The Family Sclerotiniaceae consists of a diverse group of fungi that are economically and ecologically important. This family includes the well-known genera Sclerotinia, Botrytis, and Monilinia. The family is characterized by the presence of hard, compact, darkly pigmented structures called sclerotia, which form on infected plant tissue. The sclerotia are essential for the survival of the fungus during adverse environmental conditions, such as cold winters or dry summers. Synonyms for the Family Sclerotiniaceae include the Botrytis family, Moniliaceae, and Sclerotiniales. Understanding the taxonomy of this family is important for plant pathologists and fungal ecologists, as well as those involved in crop protection and management.
