Sexual compatibility between serotypes ofFilobasidiella neoformans (Cryptococcus neoformans)

Twenty-five of 37Cryptococcus neoformans strains of known serotype produced the basidiomycetousFilobasidiella state either alone or when paired with a strain of compatible mating-type. Sixteen strains were “α” mating-type, four strains were “a” mating-type, and five strains were self-fertile.F. neoformans serotypes A and D were interfertile with compatible mating-types ofF. bacillispora serotypes B and C.C. neoformans var.gattii was interfertile with compatible mating-types ofF. neoformans andF. bacillispora. F. bacillispora strains, which utilized creatinine andl-malic acid, were interfertile with compatible mating-types ofF. neoformans, which did not utilize creatinine andl-malic acid. The interfertility between serotypes and biotypes eliminates the need for recognizing the names ofC. neoformans var.gattii, C. bacillisporus, andF. bacillispora. It is proposed thatC. neoformans var.gattii andC. bacillisporus be regarded as later, facultative synonyms ofC. neoformans and thatF. bacillispora be regarded as a later, facultative synonym ofF. neoformans.
