The Genus Sclerotium is composed of a group of fungi that are commonly known as "sclerotial fungi" due to their characteristic sclerotia structures. These fungi produce hard, compact masses of hyphae that serve as survival structures during adverse environmental conditions. The Genus Sclerotium includes several species, such as Sclerotinia, Botrytis, and Rhizoctonia, among others. Depending on the context, these different genera can be used as synonyms for the term "Genus Sclerotium." In agriculture, for example, Rhizoctonia is of special interest due to its ability to cause economically significant diseases in various crops. Despite their distinct scientific names, all of these fungi share similar features and ecological roles as sclerotial fungi.
