Abstract: A detailed description of Hydropisphaera heliconiae sp. nov. is presented based on two collections on dead leaves of Heliconia caribea (Heliconiaceae) in Martinique (FWI). The fungus was cultured and sequenced and its placement in the genus Hydropisphaera confirmed by analysis of LSU sequences. This species primarily differs from all known species in having ascomata nearly black when mature and deeply cupulate when dry. The new combination Ijuhya boothii is proposed for a taxon examined during this study that was formerly placed in Hydropisphaera
In continuation of a research program on the fungal diversity of the Lesser Antilles (Lechat & Fournier, 2017), we collected a surprising species of Hydropisphaera (Tode: Fr.) Dumort. with blackish and deeply cupulate ascomata occurring on dead leaves of Heliconia caribea Lamb. Usually, the ascomata of Hydropisphaera are pale yellow [...]
