Mutations have been detected which affect the production of protoperithecia in Sordaria brevicollis. These mutations have been called perithecial-1 and perithecial-2. Ascus analysis revealed that the former was a centromere unlinked gene, whilst the latter was very close to the mating-type locus. The per 1−per 2− genotype was female sterile. Recovery of fertility by a sterile culture occurred and perithecial analysis revealed that this recovery was due to the accumulation of revertant per 1+ nuclei in the mycelium. Per l−per 2+ colonies were fertile and gave a cross of characteristic appearance.
