Septoria passerinii is known only from its anamorphic Septoria state; no teleomorph has been identified. In culture, S. passerinii looks very similar to Mycosphaerella graminicola from wheat. Comparisons of the nucleotide sequences of the internal transcribed spacer (ITS) regions of the ribosomal DNA of both species and of many other fungi in the Dothideales revealed that the ITS regions of S. passerinii and M. graminicola differed by only 10 bases out of 571 total. Therefore, these species are very closely related. Phylogenetic analysis showed that S. passerinii and M. graminicola grouped together within a large cluster of Mycosphaerella species. Thus, S. passerinii almost certainly has a Mycosphaerella teleomorph.
