Nervostroma, gen. nov. in the Sclerotiniaceae, the teleomorph of Cristulariella, and Hinomyces anam. gen. nov. to accommodate the anamorph of Grovesinia: reassessment of the genus Cristulariella

Taxonomy of the genus Cristulariella is revised, retaining Cristulariella (Crist.) depraedans as the type. Two new species, Crist. cercidiphylli and Crist. corni, are additionally described under the genus. The new anamorphic genus Hinomyces is erected to accommodate Botrytis (Cristulariella) moricola and Cristulariella pruni. A new genus and species, Nervostroma depraedans, is erected in the Sclerotiniaceae to accommodate the teleomorph of Crist. depraedans, with an additional species, Nervostroma cercidiphylli.
