POLYPORUS

Polyporus is a genus of hymenomycetous fungi with over a hundred British species. They for a type of the family Polyporae in which the hymenium, or spore-bearing surface, lines the interior of closely-packed tubes on the under side of the pileus. The species are chiefly found growing on trees and stumps, with only a few species living on the ground, and many are stalkless.
