Botrytis

 

Species of Botrytis produce coarse, brown conidiophores with branched tops. The spores (conidia) cover the ultimate branches and are produced synchronously. As the colonies begin to dry, the cells of the conidiophore often flatten in alternate planes from each other. Many isolates produce black stone-like sclerotia. Often isolated from dead or living plants and frequently causing plant disease. Holomorphs: Botryotinia, Ciboria, Sclerotinia. Ref: Ellis 1971; Hennebert 1973
