Fomitopsis

Fomitopsis is a genus of more than 40 species of bracket fungi in the family Fomitopsidaceae.

==Taxonomy== The genus was circumscribed by Finnish mycologist Petter Karsten in 1881 with Fomitopsis pinicola as the type species. Molecular analysis indicates that Fomitopsis belongs to the antrodia clade, which contains about 70 percent of brown-rot fungi. Other genera that join Fomitopsis in the core antrodia group include Amyloporia, Antrodia, Daedalea, Melanoporia, Piptoporus, and Rhodonia. Studies have indicated that Fomitopsis and Piptoporus were phylogenetically heterogenous, and the type of that genus, Piptoporus betulinus, is in the Fomitopsis core group. This fungus, well known for its use by Ötzi the Iceman, was transferred to Fomitopsis in 2016.
