Sporocadus was introduced by Corda (1839) to accommodate four species (Spo. herbarum, Spo. georginae, Spo. lichenicola, and Spo. maculans), but no generic type was designated (Corda 1839). Hughes (1958) provided a lectotype based on Spo. lichenicola. Sutton (1975) synonymized Sporocadus under Seimatosporium. Brockman (1976) and Nag Raj (1993) did not agree with Sutton (1975) and treated Sporocadus as distinct from Seimatosporium. In the phylogenetic analysis of Liu et al. (2019), Sporocadus formed a distinct lineage with Seimatosporium hence Sporocadus was resurrected and epitypified by Spo. lichenicola. Sporocadus is characterized by 3-septate, fusoid, cylindrical and obovoid conidia lacking appendages. Two species S. trimorphus and Spo. rosarum are exceptions as they produce both non-appendaged and appendaged conidia. Sporocadus can be differentiated from Seimatosporium based on DNA sequence data. In this study, we provide a geographical record for Sporocadus sorbi from Uzbekistan. The latter was introduced by Wijayawardene et al. (2015) as Seimatosporium sorbi. Liu et al. (2019) provided the combination Sporocadus sorbi.
