Abstract

Three hundred and seventy mutants of the ascomycete stock were isolated. They were assigned to at least 75 loci. Mutations in 33 loci affect ascospore morphology: 19 of these loci affect pigmentation, 5 affect pigment distribution and 9 affect shape. The reliability of various phenotypes and the role of multigenic control on ascospore morphogenesis are discussed. Other mutations affect the mycelial growth rate or morphology and sporulation. A total of 56 loci have been mapped in 13 linkage groups corresponding to at least nine chromosomes. Using an intermediary strain, successful crosses between two intersterile stocks of ( and ) demonstrated that 12 pairs of mutants isolated in each stock correspond to 12 homologous loci.
