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.

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).

Antrodia is a polyphyletic genus, comprising brown-rot polypores with annual or short-lived perennial resupinate, dimitic basidiocarps. Here we focus on species that are closely related to Antrodia crassa, and investigate their phylogeny and species delimitation using geographic, ecological, morphological and molecular data (ITS and LSU rDNA, tef1). Phylogenetic analyses distinguished four clades within the monophyletic group of eleven conifer-inhabiting species (five described herein): (1)A. crassa s. str. (boreal Eurasia), Antrodia cincta sp. nova (North America) and Antrodia cretacea sp. nova (holarctic), all three being characterized by inamyloid skeletal hyphae that dissolve quickly in KOH solution; (2) Antrodia ignobilis sp. nova, Antrodia sitchensis and Antrodia sordida from North America, and Antrodia piceata sp. nova (previously considered conspecific with A. sitchensis) from Eurasia, possessing amyloid skeletal hyphae; (3) Antrodia ladiana sp. nova from the southern part of the USA, Antrodia pinea from East Asia, and Antrodia ferox - so far known from subtropical North America, but here reported also from Eurasia. These three species have inamyloid hyphae and narrow basidiospores; (4) the North American Antrodia pini-cubensis, sharing similar morphological characters with A. pinea, forming a separate clade. The habitat data indicate that several species are threatened by intensive forestry.
