Species diversity of pathogenic wood-rotting fungi (Agaricomycetes, Basidiomycota) in China
Wood-rotting basidiomycetes have been investigated in the Chinese forest ecosystem for the past 30 years. Two hundred and five pathogenic wood-decayers belonging to 9 orders, 30 families, and 74 genera have been found in Chinese native forests, plantations, and gardens. Seventy-two species (accounting for 35% of the total pathogenic species) are reported as pathogenic fungi in China for the first time. Among these pathogens, 184 species are polypores, nine are corticioid fungi, eight are agarics and five are hydnoid basidiomycetes. One hundred and seventy-seven species (accounting for 86%) cause white rot, while 28 species (accounting for 14%) result in brown rot; 157 species grow on angiosperm trees (accounting for 76.5%) and 44 species occur on gymnosperm trees (accounting for 21.5%), only four species inhabit both angiosperms and gymnosperms (accounting for 2%); 95 species are distributed in boreal to temperate forests and 110 in subtropical to tropical forests. In addition, 17 species, including Fomitopsis pinicola, Heterobasidion parviporum, and Phellinidium weirii etc. which were previously treated as pathogenic species in China, do not occur in China according to recent studies. In this paper, the host(s), type of forest, rot type, and distribution of each pathogenic species in China are given.

What is the correct scientific name for \Fuling\ medicinal mushroom?
In recent years, the scientific names of many cultivated and well-known medicinal fungal species have been changed. However, the results of taxonomic and nomenclature works on these economically important fungi are often overlooked or ignored in applied researches. The incorrect use of scientific names may cause uncertainty in research and in the global medicinal mushroom market. In this paper, we briefly review the current taxonomy and nomenclature of \"Fuling\" medicinal mushroom and make a proposal for biochemists, pharmacists and businessmen on the correct use of scientific names related to this species. Based on the recent taxonomic results and nomenclatural proposals, the use of the names Wolfiporia extensa, W. cocos and especially Poria cocos for the \"Fuling\" mushroom are incorrect and misleading; therefore, the acceptance of the names Pachyma hoelen or Wolfiporia hoelen is recommended.

A contribution to Porogramme (Polyporaceae, Agaricomycetes) and related genera
The polypores with shallow pores from tropical Asia and America are studied. Our molecular phylogeny based on the internal transcribed spacer (ITS), the large subunit nuclear ribosomal RNA gene (nLSU), the translation elongation factor 1-α gene (TEF1), and the largest subunit of RNA polymerase II (RPB1) demonstrates six clades are formed among
Porogramme
and related genera. Two new genera,
Cyanoporus
and
Pseudogrammothele
, are established, and the six clades represent
Porogramme
,
Cyanoporus
,
Grammothele, Epithele, Theleporus
, and
Pseudogrammothele
, respectively. The molecular clock analyses estimate the divergence times of the six clades based on a dataset (ITS + LSU + TEF1 + RPB1 + RPB2), and we recognize the mean stem ages of the six genera are earlier than 50 Mya. Three new species in
Porogramme
were morphologically and phylogenetically confirmed, and they are described as
P. austroasiana
,
P. cylindrica
, and
P. yunnanensis
. Phylogenetic analysis shows that type species of
Tinctoporellus
and
Porogramme
are nested in the same clade, and
Tinctoporellus
is treated as a synonym of
Porogramme.
Based on our phylogeny, twelve new combinations are proposed, and the differences between the new species and similar or related species are discussed.

Global Diversity and Updated Phylogeny of Auricularia (Auriculariales, Basidiomycota)
Auricularia has a worldwide distribution and is very important due to its edibility and medicinal properties. Morphological examinations and multi-gene phylogenetic analyses of 277 samples from 35 countries in Asia, Europe, North and South America, Africa, and Oceania were carried out. Phylogenetic analyses were based on ITS, nLSU, rpb1, and rpb2 sequences using methods of Maximum Likelihood and Bayesian Inference analyses. According to the morphological and/or molecular characters, 37 Auricularia species were identified. Ten new species, A. camposii and A. novozealandica in the A. cornea complex, A. australiana, A. conferta, A. lateralis, A. pilosa and A. sinodelicata in the A. delicata complex, A. africana, A. srilankensis, and A. submesenterica in the A. mesenterica complex, are described. The two known species A. pusio and A. tremellosa, respectively belonging to the A. mesenterica complex and the A. delicata complex, are redefined, while A. angiospermarum, belonging to the A. auricula-judae complex, is validated. The morphological characters, photos, ecological traits, hosts and geographical distributions of those 37 species are outlined and discussed. Morphological differences and phylogenetic relations of species in five Auricularia morphological complexes (the A. auricula-judae, the A. cornea, the A. delicata, the A. fuscosuccinea and the A. mesenterica complexes) are elaborated. Synopsis data on comparisons of species in the five complexes are provided. An identification key for the accepted 37 species is proposed.

