Abstract
The earlier studies on the genetics of Sordaria fimicola (Olive, 1956) were begun with the object of establishing a procedure for ordered tetrad analysis in a homothallic species. This was accomplished by first obtaining spore-color mutants by ultraviolet irradiation. Any of these mutants when paired with wild type would yield some perithecia containing hybrid asci, visibly recognizable by their four dark wild-type and four lighter mutant spores (Figure 1). As in the 8-spored ascus of Neurospora, the products of meiosis are found in an orderly series representing an exact account of meiotic segregation. Since S. fimicola is a homothallic species in which any haploid nucleus in the mycelium is compatible with any other nucleus, selfed perithecia are produced abundantly along with the hybrid ones. Indeed, some clusters of asci from a single perithecium may contain both hybrid and homozygous asci.
