The "Phytophthora" pathogens in strawberry and raspberry are similar in many ways morphologically, culturally, and molecularly, but are different in growth. Nonetheless, they are both variations of the pathogen "P. fragariae". Recent research, however, suggests that these two variations may not have been as similar as once perceived. A study done to genetically map these pathogens revealed such a difference in the genome of these two variations, they likely could be considered two completely different species. This research has yet to make any changes to the present day cytology and taxonomy of this pathogen.
