Thin-walled Maze Polypore (Daedaleopsis confragosa) specializes in breaking down hardwood logs. Fruiting bodies have no apparent stalk, may arise singly or in clusters, and have caps with alternating zones of earthy browns and tans. The pores on the under surface vary in shape and can be round, elongated, maze-like, or even gill-like. Their tendency to turn red when bruised is a useful identification feature.
