Abstract:This present paper deals with a new species and a new record of the genus Albugo reported. The specimen of Albugo eomeconis Zhang et Wang sp.nov. is parasitic on the leaves of Eomecon chionantha Hance (Papaver- aceae) from Sichuan Province. This species is closely related to Albugo macro- spora (Togashi) S.Ito., but may be distinguished from the latter by its sm-a ller conidia and parasitic on Papaveraceae, not on Cruciferae. The type specimen that is described and discussed ill this paper is deposited in the Her- barium of Agricultural University of Yunnan. The another species new to China, Albugo capparidis (de Bary) Cif. parasitic on the leaves, stems and fruits of Cleome gynandra L. and Cleome viscosa L. (Capparidaceae). They are dis- tributed in Yunnan and Guangxi Province.
