Three new taxa of Peronospora described from Bulgaria are revised: P. jordanovii is invalid and the type not extant, P. parietariae is most probably based on contaminated material, and P. knautiae var. longispora is apparently based on two fungi but only P. knautiae var. knautiae is present in the holotype. The presence in Bulgaria of Plasmopara on Geranium is not confirmed.

Of the 83 specimens of Peronosporales collected in the north-eastern part of Bulgaria in 1998 and 1999, and some 16 specimens collected earlier and present in herb. BUCM, two genera (Basidiophora and Bremiella), 6 species (Basidiophora entospora, Bremiella baudysii, Peronospora affinis, P. holostei, P. medicaginis-minimae, and Pseudoperonospora cannabina), and 32 fungus-host combinations are for the first time reported from this country. In addition, 30 new localities for previously known such combinations are included.
