Abstract Phytophthora ramorum (Werres, De Cock, Man in't Veld) is a heterothallic species. Initial pairing studies revealed that all European isolates were of A1 type while all American isolates were of A2 type. In 2003, a Belgian isolate was identified as a putative European A2 while some A1 isolates were reported in American nurseries, therefore suggesting some possible crossing between both mating types. However,attempts to produce oospores in vitro with classical methods were difficult compared to other heterothallic species, therefore suggesting a weak functionality of the sexual system in this Phytophthora species.
