Ho, H.H., M.E. Gallegly & C.X. Hong. Redescription of Phytophthora melonis. Mycotaxon 102: 339-345. 2007.

ABSTRACT: Phytophthora melonis was erected by Katsura (1976) to accommodate the causal agent of foot rot of cucumber in Japan. It was characterized by the production of semipapillate sporangia and chlamydospores. However, a reexamination of the type culture and other isolates from cucurbits showed that the sporangia are nonpapillate with internal proliferation, and chlamydospores are absent. The species is hereby redescribed to facilitate accurate identification of P. melonis.
