Ischnoderma

Ischnoderma is a genus of polypore fungi. Species in the genus have dark brown and tomentose fruit bodies that become darker brown to black and smooth when mature. The genus, widespread in temperate regions, contains an estimated 10 species.

==Taxonomy== Ischnoderma was circumscribed by Finnish mycologist Petter Adolf Karsten in 1879. Although Ischnoderma has traditionally been classified in the family Fomitopsidaceae, Phylogenetic studies have demonstrated its isolated phylogenetic position in the Polyporales. Justo and colleagues suggest that Ischnoderma would be better placed as the type genus of Ischnodermataceae, a family originally proposed by Walter Jülich in 1981. The generic name Ischnoderma combines the Ancient Greek words ("dry") and ("skin").
