Résumé (anglais) : Clonostachys moreaui sp. nov. is described and illustrated based on a collection on dead corticated branches of Laurus novocanariensis in Madeira (Portugal). This species is placed in Clonostachys based on its clonostachys-like asexual morph, ascomata not changing colour in 3% KOH or lactic acid and phylogenetic comparison of its LSU sequence with those of 17 known species of Clonostachys. Clonostachys moreaui is primarily characterized by smooth to slightly roughened, orange, globose, bionectria-like ascomata with wall cells containing numerous orange oily droplets, crowded on an erumpent pseudoparenchymatous stroma and faintly warted ascospores (14–)15–18(–20) × 6–7 µm. Based on the comparison of morphological characteristics of sexual-asexual morphs and molecular data with known species, C. moreaui is proposed as a new species

During a foray in Levada dos Cedros, Madeira (Portugal) in July 2019, an hypocrealean fungus morphologically similar to Clonostachys rosea (Link) Schroers, Samuels, Seifert & W. Gams (Schroers, 2001) was collected on dead corticated branches of Laurus novocanariensis […]
