NOTES

Hypoxylon olivicolor is distinctive among taxa of section Hypoxylon with bright red or orange red granules in having an olivaceous stromatal surface. Among taxa of section Hypoxylon with an olivaceous stromatal surface, Hypoxylon olivicolor differs from H. papillatum in having bright granules, in having smaller, inequilateral ascospores, and in having a dehiscent perispore. It differs from H. dingleyae in having bright granules, in having smaller ascospores, and in having a spore-length germ slit. It differs from H. musceum in having bright granules and having a spore-length germ slit.

Hypoxylon viridicolor P. Martin was described by Martin (1969a) as having an olive green stromatal surface. Unfortunately, we were unable to locate his type material. According to Martin's description, Hypoxylon viridicolor is different from H. olivicolor in having yellow green granules, and in having a Virgariella-like conidiogenous structure.
