Abstract
The leafy liverwort genus Udaria D.K.Singh, S.Majumdar & D.Singh was recently described based on plants from Arunachal Pradesh and Sikkim in India. However, the name is a later homonym of Udaria A.Gupta, a fossil fungal genus discovered in Tertiary sediments of Dagshai and Subathu Formations in Himachal Pradesh, India. Hence, the liverwort genus is renamed here as Ramudaria, nom. nov. honouring the original eponym, Prof. Ram Udar. Its only species, Udaria lamellicaulis D.K.Singh, S.Majumdar & D.Singh is transferred to the newly named genus as Ramudaria lamellicaulis, comb. nov.
