Status anamorphosus: Chaetopsina cf. fulva Rambelli, Atti Accad. Sci. Bologna 15: 5.1956.

NOTES. Conidiophores formed in culture paralleled those found nature except that in nature phialides were strictly terminal whereas culture they were either terminal or intercalary. Cultures were made from ascospores isolated from both of the collections cited above; unfortunately these cultures have been lost. Dried cultures are deposited with the specimens deposited in PDD.
