Abstract: | Compatible monokaryotic strains of Agaricus bisporus ATCC 36975 and 36976 and the resulting dikaryon of their mating were grown in a liquid medium, and their respective cell
walls were prepared. Significant differences were not found in the gross chemical composition of the three hyphal types. However,
the neutral carbohydrate composition of the complete walls and their fractions was found to be somewhat different in each
strain. More consistent differences were encountered in the chemical structure of the distinct polysaccharidic wall fractions
in the three types of organisms. Some of these structural wall differences can be considered as characteristic markers for
differentiating the mono- and dikaryotic types of A. bisporus.
