Abstract

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.

  • Oct 2022
Phlebiodontia is proposed as a new genus in the Meruliaceae based on morphological and molecular data. The genus is typified by Phlebiodontia rajchenbergii, a new species proposed for Brazil, and also includes P. acanthocystis (Hawaii) and P. subochracea (Germany), which are new combinations proposed in this study. The species of Phlebiodontia are morphologically characterized by yellowish ceraceous basidiomes, with slightly warted to hydnoid hymenophore, monomitic hyphal system, clamped generative hyphae, presence of smooth thin-walled cystidia and broadly ellipsoid to allantoid basidiospores. The phylogenetic relationships of Phlebiodontia and the related taxa in Meruliaceae were inferred from a 4-locus dataset including nuc rDNA ITS1-5.8S-ITS2 (ITS), the D1-D2 domains of 28S rDNA (28S), RNA polymerase II largest subunit (rpb1) and translation elongation factor 1- (tef1). This work presents complete descriptions, comments and discussion about morphology and distribution of Phlebiodontia species.

  • Jun 2023
Phylogenetic and morphological analyses on Rigidoporus were carried out. The genus Rigidoporus (Hymenochaetales, Basidiomycota), typified by R. microporus (Fr.) Overeem. (synonym Polyporus micromegas Mont.), was established by Murrill in 1905. The genus is mainly characterized by annual to perennial, resupinate, effused-reflexed to pileate or stipitate basidiomata with azonate or concentrically zonate and sulcate upper surface, a monomitic to pseudo-dimitic hyphal structure, simple-septate generative hyphae, and ellipsoid to globose basidiospores. Phylogeny on species of the genus is reconstructed with two loci DNA sequences including the internal transcribed spacer regions and the large subunit. Three new species in Rigidoporus are described and illustrated from Asia, and one new combination in the genus is proposed. The main morphological characteristics of the currently accepted species of Rigidoporus are provided.

Systematic classification and phylogenetic relationships of the brown-rot fungi within the Polyporales
Article
Full-text available
  • Sep 2022
The brown-rot fungi play an important role in forest ecosystems; they can degrade celluloses and hemicelluloses of wood and maintain nutrient cycling. Some of the brown-rot fungi also have important economic value as medicinal or edible mushrooms. Recent studies showed that the ability to produce brown rot has evolved independently at least five times. Nevertheless, the Polyporales contains the vast majority of the species of the brown-rot fungi. In this study, the classification system of the brown-rot fungi within the Polyporales is revised. Furthermore, the phylogenetic relationships of brown-rot fungi within the Polyporales are analysed based on DNA sequences of multiple loci including the internal transcribed spacer (ITS) regions, the large subunit nuclear ribosomal RNA gene (nLSU), the small subunit nuclear ribosomal RNA gene (nSSU), the small subunit mitochondrial rRNA gene sequences (mtSSU), the translation elongation factor 1-α gene (TEF1), the RNA polymerase II largest subunit (RPB1) and the second subunit of RNA polymerase II (RPB2). The study showed that the brown-rot fungi within the Polyporales formed fourteen lineages, which are assigned at family level, including four new families: Auriporiaceae, Piptoporellaceae, Postiaceae, Taiwanofungaceae, and ten existing families: Adustoporiaceae, Dacryobolaceae, Fibroporiaceae, Fomitopsidaceae, Laetiporaceae, Laricifomitaceae, Phaeolaceae, Pycnoporellaceae, Sarcoporiaceae, and Sparassidaceae. Meanwhile, eleven new genera, viz., Austroporia, Aurantipostia, Austropostia, Daedalella, Nothofagiporus, Pseudoantrodia, Pseudofomitopsis, Rhodoantrodia, Tenuipostia, Wolfiporiella and Wolfiporiopsis are proposed; eighteen new species, viz., Amyloporia nivea, Antrodia subheteromorpha, Aurantipostia macrospora, Austropostia hirsuta, A. plumbea, A. subpunctata, Cystidiopostia subhibernica, Daedalella micropora, Fuscopostia subfragilis, Lentoporia subcarbonica, Melanoporia tropica, Neolentiporus tropicus, Phaeolus fragilis, Postia crassicontexta, Pseudoantrodia monomitica, Pseudofomitopsis microcarpa, Resinoporia luteola and Rhodonia subrancida are described; and twelve new combinations, viz., Austroporia stratosa, Austropostia brunnea, A. pelliculosa, A. punctata, Nothofagiporus venatus, Rhodoantrodia tropica, R. yunnanensis, Tenuipostia dissecta, Wolfiporiella cartilaginea, W. curvispora, W. dilatohypha and Wolfiporiopsis castanopsidis, are proposed. Illustrated descriptions of the new species are provided. Notes on the genera of brown-rot fungi within the Polyporales are provided.

