The Pyrenomycetes constitute a large and generally well-marked section of the Ascomycetous Fungi. If we omit here the Perisporiales as an order by itself we may say of the Pyrenomycetes that there are perhaps 10,000 species, grouped in many genera, families, etc., but generally all set out in three suborders, the Sphariales, Dothideales and Hypocreales. The first two suborders named include by far the greater number of species and are in fruiting black, Pyrenos proper; the third suborder, the Hypocreales, have fructifications corresponding in structure to true Pyrenos but in color assume various tints red, yellow, etc., never black.
