Note on some Peronosporales described from Bulgaria

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.
