NOTES

The stromatal surface of the type specimen was said to be pinkish or reddish-white, and the interperithecial tissue to be composed of pale red or purple-red hyphae (Petch, 1924). We examined the Petch type which has a stromatal surface that has become so blackened that one can not discern its original color. Nonetheless, this material seems much like other cited collections. They all have light-colored granules not yielding pigments in 10% KOH solution and a dotted band along the germ slit.

Hypoxylon carneum is similar to H. vogesiacum in most characteristics except for its much smaller ascospore size range. The ascospore perispores of both taxa are variable in their dehiscence in 10% KOH solution among different specimens.
