Phaeolus schweinitzii

Schweinitzii root and butt rot

Description

Fruiting bodies are bulky, 10-30 cm wide, annual, growing commonly on both older and young trees from June until October. The surface is irregularly bumpy, finely pubescent, sulphur-yellow at first, later brownish orange, rusty-brown to blackish brown. The pores are sulphur-yellow, later greenish yellow, rusty to brown. Young fruiting bodies turn brown when pushed down. They do not grow in litterfall or mineral soil, instead they grow on decaying as well as on living roots, stumps and trunks. The mycelium causes intense red-brown heartwood rot producing a strong turpentine scent.
