Leptoscyphus Mitten (1851: 358), a medium-sized genus of the Lophocoleaceae, is mainly distributed in tropical and temperate South America, Africa and Australasia, and is generally characterized by the brownish gametophyte colour and a laterally compressed perianth with a more or less bilabiate mouth due to the reduction of the ventral lobe (Vanderpoorten et al. 2010). 15 species are reported to occur in Ecuador (Gradstein & Benitez 2017). During revision of recent collections in the National Herbarium of Ecuador (QCNE) an undescribed species came to our attention which we here describe and illustrate.
