Ramularia primulae (an anamorphic fungus) may be included in identification literature listed under the following higher taxa:

NBNNBN (data.nbn.org.uk) has a distribution map for Ramularia primulae (an anamorphic fungus)
BioInfoBioInfo (www.bioinfo.org.uk) has 11 host/parasite/foodplant and/or other relationships for Ramularia primulae (an anamorphic fungus)

Ellis & Ellis (land Plants) describe conidia as "mostly 0- or1-septate" but illustrate them as 0- to 2-septate.

There are two species of Ramularia on Primula spp.: this and R. interstitialis.

The present species causes discrete brown spots while R. interstitialis causes diffuse yellowish patches on the leaf surface.

They also 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.
