On Eugenia sps. Molokai: Halawa, Aug. 1912, Forbes no. 477. The characteristics of this specimen differed slightly from the descrip- tion in that the center of the spot was white; the asci and spores larger, and the spores were cylindrical rather than fusiform. The spores from specimen Forbes no. 477 were wider than those of the printed description. In the light of these differences, it is possible that the fungus on the above specimens represents a new species..
