'''''Botryotinia''''' is a [[genus]] of [[ascomycete]] [[fungi]] causing several plant diseases. The [[anamorph]]s of ''Botryotinia'' are mostly included in the ''[[Deuteromycetes|imperfect fungi]]'' genus '''''Botrytis'''''. The genus contains 22 species and one hybrid.
Plant diseases caused by ''Botryotinia'' species appear primarily as blossom [[blight]]s and fruit [[rot]]s but also as leaf spots and bulb rots in the field and in stored products. The fungi induce [[host cell]] death resulting in progressive decay of infected plant tissue, whence they take nutrients. [[Sexual reproduction]] takes
place with [[ascospore]]s produced in [[apothecium|apothecia]], [[conidia]] are the means of [[asexual reproduction]]. [[Sclerotium|Sclerotia]] of plano-convexoid shape are typical. Some species also cause [[damping off]], killing seeds or [[seedling]]s during or before [[germination]].
''[[Botryotinia fuckeliana]]'' (or ''Botrytis cinerea'') is an important species for [[wine]] industry as well as horticulture.
Other economically important species include ''[[Botryotinia convoluta]]'' (the [[type species]] of the genus), ''[[Botryotinia polyblastis]]'', ''[[Botrytis allii]]'' and ''[[Botrytis fabae]]''.
