The genus Fomitopsis (Polyporales, Basidiomycota) reconsidered.

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 and Fomitopsis. 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.

A revised genus-level classification for Cerrenaceae (Polyporales, Agaricomycetes).

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.

Revision of Cerinomyces (Dacrymycetes, Basidiomycota) with notes on morphologically and historically related taxa.

Cerinomyces (Dacrymycetes, Basidiomycota) is a genus traditionally defined by corticioid basidiocarps, in contrast to the rest of the class, which is characterized by gelatinous ones. In the traditional circumscription the genus is polyphyletic, and the monotypic family Cerinomycetaceae is paraphyletic. Aiming for a more concise delimitation, we revise Cerinomyces s.l. with a novel phylogeny based on sequences of nrDNA (SSU, ITS, LSU) and protein-coding genes (RPB1, RPB2, TEF1-α). We establish that monophyletic Cerinomyces s.s. is best characterized not by the corticioid morphology, but by a combination of traits: hyphal clamps, predominantly aseptate thin-walled basidiospores, and low content of carotenoid pigments. In our updated definition, Cerinomyces s.s. encompasses five well-supported phylogenetic clades divided into two morphological groups: (i-iii) taxa with arid corticioid basidiocarps, including the generic type C. pallidus; and (iv-v) newly introduced members with gelatinous basidiocarps, like Dacrymyces enatus and D. tortus. The remaining corticioid species of Cerinomyces s.l. are morphologically distinct and belong to the Dacrymycetaceae: our analysis places the carotenoid-rich Cerinomyces canadensis close to Femsjonia, and we transfer the clamps-lacking C. grandinioides group to Dacrymyces. In addition, we address genera related to Cerinomyces s.l. historically and morphologically, such as Ceracea, Dacryonaema and Unilacryma. Overall, we describe twenty-four new species and propose nine new combinations in both Cerinomycetaceae and Dacrymycetaceae.

[The modern characteristics of occupational morbidity of agriculture workers].

On the basis of updated data from 82 subjects of the Russian Federation multivariate analysis of occupational diseases of agricultural workers was implemented. It is established that in unhealthy work conditions are characteristic for 30% of workers in the agricultural sector. In the enterprises of agriculture, the percentage of workplaces not meeting sanitary hygienic standards made up to 35%. The high etiologic pathogenic relationship between nosological form of disease and working conditions in the profession is established. Most often, the occupational pathology was developed in agricultural workers in case of conditions of physical overload (37.2%), effecting of physical factors (26.8%) and contact with infected animals (14.6%). In nosological structure of accumulated occupational diseases the first place took radiculopathy of cervical and lumbar sacral levels (23%), the second - vibration disease (15.3%), followed by brucellosis (14.6%), the fourth - neuro-sensory deafness (11.5%). The regions of the Russian Federation are characterized by pronounced heterogeneity both related to general level of registered occupational diseases and its nosological spectrum. In the whole, in Russia during 2011-2015 persistent trend of decreasing of occupational diseases morbidity of agricultural workers was marked.

Hydnoporia, an older name for Pseudochaete and Hymenochaetopsis, and typification of the genus Hymenochaete (Hymenochaetales, Basidiomycota).

The genus name Hydnoporia is reinstated to encompass the Hymenochaete tabacina group currently addressed to Pseudochaete (illegitimate genus) or Hymenochaetopsis. Identity of the type species of Hydnoporia, Sistotrema fuscescens (= Hydnoporia olivacea in current sense), is clarified, and a lectotype is selected. In total, 12 species are combined in Hydnoporia: H. corrugata, H. gigasetosa, H. lamellata, H. laricicola, H. latesetosa, H. lenta, H. rhododendri, H. rimosa, H. subrigidula, H. tabacina, H. tabacinoides, and H. yasudai. Hydnoporia diffissa is described as new. Analyses of all available ITS (94) and newly produced tef1 sequences (20) indicate that there are at least 20-27 species in the genus. Identity of the type species of Hymenochaete, H. rubiginosa, is clarified; the name is retained for the species so named in Europe while other species are present in North America and East Asia. Additionally, three new combinations in Hymenochaete are proposed: H. campylopora (= Cyclomyces fuscus), H. microcycla (= Cyclomyces tabacinus), and H. saepiaria.

A preliminary overview of the corticioid Atractiellomycetes (Pucciniomycotina, Basidiomycetes).

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.

Postia caesia complex (Polyporales, Basidiomycota) in temperate Northern Hemisphere.

Taxonomy of the Postia caesia complex is revised based on morphology and two genetic markers, ITS and tef1. In total, we recognize 24 species, multiplying the known species diversity in the complex. We provide descriptions for 20 temperate Northern Hemisphere taxa. Identity of the core species, P. caesia, is re-established, and a neotype from the type locality is selected. Four new combinations are proposed, and 10 new species are described: P. arbuti, P. auricoma, P. bifaria, P. comata, P. cyanescens, P. glauca, P. livens, P. magna, P. populi, and P. yanae.
