Pseudopezicula tracheiphila, the causal agent of Rotbrenner on grapevi
nes (Vitis vinijera), appears to be composed of two mating types which
exhibit a bipolar heterothallic system. The development of apothecia
in vitro is possible with crosses of two different compatible strains
of the fungus on sterilized grape leaves.
