Abstract: Lasionectriopsis germanica gen. and sp. nov. is described and illustrated based on a collection from Germany. The asexual morph of this fungus was obtained in culture and the culture was sequenced. The genus is placed in the Bionectriaceae based on ascomata not changing colour in 3% KOH or lactic acid, and phylogenetic comparison of LSU sequences with species in 14 genera of the Bionectriaceae. Lasionectriopsis is primarily characterized by whitish to pale orange, globose ascomata, semi-immersed in a subiculum, and verruculose ascospores. Based on molecular data, two species known only as asexual morphs, Acremonium pteridii and A. spinosum, are recombined in Lasionectriopsis.

In the continuation of the survey of hypocrealean fungi, an intriguing fungus was collected on decorticated, dead wood of Fagus sylvatica L. (Fagaceae), which did not match any known genus […]
