Abstract:
The ascospore septation in 13 species ofDiploschistes was examined. Microcephalic, macrocephalic, as well as irregular ascospore septation were found. In some species and even specimens of some species, different types of spore septation were detected. The taxonomic significance of the character of ascospore septation sequence is questioned, and the distinction of the ordersGraphidales andOstropales, which was primarily based on this character, is rejected.
