(Doidge) Hughes, S. palicoureae (Farr) Hughes , S. ugandensis (Hansf.) Hughes are known from other parts of the country ( Hosagoudar 2003). From India, Schiffnerula canthii Hosag. & Archana on Canthium sp. and Schiffnerula braunii Hosag. & Sabeena on Morinda spp. are known on the members of the family Rubiaceae ( Hosagoudar & Sabeena 2010) . All these species are in their teleomorphs but the present fungus persists only in its Questieriella form. Hence, it has been accommodated in a new species.

Etyomology: Based on the host genus
