Stereum subtomentosum
Yellow curtain crust
Fruiting bodies are laterally attached to wood. The cap is 3-7 cm wide, thin, pliable, concentrically striped, when young it is covered with low felt, mostly greyish orange, when old it is commonly covered with green algae. On the fertile side it is smooth, greyish yellow to brown ochre. When wet, it turns yellow at wounded places. From similar Stereum hirsutum it is distinguished by the yellowing of damaged pulp and by the underdeveloped stem, or at least by its sign (by narrowing of fruiting bodies at the base attaching to wood). The mycelium causes intense white rot of sapwood.
