Haploporus species have a worldwide distribution and 27 species have been accepted. In this study, two new species, Haploporuscrystallinus and H.dextrinoideus, are proposed from South America, based on the molecular fragments (ITS, LSU and mtSSU) and morphological evidence. Molecular clock analysis was performed and the result suggests that the ancestor of Polyporales originated between the Late Jurassic and Early Cretaceous period, with a mean stem of 159.8 Mya [95% higher posterior density (HPD) of 142.4-184.1 Mya] and the genus Haploporus occurred at a mean stem of 108.3 Mya (95% HPD of 88.5-128.2 Mya). In addition, most species of the genus are diversified between 60.5 Mya and 1.8 Mya, during the Paleogene to Neogene. A key to the accepted species of the genus Haploporus is provided.

Fuscoporia is a cosmopolitan, poroid, wood-decaying genus, belonging to the Hymenochaetales. During a study of wood-inhabiting fungi in the USA, four unknown specimens were collected from Hawaii. Both morphological criteria and molecular genetic analyses based on the ITS+nLSU+EF1-α datasets and the nLSU dataset confirmed that these four specimens represent two new species of Fuscoporia, and they are described as F. hawaiiana and F. minutissima. Fuscoporia hawaiiana is characterized by pileate basidiocarps, the absence of cystidioles, hooked hymenial setae, broadly ellipsoid to subglobose basidiospores measuring 4-6 × 3.5-4.5 μm. Fuscoporia minutissima is distinguished by small pores (10-13 per mm) and basidiospores (3.4-4 × 2.4-3 μm). The taxonomic status of the two new species is briefly discussed. A key to the North American species of Fuscoporia is provided.

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.

Two new species in Hymenochaetaceae, Fulvifomes acaciae and Pyrrhoderma nigra, are illustrated and described from tropical Asia and America based on morphology and phylogenetic analyses. F. acaciae is characterized by perennial, pileate, and woody hard basidiomata when fresh; ash gray to dark gray, encrusted, concentrically sulcate, and irregularly cracked pileal surface; circular pores of 7-8 per mm with entire dissepiments; a dimitic hyphal system in trama and context; absence of setal element and presence of cystidioles; and broadly ellipsoid, yellowish brown, thick-walled, and smooth basidiospores measuring 5-6 μm × 4-5 μm. P. nigra is characterized by perennial and resupinate basidiomata with dark gray to almost black pore surface when fresh; small and circular pores of 7-9 per mm, a monomitic hyphal system with generative hyphae simple septate, hyphoid setae dominant in subiculum but not in tube trama, and absence of cystidia; and ellipsoid, hyaline, thin-walled basidiospores measuring 4-5 μm × 3-3.6 μm. The differences between the new species and morphologically similar and phylogenetically related species are discussed. Keys to Fulvifomes and Pyrrhoderma have also been provided.

Most known brown rot-producing species of Polyporales belong to the so-called "Antrodia clade" that largely consists of poroid species. In this study, we use three genetic markers to revise Antrodia s. str., the core group of this clade. We show that a corticioid species with a smooth hymenophore, Phlebia griseoflavescens, belongs to Antrodia s. str. Accordingly, we revise the generic concept of Antrodia s. str. to accommodate this species and two recently described poroid taxa, A. tenerifensis and A. multiformis. In addition, we describe two new poroid species within Antrodia s. str., A. latebrosa from Africa and A. peregrina from East Asia, and provide new documentation for the Southeast Asian species A. parvula based on recent collections from the type location.

The genus Fuscoporia of the Hymenochaetaceae is characterized by resupinate to pileate basidiocarps, a dimitic hyphal system with fine crystal aggregates and encrusted generative hyphae in dissepiment edge and tube trama, the presence of hymenial setae, and hyaline, thin-walled, smooth basidiospores. Members of the F. contigua group are easy to distinguish from other species of Fuscoporia because of the moderately large pores, presence of mycelial setae, and large hymenial setae. Here, we explore phylogenetic relationships among 20 species of Fuscoporia based on examination of some 90 collections sampled worldwide. Seven new species are recognized in the F. contigua group-F. americana, F. centroamericana, F. costaricana, F. latispora, F. monticola, F. septiseta, and F. sinica-described from China, Costa Rica, Mexico, and the United States. Phylogenetic analyses inferred from DNA sequences of the nuc rDNA internal transcribed spacer (ITS1-5.8S-ITS2 = ITS), D1-D2 domains of nuc 28S rDNA (28S), and translation elongation factor EF-1 alpha (tef1) support the F. contigua group as one of two major clades within Fuscoporia comprising nine species worldwide.
Porodaedalea is a polypore genus of the Hymenochaetales that encompasses pathogens of conifer trees. In this study, we conduct a comprehensive study of the phylogeny and diversity of Porodaedalea based on collections and isolates from Europe, North America, North Africa, and Asia. Phylogenetic analysis of a two-gene data set, nuc ribosomal DNA internal transcribed spacers (ITS1-5.8S-ITS2 = ITS) and translation elongation factor 1-alpha (tef1), shows that 20 terminal clades that correspond to phylogenetic species well supported within Porodaedalea. Based on morphological evidence, five new species, P. alpicola, P. indica, P. kesiyae, P. microsperma, and P. yunnanensis, are described and illustrated. In addition, four still unnamed lineages are detected in North America and East Asia.

