Abstract

Some phenotypic and genotypic features of two toxigenic species representing the Petromyces genus, P. alliaceus and P. albertensis were examined. The conidial diameters of the strains were specific for the species examined. The isoenzyme patterns, carbon source utilization spectra, mitochondrial DNA and SmaI generated repetitive DNA profiles of the two species were almost identical. RAPD analysis revealed some species-specific amplified products, which made it possible to distinguish the two Petromyces species. However, the low level of variability observed indicates that these taxa belong to the same species.
