A genus of fungi in the subphylum Imperfectomycetes and class Imperfectomycetes. It lives saprophytically, but parasitizes many plants as the cause of gray mold. The conidiophores branch sparsely at the top, and several conidia are formed from the tips by budding. Although it is an imperfect fungus, a sexual form (perfect form) is also known, and the sexual form is considered to be in the genus Botryotinia in the Ascomycetes, Discomycetes, and Scleractinaceae family. It is a pathogen distributed worldwide, causing great damage to strawberries, tomatoes, eggplants, mandarins, and other plants. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
