Ganoderma acontextum

Ganoderma acontextum is a small, hard, hoof-shaped perennial bracket described in 2022 from Guatemala, also found on oak in Virginia. Its dull reddish-brown cap is densely furrowed and the flesh is extremely thin, which gives it its name. It is known from three collections, so conditions come from those places and the genus.
