Melanomma pulvis-pyrius (Pleosporales) is a widespread fungus that belongs to the Melanomataceae. This species is saprotrophic on debris of numerous trees and shrubs, especially Fagus, but its ecological significance is unknown. Black spherical ascomata occur in clusters from winter to spring and Melanomma pulvis-pyrius also produces a so-called Aposphaeria asexual state. It is frequently encountered in microhabitats including rot holes and surface rot, but it is not clear whether an endophytic stage is involved in the life cycle of the fungus. The rot produced by Melanomma pulvis-pyrius progresses slowly and contributes to higher pH levels, which enables numerous epiphytic fungal and bryophyte species to colonize the same substrate.
