Botrytis

Botrytis, a genus of Hyphomyceete Fungi (see FUNGI), containing many of the plants commonly called Mould and Mildew (q.v.). The silkworm disease known as Muscardine (q.v.) is caused by B. Bassiana. Some species have been identified as simply conidium-bearing forms of Ascomycetes, like Peziza and Sclerotinia.