A comparison of polypore funga and species composition in forest ecosystems of China, North America, and Europe
Article
  • Jun 2022
Background Polypores as components of forest ecosystems are an important group of wood-inhabiting fungi playing a key role in forest regeneration. Previously, studies on polypore funga and diversity were focused on limited areas within one land mass only. What are the polypore funga and species composition for large-scale of China, North America and Europe? The funga and species composition of polypores in the three land masses will supply an important source of reference for the distribution patterns of polypores at species level or higher taxa. In the present study the diversity and species composition of polypores in China, North America and Europe are compared based on published data. Methods The species diversity, species composition, major genera and nutritional modes of polypores in the three land masses are comparatively analyzed. Results A grand total of 1,337 polypore species, belonging to 11 orders, 43 families and 168 genera, have been recorded in these three land masses of the Northern Hemisphere, of which 854 species occur in China, 547 species in North America, and 432 species in Europe. Polyporales, Hymenochaetales and Russulales are the three major orders, and Hymenochaetaceae, Polyporaceae, and Fomitopsidaceae are the three major families. The brown rot fungi Antrodia and Postia have highest number of species at generic level in the three land masses. The proportionally highest number of white rot polypore species is in China (78.81%), followed by North America (73.86%) and then Europe (67.82%); conversely, the proportion of brown rot polypores is highest in Europe (28.47%) then North America (21.39%) and then China (15.57%). Conclusions China had the highest polypore diversity followed by North America, and then Europe although North America is around twice as big as China and Europe. White rot is the major nutritional mode of all the polypores in China, North America and Europe accounting for 77.04% of all polypore species. The white rot species as a proportion of all polypores in each of the three land masses are highest in China, followed by North America and then Europe. The polypore diversity patterns are probably due to tree species diversity and the distribution patterns of angiosperm and gymnosperm trees in the three land masses. More tree species and diverse forest types are in China than those in North America and Europe, and these factors may correspond polypore funga and species composition in the three land masses.

A multi‐gene phylogeny clarifies species diversity, taxonomy, and divergence times of Ceriporia and other related genera in Irpicaceae (Polyporales, Basidiomycota)
Article
Full-text available
  • Oct 2023
Phylogenetic and morphological analyses on Ceriporia and other related genera in Irpicaceae were carried out. Ceriporia, Gloeoporus, and Meruliopsis characterised as resupinate, effused- reflexed or pileate polypores with poroid and smooth hymenophore, a monomitic hyphal structure, crystals, and an oily substance are contained in the Irpicaceae. Ceriporia and Meruliopsis are phylogenetically related as sister genera. They share resupinate to rarely effused-reflexed basidiomata with a white, buff to brightly colored hymenophore, a monomitic hyphal structure with simple septa on the generative hyphae, and ellipsoid, cylindrical to allantoid basidiospores. However, hymenial cystidia are present in most Meruliopsis species, while they are absent in most Ceriporia species. Gloeoporus is distinguished from Ceriporia and Meruliopsis by having a gelatinous hymenophore and generative hyphae, sometimes with clamp connections. Phylogenies on Ceriporia and other related genera were reconstructed using multiple loci DNA sequences, including the internal transcribed spacer regions (ITS), the large subunit of nuclear ribosomal RNA gene (nLSU), the largest subunit of RNA polymerase II (RPB1), the translation elongation factor 1- α gene (TEF1) and the small subunit of nuclear ribosomal RNA gene (nSSU), as well as two combined datasets (ITS+nLSU) and (ITS+nLSU+RPB1+TEF1+nSSU). Eleven new species in Ceriporia are described and illustrated, four new combinations in the genus are proposed. Two new species in Gloeoporus and three in Meruliopsis are described and illustrated. Moreover, the evolutionary times of Ceriporia and other related genera in Irpicaceae were revealed based on conserved regions of five DNA fragments (ITS+nLSU+RPB1+TEF1+nSSU). Bayesian evolutionary analysis shows the divergence time of Irpicaceae emerged with a mean stem age of 169.1 Mya [95 % highest posterior density (HPD) of 124.66–231.04 Mya], which occurred during the middle Jurassic. Ceriporia and Meruliopsis grouped and the initial diversification occurred during the early of the Cretaceous with a mean stem age of 113.99 Mya [95% highest posterior density (HPD) of 81.53–153.07 Mya]. Gloeoporus emerged earlier with a mean stem age of 142.84 Mya [95% highest posterior density (HPD) of 102.39–196.41 Mya], which occurred during the early Cretaceous.

