The first natural hybrids in the genus Phytophthora were described in 1998, and they were the result of hybridization between P. nicotianae and P. cactorum. They were described formally as Phytophthora × pelgrandis in 2009. In 2007 a second type of P. cactorum hybrid species was described, generated by hybridization between P. hedraiandra and P. cactorum; it is described formally here as P. × serendipita sp. nov. The morphological description of P. ×pelgrandis was incomplete and here we also add several important diagnostic characters of P. × pelgrandis that were not in its original description. In addition, ITS-SSCP profiles are presented confirming the hybrid identity of both P. × pelgrandis and P. × serendipita.
1998 年首次描述了 Phytophthora 属中的第一个天然杂种，它们是烟草疫霉和菜疫霉杂交的结果。2009 年正式将其描述为 Phytophthora × pelgrandis。2007 年，又描述了第二种类型的 P. cactorum 杂种，由 Hedra 疫霉和 P. cactorum 杂交产生；在这里正式将其描述为 P. × serendipita sp. nov。对 Phytophthora ×pelgrandis 的形态描述并不完整，在此我们还添加了其原始描述中未包含的几个重要的 Phytophthora × pelgrandis 诊断特征。此外，还呈现了 ITS-SSCP 图谱，证实了 P. × pelgrandis 和 P. × serendipita 的杂种身份。
