The all six isolates showed similar morphology each other, and had complexly branched secondary hyphae, globose non-proliferating sporangia and smooth surface oogonia which have one or two oospores per oogonium. The combination of these characteristics differentiated these isolates from the other known species of Pythium. Phylogenetic analyses based on sequences of the D1/D2 region of the large subunit ribosomal DNA showed that the all Pythium isolates were clustered in a single clade which distantly related from other known clades of the genus. We described these isolates as a new Pythium species, Pythium apinafurcum, based on morphology and molecular phylogeny. The P. apinafurcum isolates infected non-symptomatically the roots of seedlings of bermudagrass, cabbage and cucumber in a pot inoculation test.} }
