NOTES

The Ellis and Everhart type at NY contains two specimens numbered 26A and 26B. Specimen 26B is selected as the lectotype. Specimen 26A is H. polyporum.

Hypoxylon nicaraguense and H. polyporum are very similar in having peltate stromata, in having purplish stromatal pigments and in having a perispore not dehiscing in 10% KOH. They differ in that H. nicaraguense has darker ascospores and has a nearly spore-length germ slit. Further collections might show these two taxa to be conspecific. Hypoxylon symphyon is another similar fungus which differs from H. nicaraguense in having smaller ascospores and in having a germ slit less than spore-length and frequently on the flattened side of ascospores. Also compare with H. kretzschmarioides.
