Phytophthora borealis and Phytophthora riparia, identified in recent Phytophthora surveys of forest streams in Oregon, California and Alaska, are described as new species in Phytophthora ITS Clade 6. They are similar in growth form and morphology to P. gonapodyides and are predominantly sterile. They present unique DNA sequences, however, and differ in temperature/growth relations and geographic distribution.
在最近对俄勒冈州、加利福尼亚州和阿拉斯加的森林溪流中的疫霉属进行的调查中，鉴定出北方疫霉和里帕里亚疫霉，它们被描述为 ITS 聚类 6 中的新种。它们在生长形态和形态上与瓜果疫霉相似，且主要是不育的。然而，它们具有独特的 DNA 序列，在温度/生长关系和地理分布上存在差异。
