Notes on taxonomy and nomenclature
Ceratocystis fimbriata, the type species of the genus, was originally described on sweet potato (Ipomoea batatas) in 1890 (Halsted, 1890). Saccardo (1892) transferred the species to Sphaeronaema, Elliott (1923) transferred it to Ceratostomella, Melin and Nannfeldt (1934) transferred it to Ophiostoma, and Davidson (1935) transferred it to Endoconidiophora. Placement in Ceratocystis has been accepted since 1950 (Bakshi, 1950).
