Carcinomyces polyporinus

Carcinomyces polyporinus is a species of fungus in the class Tremellomycetes. It is a parasite, growing in the hymenia of various poroid fungi, particularly species of Postia. Microscopically, it resembles a species of Tremella, but DNA research indicates that it belongs in a different family, the Carcinomycetaceae. It was first described by British mycologist Derek Reid from Scotland. It has also been recorded in continental Europe and North America.
