The genus is a very large one similar to Phoma and Phyllosticta except in its spore form and in the ostiole which is frequently very large. Septoria and Phleospora are distinguished only by the lesser development of the walls of the latter and many species which in early stages pass as Phleospora would in older stages be classed as Septoria. Septoria and Rhabdospora are distinguished only by the part of the host affected, stem or leaf, and many forms in

These are exceedingly variable, sometimes large, and multiseptate, at other times minute, resembling sper- matia. In such genera as are chiefly epiphytal, in Septoria, Phyllosticta, and their allies, the minute spores are enclosed within membranaceous perithecia, and when mature these are ejected from the orifice at the apex, or are exposed by the break- ing off of the upper portion of the perithecia.
