Isolates of Diplodia macrospora, D. natalensis, D. zeae, Botryodiplodia hypodermia, B. theobromae, Physalospora rhodina, Botryosphaeria ribis, and a Sphaeropsis sp. were grown on synthetic agar media supplemented with 23 carbon sources used either singly or in combination. Taxonomic criteria currently used to delimit these species differed, in most of the isolates, with the carbon sources tested. Results indicate the need for additional studies to establish standard culture conditions for use in taxonomic considerations of these fungi.
