AI-generated description

Hypoxylon fuscum is a species of fungus in the family Hypoxylaceae. It is a pyrenomycete with a stromatized, carbonaceous, and fissured ascostroma. In St. Petersburg and Leningrad Oblast, it has been found on decaying wood, particularly on deciduous trees such as birch and alder. In north-western Russia, the fungus grows on dead branches and trunks, often in association with other fungi. Its distribution in the region is relatively common, especially in moist and shaded areas. The ascospores are dark brown, unicellular, and measuring 11-15 μm in length. The fungus plays a role in decomposing organic matter and recycling nutrients in the ecosystem.
