Doassansiopsis tomasii Vanky, recently described as a new species from infected leaves of Nymphaea nouchali Burm.f. in Ethiopia, is reported from the second world locality in Uganda. In this country it was found in Lake Victoria on Nymphaea sp. 52 years earlier than the type specimen in Ethiopia. The sori and spore balls of D. tomasii are described and illustrated by line drawings, LM and SEM micrographs, and the global distribution of the smut fungus is presented on the map. In addition, an interesting case of accidental infection of Nymphaea nouchali by Doassansiopsis nymphoides Vanky in Zambia is briefly discussed.
