Ramularia primulae Thüm., 1878 (an anamorphic fungus)

Notes (MWS) Ellis & Ellis (land Plants) describe conidia as "mostly 0- or1-septate" but illustrate them as 0- to 2-septate.
Diagnostic features There are two species of Ramularia on Primula spp.: this and R. interstitialis. They differ in the conidia being 0-2 septate and 6-40/3-5µm in the present species, and 0-septate, 9-20/5-8µm in R. interstitialis.

Perhaps the commoner species on Primula veris?
