The process of spore formation on fruit-bodies of
Coprinus macrorhizus f.
microsporus developed by common-
B matings, e.g.,
AB×αB, was examined, making use of a gene marker,
f. The recessive gene
f controls the formation of undeveloped fruit-bodies and links neither of the incompatibility factors,
A and
B. Monosporous mycelia from the fruit-bodies produced by the common-
B matings, e.g.,
ABF×αBf, were analyzed for genetic constitution by pairing with two tester haplonts
abf and
Abf. Since, in most fruit-bodies, the progeny haplonts of the parental types,
ABF and
αBf, and those of the recombinant types,
Abf and
αBF, appeared in 1:1 ratio, it was presumed that karyogamy and meiosis precede regularly the formation of basidiospores with a few exceptions.
