    Phytophthora tentaculata Kröber & Marwitz was described in 1993 in Germany on greenhouse-grown nursery ornamentals. It has since been found in Italy, Spain, China and the U.S. (California) causing a root and stem rot of many different plant species including nursery-grown native species used for habitat restoration. P. tentaculata is homothallic and is classified in Stamps group I which is characterized by the production of mostly paragynous antheridia, papillate sporangia and the production of both hyphal swellings and chlamydospores in culture. P. tentaculata is placed in phylogenetic Clade 1 (Cooke et al., 2000) with species such as P. cactorum, P. nicotianae, P. clandestina, P. iranica, P. hedraiandra and P. pseudotsugae.