Article
  • Sep 2022
Phylogenetic and morphological analyses on Spongipellis and its micromorphological similar genera, Irpiciporus, Pseudospongipellis, and Radulodon, were carried out. Phylogenies on Spongipellis are reconstructed with multiple loci DNA sequences including the internal transcribed spacer (ITS) regions, the large subunit (nLSU), and the small subunit (nSSU) of nuclear ribosomal RNA gene and the translation elongation factor 1-α gene (TEF1). The results demonstrate the polyphyly of Spongipellis, including two genera nested in the different family clades. Pseudospongipellis gen. nov. is established including three new combinations. Three new species, Irpiciporus sinuosus, Radulodon yunnanensis, and Spongipellis quercicola spp. nov., are described and illustrated. A key to the Spongipellis and its micromorphological similar genera is provided.

A revised family-level classification of the Polyporales ( Basidiomycota )
Article
Full-text available
  • Jun 2017
Polyporales is strongly supported as a clade of Agaricomycetes, but the lack of a consensus higher-level classification within the group is a barrier to further taxonomic revision. We amplified nrLSU, nrITS and rpb1 genes across the Polyporales, with a special focus on the latter. We combined the new sequences with molecular data generated during the PolyPEET project and performed Maximum Likelihood and Bayesian phylogenetic analyses. Analyses of our final 3-gene dataset (292 Polyporales taxa) provide a phylogenetic overview of the order that we translate here into a formal family-level classification. Eighteen clades are assigned a family name, including three families described as new (Cerrenaceae fam. nov., Gelatoporiaceae fam. nov., Panaceae fam. nov.) and fifteen others (Dacryobolaceae, Fomitopsidaceae, Grifolaceae, Hyphodermataceae, Incrustoporiaceae, Irpicaceae, Ischnodermataceae, Laetiporaceae, Meripilaceae, Meruliaceae, Phanerochaetaceae, Podoscyphaceae, Polyporaceae, Sparassidaceae, Steccherinaceae). Three clades are given informal names (/hypochnicium,/climacocystis and/fibroporia+amyloporia). Four taxa (Candelabrochete africana, Mycoleptodonoides vassiljevae, Auriporia aurea and Tyromyces merulinus) cannot be assigned to a family within the Polyporales. The classification proposed here provides a framework for further taxonomic revision and will facilitate communication among applied and basic scientists. A survey of morphological, anatomical, physiological and genetic traits confirms the plasticity of characters previously emphasized in taxonomy of Polyporales.

Diversity of Wood-Inhabiting Polyporoid and Corticioid Fungi in Odaesan National Park, Korea
Article
Full-text available
  • Dec 2016
Polyporoid and corticioid fungi are among the most important wood-decay fungi. Not only do they contribute to nutrient cycling by decomposing wood debris, but they are also valuable sources for natural products. Polyporoid and corticioid wood-inhabiting fungi were investigated in Odaesan National Park. Fruit bodies were collected and identified based on morphological and molecular analyses using 28S and internal transcribed spacer regions of DNA sequences. As a result, a total of 149 species, 69 genera, 22 families, and 11 orders were recognized. Half (74 species) of the species were polypores, and the other half (75 species) were corticioid fungi. Most of the species belonged to Polyporales (92 species) followed by Hymenochaetales (33 species) and Russulales (11 species). At the genus level, a high number of species was observed from Steccherinum, Hyphodontia, Phanerochaete, Postia, and Trametes. Concerning distribution, almost all the species could be found below 1,000 m, and only 20% of the species were observed from above 1,000 m. Stereum subtomentosum, Trametes versicolor, T. hirsuta, T. pubescens, Bjerkandera adusta, and Ganoderma applanatum had wide distribution areas. Deciduous wood was the preferred substrate for the collected species. Sixty-three species were new to this region, and 21 species were new to Korea, of which 17 species were described and illustrated.

The boreal zone and its biotic subdivision
Article
A preliminary map of the latitudinal, transcontinental subzones of the Eurasian and North American circumboreal vegetation zone is presented. The recognized subzones are called herniboreal, southern boreal, middle boreal and northern boreal. Along the humidity ‑ aridity gradient the zone may be divided into several sectors (not mapped). The highly humid sectors may be characterized by treeless heaths, and birch and/or alder woods or ‘krummholz’ thickets, while moderately humid sectors are pri­marily dominated by coniferous forests. In the arid sectors there are areas of aspen and larch woods and even boreal steppe vegetation.
