Ramularia didyma Unger 1833 var. didyma

Notes

Notes: There are three varieties of this species, namely R. didyma var. didyma [neotype on Ranunculus nemorosus,Switzerland, designated in von Arx (1983), in ZT], R. didyma var.exigua (holotype on Ranunculus uncinatus, USA, Oregon, WSP) and R. didyma var. pulsatillae [neotype on Pulsatilla pratensis, Denmark, designated in Braun (1998), in C]. While R. didymavar. didyma conidiophores emerge through stromata and formcatenate conidia, R. didyma var. exigua exhibits conidiophores erumpent through the cuticle, and R. didyma var. pulsatillae frequently forms solitary conidia. Ramularia didyma var. didyma has a wider distribution than the other two varieties (Braun 1998).
