The family Melanommataceae is a group of fungi within the order Pleosporales of the class Dothideomycetes. Members of this family are primarily saprobic, growing on decaying wood, bark, or plant debris, though some may be weakly parasitic. They are characterized by producing darkly pigmented, often carbonaceous ascomata (fruiting bodies) with bitunicate asci, which contain the sexual spores. The spores are typically hyaline to brown, septate, and sometimes ornamented, aiding in identification. Melanommataceae species play an important role in decomposition and nutrient cycling in forest ecosystems and are often studied for their ecological significance and taxonomic diversity.
