Abstract: The problem of the origin of species, more properly of "the splitting of an originally uniform species into several daughter species," (Mayr, 1963, p. 426) is one of the fundamental concerns of biology. Directly related to it are the principles of evolution, genetics, and ecology. Much of the recent literature in biology deals with species concepts and with the operant isolating mechanisms in various species. Dobzhansky (1951) has reviewed extensive work with Drosophila relative to the general principles of speciation. Mayr's classical work on evolution and species in general, Animal Species and Evolution, 1963, is well known. The Ascomycete Neurospora has been chosen as an experimental organism to investigate the occurrence of subspeciation for several reasons. It is ideal because of the relative technical ease with which laboratory cultures can be handled and its extensive use in experimental genetics. Also, strains of Neurospora from widespread geographical areas were easily available. Morten Lange, in The Fungi, Vol. Ill, (1968) cites lndefinlteness of the species concept in fungi and the lack of information from genetic studies using hybrids at the specific level. Srb (1959) reported studies involving crosses between strains of Neurospora from different geographical areas, but his emphasis was on demonstrating the cytoplasmic nature of the transmission of the Slow Growth trait in N. crassa.
