Laetiporus sulphureus
Sulphur fungus rot
Large shiny fruiting bodies are visible from a distance. The pileus surface is orange yellow; the porous underside is sulphur-yellow. The flesh is soft and crumbly, white to yellowish when dry. The mycelium causes brown prismatic rot of butts of living broadleaves and conifers, and also on tree stumps and dead trees and branches. White felt-like mycelial residues are striking in cracks of rotting and shriveling up wood. It is an edible fungus; in England known also as “forest chicken meat”.
