Ascus, Ascus ultrastructure, Ascus wall
The ultrastructure of the ascus wall of five free-living and two lichenized Ascomycetes is briefly described. The unitunicate ascus is interpreted to be two layered, and the bitunicate ascus is interpreted to be four layered. It is suggested that the terms "single layered" and "two layered" not be used synonymously with the terms "unitunicate" and "bitunicate" respectively.