Previously, Pyrrhoderma accommodated two polypore species, P. adamantinum and P. scaurum; however, phylogenetic studies indicated that these two species were not congeneric within the Hymenochaetaceae and that P. adamantinum formed a clade with Phellinidium noxium. To resolve the relationships among the two species of Pyrrhoderma and other related taxa, specimens from China, Costa Rica, Singapore, and Thailand were studied from both morphological and phylogenetic perspectives. A new genus, Fulvoderma, is erected to accommodate F. scaurum comb. nov., and a new species, F. australe (the generic type). Pyrrhoderma is delimited to include the generic type, P. sendaiense (a later synonym of P. adamantinum); two new combinations, P. lamaënse comb. nov., and P. noxium comb. nov.; and three new species, P. hainanense, P. thailandicum, and P. yunnanense. In addition, an undescribed lineage including several specimens from subtropical and tropical forests in China, Costa Rica, Singapore, and Thailand also nested within the Pyrrhoderma clade. However, as the voucher specimens are sterile or almost so, they are not described. The concept of Pyrrhoderma was emended to also accommodate species bearing resupinate, effuse-reflexed basidiocarps, hymenial or hyphoid setae, and non-subglobose basidiospores. Keys to Fulvoderma and Pyrrhoderma are provided.

Fomitiporella accommodates polypores producing annual to perennial basidiocarps with an indistinct subiculum (very thin to almost lacking), mostly a dimitic hyphal structure, lacking any kind of setae, with brownish, thick-walled basidiospores, and causing a white rot. Previously, only a few samples of Fomitiporella were studied on the basis of morphological and nuc 28S rDNA (28S)-based phylogenetic analyses. In this study, we made a comprehensive study on Fomitiporella on the basis of collections from Central America, USA, Europe, and China. The phylogenetic analysis, including 28 nuc 28S rDNA and 29 nuc rDNA ITS1-5.8S-ITS2 (internal transcribed spacer [ITS]) sequences newly generated, discovered 14 new lineages. Combined with morphological evidence, 4 new lineages are described and illustrated as new species, viz., Fomitiporella americana, F. micropora, F. sinica, and F. subinermis; 10 other new lineages, each with a single collection, are still treated as unidentified taxa; three new combinations, viz., Fomitiporella tenuissima, F. chinensis, and F. resupinata, are proposed. In addition, F. inermis is redescribed. A key to the 12 known species of Fomitiporella is provided.

Taxonomy and phylogeny of the Antrodia serialis group are revised with morphological, ecological, and geographic data, partial translation elongation factor 1-α (tef1) gene sequences, and nuc rDNA ITS1-5.8S-ITS2-28S sequences. The group contains 13 species found in boreal and temperate zones of the Northern Hemisphere. The species are limited to certain geographic areas within Eurasia and North America. The traditional morphology-based concept of A. serialis covers at least four closely related species: A. serialis s. str. in Eurasia, A. angusta, sp. nov., in East Asia, A. serrata, sp. nov., in the American Northeast, and A. calcitrosa, sp. nov., in the American Northwest. They all are associated mostly with Picea spp. and show small, but stable morphological differences from each other. In addition, A. morganii, comb. nov., inhabiting wood of Populus spp., occurs in North America, and Antrodia alaskana, comb. nov., a large-pored species, macroscopically similar to A. variiformis, is distributed along the Pacific coast of North America. The pine-dwelling A. flavimontis, sp. nov., similar to A. primaeva from Eurasia, is so far known only from the eastern part of the Rocky Mountains (Utah and Wyoming).
