The following points highlight the twenty salient features of agaricus. 1. The primary mycelium produced by the germination of basidiospores is of short duration. It consists of cells each with a haploid (n) nucleus (A). 2. Soon as a result of hyphal fusions of compatible strains, a binucleate condition established in one of the cells of the primary mycelium (B). [...]
