthermore, three phylogenetic analyses with combined LSU, SSU, 5.8s, rpb1, rpb2, and ef1 datasets for the subphyla Agaricomycotina, Pucciniomycotina and Ustilaginomycotina are conducted, respectively. Divergence time estimates are provided to the family level with 632 species from 62 orders, 168 families and 605 genera. Our study indicates that the divergence times of the subphyla in Basidiomycota are 406–430 Mya, classes are 211–383 Mya, and orders are 99–323 Mya, which are largely consistent with previous studies. In this study, all phylogenetically supported families were dated, with the families of Agaricomycotina diverging from 27–178 Mya, Pucciniomycotina from 85–222 Mya, and Ustilaginomycotina from 79–177 Mya. Divergence times as additional criterion in ranking provide additional evidence to resolve taxonomic problems in the Basidiomycota taxonomic system, and also provide a better understanding of their phylogeny and evolution.
