These are distributed over the affected surfaces, and produce abundant conidia, which are hyaline, obovoidal, frequently trun- cated at the apex, measuring X 5-6/*. The conidia are appendaged, and they are expelled from the perithecium much as in the black rot of the grape. The ascogenous form is less com- monly found. In this the perithecia are much as those already described, except that the wall is denser and they bear only asci. The latter are more or less clavate, with a total length of from.
