Phylogenetic comparison with genera belonging to the Nectriaceae and having an acremonium- or fusarium-like asexual morph places the three new species in Dialonectria.

In continuing the survey of the Nectriaceae in temperate areas (Lechat & Aplin, 2016; Lechat & Fournier, 2015; 2016; 2017a; Lechat & Rossman, 2017b; Lechat et al., 2010; 2014; 2015; 2018), several specimens of cosmospora-like species were repeatedly collected on dead or effete stromata of Diatrypaceae […]
