Genus Antrodia P. Karst.

Meddelanden af Societas pro Fauna et Flora Fennica 5: 40 (1879)

Type species: Polyporus serpens Fr., Observationes mycologicae 2: 265 (1818)

Gilbertson and Ryvarden (1986) describe 20 species of Antrodia for North America. They restrict the genus to ones causing a brown rot. Characters for the genus include generative hyphae with clamps, skeletal hyphae (dimitic hyphal system), and spores that are hyaline, thin-walled, smooth, non-amyloid, and cylindrical to oblong ellipsoid. There has been much morphological and phylogenetic work done since then and this group is dispersed across many genera.

This group is poorly known for the Chicago Region. We are just beginning to determine which species are present. I have been calling some of them waterfall polypore for the way the pores cascade down the wood surface. Some of the species likely to be here on hardwood, based on the literature and collections are A. favescens, A. heteromorpha, plus Antrodia malicola and A. serialis have 1900-1918 Chicago Region collections at UC and NY. But A. serialis in the strict sense is apparently absent from North America (Spirin et al. 2017).

Molecular phylogenies (see links below) show that the genus Antrodia in the broad sense is polyphyletic. It is scattered across multiple clades in combination with other genera, such as Fomitopsis and Daedalea. A new, most restricted, sense for Antrodia centers around its type species A. serpens. The species in the A. heteromorpha group have large pores and were classified in Daedalea by Fries. The species concepts became confused over time but are now clarified in Spirin et al. (2013). Antrodia serpens is not a synonym of Antrodia albida. But they consider Antrodia albida a synonym of A. heteromorpha. The synonymy on Index Fungorum and Mycobank has not been updated to reflect this new work. Antrodia sinuosa was moved to Amyloporia sinuosa.
