Bjerkandera adusta

Smoky bracket

Description

The caps are mostly arranged roof-like, one above the other. First they are softly prickly, ochre-grey, always with a white edge when young. The pores are irregular, whitish, when pushed they change their colour to greyish brown, later grey to greyish black. The fungus is a saprophyte on dead branches, trunks, and stumps. It can become a parasite when the wounded trunk is infected. The mycelium causes intense white rot of the attacked wood, mostly of heart wood. The mycelium activity in wood can result in drying of the crown and reducing of trunk strength. The fungus is spread from lowlands to mountainous regions.

The presence of light gray caps of fruiting bodies.
