sp. nov., a New Species Causing Foliage Spot of Rubber Tree in China.

A new species of causing leaf spots on the rubber tree () in Yunnan, China, was isolated, examined, and illustrated. Morphologically, it belongs to the section of , which produces relatively large conidia and a simple or branched, filamentous long beak. It is, however, characterized by conidiophores gradually enlarging near the apex into a clavate conidiogenous cell and long ellipsoid to obclavate, smooth-walled conidia with a long filamentous beak. Molecular phylogenetic analyses based on , , and sequences demonstrate that the phytopathogen falls in the clade of the section , being most closely related to , , , , , and .
