- Agaricomycetes includes ca. 21,000 described species of mushroom-forming fungi that function as decayers, pathogens, and mutualists in both terrestrial and aquatic habitats. The morphological diversity of Agaricomycete fruiting bodies is unparalleled in any other group of fungi, ranging from simple corticioid forms to complex, developmentally integrated forms (e.g., stinkhorns). In recent years, understanding of the phylogenetic relationships and biodiversity of Agaricomycetes has advanced dramatically, through a combination of polymerase chain reaction-based multilocus phylogenetics, phylogenomics, and molecular environmental surveys. Agaricomycetes is strongly supported as a clade and includes several groups formerly regarded as Heterobasidiomycetes, namely the Auriculariales, Sebacinales, and certain Cantharellales (Tulasnellaceae and Ceratobasidiaceae). The Agaricomycetes can be divided into 20 mutually exclusive clades that have been treated as orders. This chapter presents an overview of the phylogenetic diversity of Agaricomycetes, emphasizing recent molecular phylogenetic studies.

Tidskriftsartikel (refereegranskat)abstract
- The phylogeny of the poroid and hydnoid genera Antrodia, Junghuhnia, and Steccherinum (Polyporales, Basidiomycota) was studied utilizing sequences of the gene regions ITS, nLSU, mtSSU, atp6, rpb2 and tef1. Altogether 148 taxa, represented by 549 sequences, were included in analyses. Results show that most species of these genera form a well supported clade in the Polyporales, called Steccherinaceae, along with 12 other hydnoid and poroid genera. Within the Steccherinaceae, generic concepts need to be revised: no fewer that 15 genera are needed to accommodate existing and new species. At least 16 transitions have taken place between poroid and hydnoid hymenophore types within Steccherinaceae, and similar plasticity can be seen in microscopic characters. Nevertheless, natural genera revealed in the analysis can mostly be characterized morphologically and, with few exceptions, poroid and hydnoid species belong to separate genera. The genus Steccherinaceae in shown to contain both hydnoid and poroid species. Species of the former Antrodiella belong to at least 10 genera within Steccherinaceae.
