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). [...]
In this article we will discuss about the features of homobasidiomycetidae. 1. Form large conspicuous fructifications called basidiocarps. 2. The septal pore is a complex dolipore septum with parenthesomes. 3. The basidium develops directly from a terminal cell of a dikaryotic hypha. 4. It is simple, unseptate, typically club-shaped or cylindrical. 5. With a few exceptions the basidium shows no [...]
