Abstract

Trametes peckii is a heterothallic member of the Polyporaceae. The sex classes exhibit considerable irregularity, making any attempt to classify this organism as bipolar or tetrapolar highly questionable. Segregation of monosporous haplonts into "cottony" and "non-cottony" mycelia is clearly indicated. The dikaryotic secondary mycelium is always cottony, suggesting the possibility of the "dominance" of the cotton character. Repulsion between certain combinations of two mycelia of opposite sex groups, and the absence of repulsion between other pairs, resembles the phenomenon designated as "Barrage" by Vandendries. This fungus appears to exhibit three segregating characters; sex potentiality, haploid mycelial character, and repulsion.
