Taxonomy

The species was originally described as Boletus resinosus in 1794 by German botanist Heinrich Schrader. It has acquired an extensive synonymy in its taxonomic history, having been juggled between several genera. Petter Karsten transferred it to Ischnoderma in 1879 to give it the name by which it is currently known.[2]

Description

This shelf mushroom is 7–30 cm (3–12 in) across,[1] velvety, dark red/brown, darkening and forming zones in age.[3] The whitish to brownish flesh is watery when young and corky with age.[1] It is sweet smelling.

Ischnoderma benzoinum is similar and has darker flesh.[3]

Habitat and distribution

This fungus fruits on hardwood logs and stumps in autumn.[4] A widely distributed species, it has been recorded from Africa, Asia, Europe, and North America.[5]

Uses

Young, soft specimens may be cooked and eaten, but the species becomes hard and unpalatable in age.[6]
