Hypoxylon fragiforme is a multiperitheciate carbonaceous pyrenomycete known from Europe and North America.
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]
