The total number of species included in the orders under discussion is about 7200, distributed through 1818 genera. Some of the problems we have to confront can be exemplified by a particular example. In 1957 Holm defended a thesis in which he divided Leptosphaeria into segregate genera; that represented a revolution in the classification of this group of fungi. That genus is characterized by perithecioid ascomata, with a comparatively thick wall of scleroplectenchymatous cells, bitunicate asci, and brownish several-septate ascospores.
