Summary:During 2002, in ornamental nurseries in Corrientes (27°31' S lat., 55°60' W long.), Argentina, plants of Philodendron scandens subsp. oxycardium , affected by leaf spots were observed. Macroscopic and microscopic examinations, and isolation of the fungus associated with the symptoms were performed. Based on culture studies , morphometric characteristics and the pathogenicity tests, the fungal agent was identified as Phytophthora capsici Leonian. This is the first report of P. capsici affecting plants of P. scandens subsp. oxycardium in Argentina. Durante el año 2002, en viveros ornamentales comerciales de Corrientes (27°31' lat. Sur, 55°60' long. Oeste), Argentina, se observaron plantas de filodendro, Philodendron scandens subsp. oxycardium , que presentaban manchas foliares. Se realizaron observaciones macroscópicas, microscópicas y aislamientos en cultivo del hongo relacionado con los síntomas observados. En base a las características culturales, morfométricas y pruebas de patogenicidad, el agente causal fue identificado como Phytophthora capsici Leonian. Esta es la primera información de P. capsici afectando plantas de P. scandens subsp. oxycardium en la Argentina.
