Fomes fasciatus and F. fomentarius have ranges that overlap slightly in Tennessee and North Carolina. Fomes fasciatus, however, is essentially a southern and subtropical species and F. fomentarius is a boreal species. F. fomentarius basidiomata tend to be more consistently ungulate and typically have a concave pore surface. Basidiocarps of F. fasciatus vary greatly from applanate to ungulate and generally have a convex pore surface. Microscopically, they differ in the larger spores of F. fomentarius (Gilbertson & Ryvarden 1986).
Why suggested for a Global Red List Assessment?
Species widely distributed, with highest occurrence in Brazil.
Population and Trends
Species well distributed, with about 720 occurrences according to GBIF.
Population Trend: Uncertain
Habitat and Ecology
This species occurs in five Brazilian biomes: Amazon, Cerrado, Pampa, Atlantic Forest and Caatinga.
It presents no evident threat, being very common at least in Brazil. However, it is found in the Atlantic Forest, a hotspot, in the Amazonia (currently being deforested at the highest rates in the last decades) and Cerrado (also a hotspot). Also, Caatinga is threatened with desertification.
