synonyms

Claviceps microcephala (Wallroth) Tulasne, 1853. Pažoutová ao (2000a) have demonstrated that within the species C. purpurea three, not sharlpy defined, chemo-races do exist, growing on a wide variatie of grass species, in moderately dry, wet, and brackish vegetations, respectively. This eliminates the basis for (among others) microcephala as a separate species. C. sesleriae Stäger, 1906, is cited as a synonym of purpurea by Pažoutová (2002a).

notes

Buhr (1964b) and other authors do not consider C. purpurea a true gall. Indeed does the sclerotium entirely consist of fungal tissue, therefore isn’t a gall. But the malformation of the inflorescence that occurs at least under strong infestation certainly is a gall.

parasites

Neobarya aurantiaca.
