| Summary: | The plant nursery industry has become an ideal reservoir for <i>Phytophthora</i> species and other soilborne pathogens. In this context, isolation from tissues and soil of ornamental and forest plants from nurseries in four regions of Spain was carried out. A high diversity of <i>Phytophthora</i> species was confirmed. Fourteen <i>Phytophthora</i> phylotypes (<i>P. cactorum</i>, <i>P. cambivora</i>, <i>P. cinnamomi</i>, <i>P. citrophthora</i>, <i>P. crassamura</i>, <i>P. gonapodyides</i>, <i>P. hedraiandra</i>, <i>P. nicotianae</i>, <i>P. niederhauserii</i>, <i>P. palmivora</i>, <i>P. plurivora</i>, <i>P. pseudocryptogea</i>, <i>P. sansomeana,</i> and <i>Phytophthora</i> sp. tropicalis-like 2) were isolated from over 500 plant samples of 22 species in 19 plant genera. Nine species were detected in water sources, two of them (<i>P. bilorbang</i> and <i>P. lacustris</i>) exclusively from water samples. <i>P. crassamura</i> was detected for the first time in Spain. This is the first time <i>P. pseudocryptogea</i> is isolated from <i>Chamaecyparis lawsoniana</i> and <i>Yucca rostrata</i> in Spain.
