"Botryotinia" is a genus of ascomycete fungi causing several plant diseases. The anamorphs of "Botryotinia" are mostly included in the "imperfect fungi" genus "Botrytis". The genus contains 22 species and one hybrid.

Plant diseases caused by "Botryotinia" species appear primarily as blossom blights and fruit rots 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 takesplace with ascospores produced in apothecia, conidia are the means of asexual reproduction. Sclerotia of plano-convexoid shape are typical. Some species also cause damping off, killing seeds or seedlings during or before germination.

"Botryotinia fuckeliana" (or its anamorph "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".
