SINGH Mycology Laboratory, Department Of Botany, D.D.U. Gorakhpur University, Gorakhpur 273 009 ABSTRACT: This paper includes 3 new species of hyphomycetous genus Phaeoramularia Munt. Viz., P. dicanthii-annulatae, P.erigeronis and P. rosigena collected on living leaves of Dicanthium annulatum, Erigeron asteroides and Spiraea bella respectively. They are compared with allied taxa, particularly those occurring on same host genus or on the host family. Keywords: Hyphomycete, Foliicolous, Phaeoramularia , new species Some foliicolous fungi were collected from N0i1hEastern U.P. the examination revealed three undescribed species of hyphomycete genus Phaeoramu/aria Muntanola (1960). MATERIALS AND METHODS Leafsamples showing distinct symptoms were collected in separate polythene bags. These were broughttothe laboratory for herbarium preparation. Suitablemounts were examined and camera-Iucida drawings prepared so as to show the most diagnostic characters.
