Substantial difficulties in the morphological identification of phoma-like fungi, including Paraphoma spp., have resulted in poor understanding of the generic and species boundaries in this group of organisms. This study was devoted to the reidentification and taxonomic revision of phoma-like isolates derived from Convolvulaceae leaves collected from different geographical locations in Russia and territories of neighboring countries. The study was based primarily on sequencing phylogenetically informative loci (ITS, LSU, TUB, and RPB2) and on traditional morphological approaches. The resulting phylogenetic tree revealed three well-supported monophyletic clades, corresponding to three Paraphoma species. The new species Paraphoma melnikiae Gomzhina M. M. & Gasich E. L. was described, and a new taxonomic combination, Paraphoma convolvuli (Dearn. & House) Gomzhina M. M. & Gasich E. L., was established for Stagonospora convolvuli. Several isolates were preliminarily identified as Paraphoma cf. convolvuli and are likely new species of the genus Paraphoma, but this requires further verification.

与旋花科相关的副噬菌种

phph -like真菌，包括Paraphoma spp。，在形态学鉴定上存在很大的困难，导致人们对这组生物体的种属和物种边界了解不足。这项研究致力于从旋花科叶片中分离出的噬菌斑状分离物的重新鉴定和分类学修订，这些叶状分离物来自俄罗斯不同地理位置和邻国领土。该研究主要基于系统信息学基因座（ITS，LSU，TUB和RPB2）的测序，并基于传统的形态学方法。所得的系统发育树显示了三个支撑良好的单系统进化枝，对应于三种副噬菌种。新物种Paraphoma melnikiae Gomzhina MM＆Gasich EL进行了说明，和一个新的分类组合，Paraphoma天蛾（Dearn。＆楼）Gomzhina MM＆Gasich EL，建立了Stagonospora天蛾。一些菌株被初步鉴定为Paraphoma比照 甘薯天蛾并属可能新物种Paraphoma，但这需要进一步的验证。
