Status
The round, hard, spherical bodies may merge into larger blobs. The color ranges from gray-white, to rust, then black. There are other species of Hypoxylon that may be found in Maryland. Those not carefully keyed or verified by microscopic inspection are probably best placed on the Hypoxylon sp. page.
Relationships
Primarily (or perhaps only) found on American Beech.

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]
