 The genus "Ulocladium" was first discovered in 1851 by German mycologist, Preuss, in a small batch of his specimens.An abundant hyphomycetous growth of "Ulocladium" was found on a thin sliver of wood and was drawn and labeled by Preuss as "Ulocladium botrytis" in his manuscript.This sample was later acquired by the Botanisches Museum in Berlin.
