Pleurotus pulmonarius

Pale oyster

Description

The pileus has a diameter of 60-250 mm, first almost semi-globular, later vaulted to almost flatly spread out, grey, greyish brown to brown, smooth, naked, folded on the edge when young. Gills are 6-12 mm wide, thick, white to greyish, deeply converging onto the stem. The stem is out-of-centre or lateral, 10-30 mm long and 10-40 mm thick, white or greyish, almost all covered with converging gills, hairy on the base. The fruiting bodies occur almost always in plentiful clusters from summer to winter. The mycelium causes white rot.
