Type species – Stylodothis puccinioides (DC.) Arx & E. Müll., Stud. Mycol. 9: 11 (1975).
≡ Sphaeria puccinioides DC., Fl. franç., Edn 3 (Paris) 5/6: 118 (1815).
Notes – Stylodothis was introduced to accommodate S. puccinioides and S. indica (Thambugala et al. 2014a). Stylodothis is different from other genera in the family, in having 4–8 spored asci and ellipsoid to fusiform, brown, 1-septate ascospores (Thambugala et al. 2014a). Morphologically and phylogenetically Stylodothis is closely related to Dothidea (Thambugala et al. 2014a). Stylodothis puccinioides has 4 ascospores in ascus, while S. indica has 8 ascospores and sometimes with 2 or 3 septa (Thambugala et al. 2014a). A phylogenetic analysis by Schoch et al. (2006) showed S. puccinioides is closely related to Dothidea. We used only S. puccinioides for our phylogenetic analysis as it is the type species of Stylodothis. Nevertheless, members of the genus need recollecting, sequencing and epitypifying in order to confirm its generic status or family placement.
