Abstract

Prosthemium betulinum and Pleomassaria siparia are found in the same sites on birch branches. Single spore cultures of P. siparia produced conidia similar to those of P. betulinum. Restriction analysis of 18S rDNA did not differentiate between P. betulinum and P. siparia. Random amplified microsatellite fingerprints showed a high amount of variation, which was not explained by the origin of cultures. We conclude that P. betulinum is the anamorphic state of P. siparia.
