Botrytis and Botrytis-like genera.

Abstract

Critical revision of Botrytis-like genera leads to recognition of Botrytis, Chromelosporium, Glischroderma and Ostracoderma. Phymatotrichum is synonymized with Botrytis, and previously assigned species are reconsidered. Six new genera are recognized: Pulchromyces (for Phymatotrichum fimicola Dring); Phymatotrichopsis (for Phymatotrichum omnivorum Duggar); Streptobotrys, Amphobotrys, and Verrucobotrys (for conidial states of the Sclerotiniaceae); Dichobotrys (for the conidial state of Operculate Discomycetes of the genus Trichophaea).\nHyphelia terrestris Fr. and related species, including conidial states of some Operculate Discomycetes of the genus Peziza, are placed in Chromelosporium. Peridiate fungi with a similar conidial apparatus, described in Lycoperdellon, are transferred to Ostracoderma, while Glischroderma is kept distinct.\nThirteen new species are proposed, and 16 new combinations are made for the species discussed.
