In continuing the survey of the Nectriaceae in temperate areas (Lechat & Aplin, 2016; Lechat & Fournier, 2015, 2016, 2017, 2020; Lechat & Priou, 2008; Lechat & Rossman, 2017; Lechat et al., 2010, 2014, 2015, 2018a, 2018b, 2019, 2021) a cosmospora-like species was repeatedly collected on dead stems of Ruscus aculeatus […]
