In this present study, five new wood-inhabiting fungal taxa, Botryobasidium gossypirubiginosum, Botryobasidium incanum, Botryobasidium yunnanense, Coltricia zixishanensis, and Coltriciella yunnanensis are proposed. Botryobasidium gossypirubiginosum is distinguished by its slightly rubiginous hymenial surface, monomitic hyphal system, which branches at right angles, and subglobose, smooth basidiospores (14–17.5 × 13–15.5 µm); B. incanum is characterized by its white to incanus basidiomata having a hypochnoid hymenial surface, and ellipsoid, smooth basidiospores (6.5–8.5 × 3.5–5 µm); B. yunnanense is characterized by its buff to slightly yellowish hymenial surface, monomitic hyphal system, and broadly ellipsoid to globose, smooth, thick-walled basidiospores (11.5–14.5 × 9.5–10.5 µm); Coltricia zixishanensis differs in its rust brown pileal surface, and ellipsoid, thick-walled basidiospores (5–6.5 × 4–4.5 µm). Coltriciella yunnanensis is distinguished by its tiny pilei, short stipe, and navicular, verrucose basidiospores (10.5–12.5 × 6–7 µm). Sequences of ITS and nLSU genes were used for phylogenetic analyses using the maximum likelihood, maximum parsimony, and Bayesian inference methods. The phylogenetic results inferred from ITS sequences revealed that B. gossypirubiginosum was closely related to B. robustius; the species B. incanum was grouped with B. vagum; B. yunnanense was related to B. indicum. The species C. zixishanensis was grouped with C. confluens and C. perennis. ITS sequences revealed that C. zixishanensis was grouped into the genus Coltriciella, in which it was grouped with Co. globosa and Co. pseudodependens.

Wood-decaying fungi represent a vital group of higher fungi that drive the cycling of matter and energy in forest ecosystems, and they have been the focus of thorough investigation. In this study, five new species, viz. Botryobasidium daweishanense , Inonotus subglobisporum , Kneiffiella bubalina , Xylodon granulanoides , and X. granulans from China, are described and illustrated based on the morphological characteristics and molecular phylogenetic analyses, in which the sequences of ITS+nLSU genes were used for the phylogenetic analyses by maximum likelihood and Bayesian inference methods. The phylogeny revealed that the Botryobasidium daweishanense groups with three taxa, viz. , B. intertextum , B. leptocystidiatum , and B. subcoronatum . Inonotus subglobisporum is closely related to I. radiatus. Kneiffiella bubalina clustered sister to K. subalutacea . Xylodon granulanoides and X. granulans have a close relationship with X. bambusinus , X. fissuratus , X. subclavatus , X. montanus , and X. wenshanensis . Additionally, Xylodon granulanoides and X. granulans clustered together. Botryobasidium daweishanense is characterized by an araneose hymenial surface, fusiform, and cyanophilous basidiospores (6.1–7.3 × 3.3–3.9 μm). Inonotus subglobisporum is characterized by perennial basidiomata with lateral stipes, polygon pores measuring 4–6 per mm, and subglobose, cyanophilous basidiospores (3.6–4.3 × 2.8–3.5 μm). Kneiffiella bubalina is characterized by cream basidiomata and cylindrical to slightly allantoid basidiospores (8.0–8.9 × 1.8–2.3 μm). Xylodon granulanoides is characterized by grandinioid hymenial surfaces, various cystidia, and broadly ellipsoid, thick-walled basidiospores (4.7–5.3 × 3.6–4.1 μm). Xylodon granulans is characterized by grandinioid hymenial surfaces, capitate and clavate cystidia, and broadly ellipsoid basidiospores (3.8–4.2 × 2.9–3.3 μm). Phylogenetic analysis based on internal transcribed spacer (ITS) and nuclear large subunit RNA (nLSU) shows that the four species are members of Hymenochaetales, and one belongs to Cantharellales. All five new species are compared with morphologically and phylogenetically closely related species. The present study contributes to understanding the species diversity, taxonomy, and phylogeny of macrofungi in Southwestern China.

