Abstract: Two new species of Stylonectria are described and illustrated from specimens collected in the French Alps. Ascomatal morphology, fungicolous lifestyle, and phylogenetic comparison of their ITS sequences with species in six similar genera of Nectriaceae having a fusarium-like asexual morph support their placement in Stylonectria. Based on morphological divergences of both sexual and asexual morphs, as well as the ITS sequences from known Stylonectria species, S. alpina and S. tuedensis are proposed as new species.

An inventorial survey of Ascomycota in the French Alps, initiated by in Vanoise National Park in August 2020, led to the discovery of two new species of Stylonectria Höhn. (Hypocreales) occurring […]
