Interpretive Summary:

Technical Abstract: We can define evolutionary species of Phytophthora as populations that share a single most recent common ancestor and have maintained genetic similarity in morphology, physiology, and ecological behavior. The theory is straightforward, the practice is not so easy. Three current challenges to our species concept are presented, including the working group’s input delivered at the Conference and most recent publications involving these species/groups.
