Taxonomy
Intrageneric Specialization (f. helianthi)
According to the European and Mediterranean Plant Protection Organization (EPPO), the intragenus specialized taxon "f.helianthi" was introduced by (Novotel'nova, 1966) in Russia[3].
The EPO also claims that the taxon "appears to be invalid for regions use outside of Krasnodar area of Russia"[3], according to (Sackston, 1981; Virányi, 1984), and that it remains to be determined whether a specialized fungus as described by (Novotel'nova, 1966) exists in other regions.[3]