The basidiomycete genus Botryobasidium is a resupinate saprotrophic with a global distribution range from coniferous to broad-leaved forest ecosystems. Though numerous species have been reported from Eurasia and North America, few have been described from China. In the current work, phylogenetic analyses of Botryobasidium in China were conducted based on the dataset of the internal transcribed spacer (ITS) regions and the large subunit (LSU) of nuclear ribosomal RNA gene. Maximum likelihood and Bayesian analyses were used to reconstruct the phylogenetic tree, and three new species, namely Botryobasidium acanthosporum, B. leptocystidiatum and B. subovalibasidium, were described from subtropical forests of Yunnan Province, Southwestern China. Botryobasidium acanthosporum is characterized by having yellowish white to dark yellow basidiome, clavate to tubular cystidia, and subglobose to globose basidiospores with obtuse spines. Botryobasidium leptocystidiatum is characterized by having fluffy to arachnoid, greyish white to ivory basidiome, generative hyphae with clamped, tubular cystidia, and subnavicular to navicular basidiospores. While, B. subovalibasidium is characterized by having yellowish to ivory basidiome, subovoid basidia, navicular to suburniform basidiospores, and thick-walled chlamydospores. These three new species are described and illustrated, and the discriminating characters between the new species and their closely related species are discussed. A key to known species of Botryobasidium in China is provided.

The new geographic distribution regions are recorded for Agaricus bambusetorum, Bipolaris heliconiae, Crinipellis trichialis, Leucocoprinus cretaceus, Halobyssothecium cangshanense and Parasola setulosa. Corresponding to morphological characters, phylogenetic evidence is also utilized to place the above-mentioned taxa in appropriate taxonomic positions. The current morphological and phylogenetic data is helpful for further clarification of species diversity and exploration of evolutionary relationships in the related fungal groups.

The 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.

In the years 2012–2014 mycological inventory was performed in the Kampinos National Park. The subjects of the inventory were the macrofungi (Ascomycota, Basidiomycota). The inventory was made by the route method. The area checked for the presence of the macrofungi comprised the Kampinos National Park without the buffer zone, particular attention was paid to the areas under strict protection. During the inventory 12 012 new findings of macrofungi were noted. On the basis of the own studies (1407 taxa identified in the inventory) and literature data (about 425 taxa reported in papers from 1876–2012), a list of macrofungi present in the Park was made. At present, 1533 taxa of macrofungi are known to occur in the Park, in the rank of species, variety or form, of which 1108 have been found for the first time in the last inventory. The presence of 126 species earlier reported from the Park area has not been confirmed. The list of taxa presented in the paper comprises 1359 basidiomycetous fungi (Basidiomycota), representing 327 genera and 174 ascomycetous fungi (Ascomycota), representing 80 genera. Among them there are 20 species which are protected in Poland (7 under strict protection and 13 under partial protection) and 313 species from the red list of Polish threatened macrofungi, including 4 species categorized as extinct or probably extinct (Ex category), 111 species categorized as endangered (E category), 53 species categorized as vulnerable (V category), 129 species categorized as rare (R category) and 16 species categorized as indeterminate (I category). 94 species, varieties or forms of fungi have been noted in Poland for the first time. Characterisation of the fungi found to occur in the area of KNP is given, including the division into morphological groups: ascomycetous, agaricoid, boletoid, gasteroid, hydnoid, clavarioid, corticioid, polyporoid, tremelloid and auricularioid fungi. The factors ensuring or influencing the high diversity of fungi in the area studied were analysed and attempts were made to identify the refugia and sites of particular mycological worth. The paper discusses the specificity of fungi occurring on anthropogenic habitats and areas without forest cover as well as the importance of those areas for the preservation of full diversity of KNP mycobiota. The diversity of the Park’s mycobiota was compared with the data available from other national parks in Poland. The possible threats for the diversity of macrofungal species were pointed out and some recommendations have been made to protect this group of organisms. The paper is illustrated with 17 tables of photographs showing fructifications of 94 species in situ.

