摘要

Three new species of Pythium: P. ershadii, P. pyrioosporum, and P. urmianum from soils of various regions in Iran are described and illustrated. These species are morphologically distinct from all other known species. Pythium ershadii is morphologically characterized by pyriform ornamented oogonia and rarely production of pyriform oospores. Pythium pyrioosporum differs from other species of the genus by the production of pyriform oospores and smooth walled oogonia, oospores with a tapering elongation toward a hypogynous antheridium and intercalary hypogynous antheridia. Pythium urmianum is distinguished by the presence of intercalary hypogynous antheridia, smooth walled oogonia formed laterally on hyphae or on short side branches and peanut-shaped oospores. Phylogenetic relationships of these new taxa with other Pythium species were investigated using internal transcribed spacers rDNA and partial coxl sequence data. The three species reside in Glade El and are separated from closely related species.
