Variability in Mating Behaviour and Culture Appearance of Lenzites trabea
Forest Products Laboratory, Division of Building Research, CSIRO Melbourne, Australia
Received: 16 June 1972
Twenty-three homokaryons of Lenzites trabea (Pers.) Fr. were produced, mainly by chemical monokaryotization, from dikaryons isolated from widely separated regions throughout the world. These homokaryons possessed 18 different mating factor alleles, so an estimate was made of the total number of alleles in the world population of 51, 45, or 36, depending on the method of estimation. Some variability in the production of clamp connections during mating was noted. It was also found that the appearance of the cultures varied considerably, especially that of the homokaryons. A brief study was made of this variability on several culture media, and the appearance of dikaryons and their constituent homokaryons was compared on malt agar.
