Clonostachys saulensis sp. nov. is described and illustrated based on a collection on bark of dead liana in French Guiana. This species is placed in Clonostachys (= Bionectria) based on its clonostachys-like asexual morph, ascomata not changing colour in 3% KOH or lactic acid and phylogenetic comparison of ITS sequences with known species of Clonostachys. Clonostachys saulensis is primarily characterized by non-stromatic, smooth, pale brown, globose ascomata coated with a whitish powdery scurf from base up to half height and turning blackish upon drying. Based on comparison of morphological characteristics of sexual-asexual morphs and molecular data with known species, C. saulensis is proposed as a new species.
During an inventorial survey of fungi in Saül (French Guiana) in August 2018 (Lechat & Fournier, 2018; 2019), an intriguing hypocrealean fungus was collected on dead bark of the woody liana Bauhinia sp. (Fabaceae) […]
