Trametes gibbosa

Lumpy bracket

Description

Fruiting bodies are perennial, 8–15 cm wide, laterally attached, semicircular. The surface is flat, only at the point of attachment slightly convex with a characteristic lump, sparsely striped, slightly grooved and covered with thick thorny hair. When young, its surface is white, then greyish, also greyish green under the influence of algae, and almost black when old. Pores are elongated. The fruiting bodies are often consumed by beetle larvae, as evidenced by the grains of the fungus around the fruiting body. The mycelium causes quite intense white rot of attacked wood.
