Abstract

Coprinus sterquilinus, a homothallic Hymenomycete, has a typical diploid nuclear cycle i.e., nuclear fusion occurs in the basidium, followed by the formation of a nuclear tetrad and four spores. Each spore receives one nucleus which divides at least once. The chromosomes are too small and poorly defined to use the chromosome count to establish the time and place of meiosis, but the fact that each spore, though receiving but one nucleus, carries the full complement of sex factors, suggests that disjunction of sex factors does not occur in the basidium. Disjunction, and possibly numerical reduction may be delayed until nuclear division in the spore.
