Phytophthora fragariae var. rubi is now considered as a distinct species: Phytophthora rubi

Phytophthora fragariae (EPPO A2 List) was originally described as the causal agent of red core of strawberry (Fragaria ananassa). Later, morphologically similar isolates were obtained from raspberry plants (Rubus idaeus) affected by root rot, and it was considered that strains from strawberry and raspberry could be separated into two varieties of P. fragariae: P. fragariae var. fragariae and P. fragariae var. rubi, respectively. Recent studies have demonstrated that Rubus idaeus strains constituted a separate and distinct species, Phytophthora rubi comb. nov.