Current knowledge about Italian wood-decay fungi (Basidiomycota and Ascomycota) is surveyed: 1582 taxa belonging to Ascomycota (341) and Basidiomycota (1241) have been reported, including 23 species new to science of Basidiomycota described from Italy within the last five years. Evaluating diversity of wood-decay fungi can provide a more accurate estimation of species richness for fungi which are an important functional component of ecosystems. Aphyllophoroid and Ascomycota species play an important role in habitat conservation and management. Sardinia, Sicily, the Alps and the Apennines are “hot spots” for wood-decay Basidiomycota in Italy.

Kotiranta, H. & Ryvarden, L. 2007: Botryobasidium baicalinum sp. nova (Aphyllophorales, Basidio-mycetes). — Ann. Bot. Fennici 44: 293–297. Botryobasidium baicalinum Kotir. & Ryvarden is described from Lake Baikal, south-ern Siberia, Russia. It is characterized by constantly clamped hyphae, long, thin-walled cystidia, ephemeral small basidia, smooth, thick-walled chlamydospores and navicular or subnavicular basidiospores. The new species is fairly similar to B. parvisetosum, which, however, differs in having smaller cystidia, specialized chlamydospore-bear-ing cells, ornamented chlamydospores and narrower basidiospores. The new species is illustrated and compared with B. parvisetosum.

Cortbase is a nomenclatural database for corticioid (resupinate) fungi (Corticiaceae s.l. and related hymenomycetes) with basionyms, synonyms, taxonomically correct names, data on name usage, literature references, and evaluation of nomenclatural status. It is available as an on-line service (http://andromeda.botany.gu.se/cortbase.html) and as an MS-DOS executable for local installation. The database includes 8112 species names; of the 4412 basionyms included, 2101 represent taxonomically acceptable species, 1434 are heterotypic synonyms, and 877 are of uncertain application. The improvements over the previous version include the new, platform-independent on-line search interface, some 800 more corticioid names, numerous additions to the existing data, and six new categories for searching, including searches for location of type specimens and for authors of species names.

We reassessed the circumscription of the cantharelloid clade and identified monophyletic groups by using nLSU, nSSU, mtSSU and RPB2 sequence data. Results agreed with earlier studies that placed the genera Cantharellus, Craterellus, Hydnum, Clavulina, Membranomyces, Multiclavula, Sistotrema, Botryobasidium and the family Ceratobasidiaceae in that clade. Phylogenetic analyses support monophyly of all genera except Sistotrema, which was highly polyphyletic. Strongly supported monophyletic groups were: (i) Cantharellus-Craterellus, Hydnum, and the Sistotrema confluens group; (ii) Clavulina-Membranomyces and the S. brinkmannii-oblongisporum group, with Multiclavula being possibly sister of that clade; (iii) the Sistotrema eximum-octosporum group; (iv) Sistotrema adnatum and S. coronilla. Positions of Sistotrema raduloides and S. athelioides were unresolved, as were basal relationships. Botryobasidium was well supported as the sister taxon of all the above taxa, while Ceratobasidiaceae was the most basal lineage. The relationship between Tulasnella and members of the cantharelloid clade will require further scrutiny, although there is cumulative evidence that they are probably sister groups. The rates of molecular evolution of both the large and small nuclear ribosomal RNA genes (nuc-rDNA) are much higher in Cantharellus, Craterellus and Tulasnella than in the other cantharelloid taxa, and analyses of nuc-rDNA sequences strongly placed Tulasnella close to Cantharellus-Craterellus. In contrast analyses with RPB2 and mtSSU sequences placed Tulasnella at the base of the cantharelloid clade. Our attempt to reconstruct a "supertree" from tree topologies resulting from separate analyses that avoided phylogenetic reconstruction problems associated with missing data and/or unalignable sequences proved unsuccessful.
