Belongs within: Agaricomycetes.
The Stereaceae is a group of fungi producing usually non-stalked fruiting bodies, often growing on wood. Phylogenetic analysis suggests that the genus Aleurodiscus is paraphyletic to other genera in the family (Binder et al. 2005).
Characters (from Cannon & Kirk 2007, for Stereaceae): Basidiomata appressed, effused-reflexed or discoid, rarely stalked, the outer surface often zoned, usually leathery or waxy. Hyphal system dimitic (rarely trimitic), typically differentiated into a hairy or hirsute outer skin, a closely woven cortex, and loose hyphae curving up to the hymenium, hyphae with simple septa, thick-walled cystidia common. Hymenium smooth to tuberculate or rugose. Basidia small and narrow, 4-spored, sometimes accompanied by ornamented paraphysis-like hyphae. Basidiospores ellipsoidal to cylindrical, hyaline, smooth, sometimes staining in iodine.
