The EXOBASIDIOMYCETES are a class of fungi sometimes associated with the abnormal outgrowths of plant tissues known as galls . The class includes Exobasidium camelliae Shirai, the camellia leaf gall and Exobasidium vaccinii Erikss, the leaf and flower gall. There are eight orders in the Exobasidiomycetes, including the Ceraceosorales , Doassansiales , Entylomatales , Exobasidiales , Georgefischeriales , Malasseziales , Microstromatales and the Tilletiales . Four of the eight orders include smut fungi . The families Ceraceosoraceae and Malasseziaceae were formally validated in 2009 for the orders Ceraceosorales and Malasseziales, respectively.
