Description edit
It is saprobic on wood, mostly beech. The semispherical lumps are up to 15 millimetres (5⁄8 in) wide and covered with 15–25 bumps in maturity. The flesh is hard and black.[1] Specimens are reddish when young, and they produce orange pigments when mixed with KOH.
Similar species edit
Similar species include Hypoxylon howeianum, which can be differentiated microscopically by smaller ascospores. The anamorph of H. fragiforme sits on a fuzzy green subiculum while the anamorph of H. howeianum sits on radiating hyphal cords, reminiscent of a white spiderweb-like structure.[2][3]
Other similar species exist within Annulohypoxylon, Nemania, and Rosellinia.[1]