Phylogeny and diversity of the morphologically similar polypore genera Rigidoporus, Physisporinus, Oxyporus, and Leucophellinus
Rigidoporus and its morphologically similar genera Physisporinus, Oxyporus, and Leucophellinus, which include some forest pathogens and medicinal species, are very important groups of wood-decaying fungi. Species of these genera have not only ecological functions, but also economic importance. Phylogenetic and taxonomic studies on taxa in these genera were carried out. Inferred from phylogenies based on DNA sequences of the nuc rDNA ITS1-5.8S-ITS2 (internal transcribed spacer [ITS]) and D1-D2 domains of nuc 28S rDNA, 36 species sampled that traditionally belong to Physisporinus, Rigidoporus, Leucophellinus, and Oxyporus are nested mostly in eight lineages. Of these lineages, five (including four genera of Physisporinus, Emmia, Flaviporus, and Flavodon and one taxon \"R. hypobrunneus\") belong to Polyporales and three (including the genera Rigidoporus, Bridgeoporus, and Leucophellinus) belong to Hymenochaetales. Rigidoporus and Oxyporus are merged because the type species of both genera are nested in a single lineage within Hymenochaetales. Some taxon previously placed in Ceriporia and Oxyporus are transferred to Emmia and Flavodon, respectively, on the basis of current phylogeny. Utilizing a combination of the morphological and phylogenetic evidence, 16 new combinations in Bridgeoporus, Emmia, Flaviporus, Flavodon, Rigidoporus, and Physisporinus are proposed. Five new species, Physisporinus crataegi, P. lavendulus, P. subcrocatus, P. tibeticus, and Rigidoporus submicroporus, are recognized from China. Illustrated descriptions of these novel species are provided. Three taxa are treated at the generic level of Physisporinus because of limited samples.

Global diversity and phylogeny of Incrustoporiaceae (Polyporales, Basidiomycota) with an emphasis on Skeletocutis
This study presents the taxonomy and phylogeny of the family Incrustoporiaceae, based on comprehensive phylogenetic analyses utilising multi-gene data, including the internal transcribed spacer regions (ITS) and the large subunit of the nuclear ribosomal RNA gene (nLSU), for the accepted genera within Incrustoporiaceae. Additionally, a separate phylogenetic analysis focusing on the Skeletocutis nivea complex was performed using ITS sequences. A total of 20 new species within the genus Skeletocutis are described, namely Skeletocutis crystallina, S. cunninghamiae, S. cylindrica, S. ellipsoidea, S. flavipora, S. latemarginata, S. liangdongii, S. monocotyledona, S. montanus, S. neoalbomarginata, S. oceanica, S. ochraceocarpa, S. quercicola, S. sinica, S. sinoalbomarginata, S. sinochrysella, S. subamorpha, S. subdiluta, S. subkrawtzewii, and S. sublilacina. Detailed illustrated descriptions, voucher specimens, hosts, distribution, diagnoses, and remarks are provided for these 20 new species. Additionally, two new combinations are proposed: S. minutula and Tyromyces subodorus. Notably, our discoveries of S. oceanica and S. subdiluta in Australia underscore the significance of expanding research on Skeletocutis diversity in the Southern Hemisphere, where reports are scarce. Phylogenetic analyses also clarified the taxonomic positions of Skeletocutis and Tyromyces within the Incrustoporiaceae family, showing that Tyromyces is nested within the polyphyletic Skeletocutis clade. The morphological distinctions between Skeletocutis and Tyromyces, as well as between Skeletocutis and Sidera, are also discussed.

Phylogeny and species diversity of Armillaria in China based on morphological, mating test, and GCPSR criteria
More than 600 Chinese specimens of Armillaria were identified by mating tests, Genealogical Concordance Phylogenetic Species Recognition (GCPSR), and comparison of morphological characteristics. Sixteen Chinese Biological Species (CBS) of Armillaria were identified by 30,340 mate pair combinations. Fifteen Chinese Phylogenetic Species (CPS) were recognised based on Independent Evolutionary Lineage (IEL) recognition and concatenated six-gene analysis (actin, h3h, hisps, LSU rDNA, rpb1, and tef1α). All the biological species and phylogenetic species were identical and possessed the same species boundary, except for CBS K (A. mellea) and CBS G (A. mellea ssp. nipponica) which were the same phylogenetic species. On the basis of CBS and CPS, eight new species of Armillaria in China were distinguished using macro and micro morphology, and they are described as A. algida, A. amygdalispora, A. bruneocystidia, A. luteopileata, A. pungentisquamosa, A. sinensis, A. tibetica, and A. violacea. This study indicates that the GCPSR approach provides the same resolution as mating tests in identification of Armillaria species.

Large-scale phylogenomic insights into the evolution of the Hymenochaetales
The Hymenochaetales is an order with most species as wood-inhabiting fungi that have high phylogenetic complexity and morphological diversity. Species in this order play important roles in forest ecosystems and include wood decomposers, pathogens, and those that form ectomycorrhizal associations. However, we have limited knowledge of the patterns of large-scale evolutionary history of the order. In this study, using 171 genomes, including 113 newly assembled, we reconstructed the phylogenomic relationships, divergence times, biogeographic patterns, morphological evolution of basidiomata, and patterns of speciation/extinction in the Hymenochaetales. The phylogenomic relationships of 12 families within the Hymenochaetales suggested that 10 families can be accepted, and 2 families rejected. Molecular clock dating analyses suggested that the Hymenochaetales possibly started a rapid family-wide and genus-wide radiation during the early Cretaceous to late Jurassic and Cretaceous, respectively. Reconstruction of the ancestral state implied that Hymenochaetales probably originated from the temperate regions of Asia, with the basidiomata of the common ancestor likely being a corticioid species that rapidly transformed between the early Cretaceous and late Jurassic, coinciding with radiations at the family level. Furthermore, we detected a gradually increasing trend of speciation, extinction, and net diversification rates. We provided large-scale genomes of the Hymenochaetales and revealed evolutionary history patterns, which are key to understanding the evolution of fungi.
