Résumé (anglais) : Varicosporellopsis aquatilis gen. and sp. nov. is described and illustrated based on two collections on submerged wood in southern France. An acremonium-like asexual morph was obtained in culture and sequenced. The genus is placed in the Nectriaceae based on its asexual morph and phylogenetic comparison of ITS and LSU sequences with 21 genera of Hypocreales including 14 genera in the Nectriaceae and 7 genera in the Bionectriaceae. Varicosporellopsis is primarily characterized by obpyriform, pale orange, non-stromatic ascomata not changing colour in 3% KOH, becoming very pale yellow to nearly hyaline in lactic acid, short-ribbed ascospores, freshwater habitat and an acremonium-like asexual morph
