This fungus is within the rust clade of the Basidiomycota. The mature basidiocarps may range from grey to brown and range in size from 0.45 to a few centimeters tall. Spores are 4 to 7 micrometers in diameter, spherical and orange in color. They are borne on basidia resembling those of the metabasidia other fungi in the rust clade. P. faginea is a saprobe on many species of tree, though it was originally described on the bark of living beech trees(Fagus spp.).
