Synonyms: Hypolyssus polyporinus, Peckiella polyporina.
Hypomyces polyporinus is a parasitic fungus that infects various species of polypore fungi, particularly those in the genus Trametes. In East and Central Texas, it has been found on hosts such as Trametes versicolor and Trametes hirsuta, typically growing on dead logs, stumps, and fallen branches in deciduous forests. The fungus produces a bright orange to yellowish-orange, powdery to downy coating on the surface of its host, eventually forming perithecia that contain ascospores. It is relatively common in the region, particularly during the summer and fall months when its hosts are most active.
