Abstract
The ascospore septation in 13 species of Diploschistes was examined. M icrocephalic, macrocephalic, as well as irregular ascospore septation were found. In some species and even specimens of some species, differ ent types of spore septation were detected. The taxonomic significance of the character of ascospore septation sequence is questioned, and t he distinction of the orders Graphidales and Ostropales, which was pri marily based on this character, is rejected.
