The parasitic genus Endodothiora was introduced to accommodate a single species E. sydowiana Petr., which is immersed in ascostromata of Dothidea puccinioides (Barr 1972). This genus is placed in Dothioraceae based on its parasitic nature on Dothidea collecta, and also immersing in the stroma of the host fungus. Poly-spored asci and multi-septate hyaline ascospores of Endodothiora share similar with those of Sydowia, but the immersed parasitic habitat excludes it from Sydowia (Barr 1972, 2001). Thambugala et al. (2014a) re-examined the type and found different asci with brown ascospores (Dothidea puccinioides) which share the same ascomata that is good proof for E. sydowiana being parasitic on Dothidea puccinioides. Other major sexual morph characters of this genus are subglobose to broadly ellipsoid, coriaceous ascostromata with 2–5 locules, cylindrical to broadly cylindrical asci and oblong, multi-septate ascospores which are constricted at the primary septum. The asexual morph is unknown (Thambugala et al. 2014a). Further investigations of its morphology and DNA based analysis are suggested.

Type species: Endodothiora sydowiana Petr., Annls mycol. 27(5/6): 345 (1929).

Other accepted species: Species Fungorum – search Endodothiora.
