Pseudomurilentithecium was introduced by Hyde et al. (2020) based on the combined LSU and ITS phylogeny. The genus clusters within Lentitheciaceae. Pseudomurilentithecium shows close phylogenetic affinities to Poaceascoma and Setoseptoria (Hyde et al. 2020). However, Pseudomurilentithecium can be distinguished from Setoseptoria in having brown, fusiform and muriform ascospores whereas Poaceascoma has hyaline, filiform ascospores without vertical septa (Phookamsak et al. 2015). In this study, we introduce another species to the genus from Clematis vitalba.

 

Type species: Pseudomurilentithecium camporesii Mapook & K.D. Hyde, in Hyde et al., Fungal Diversity 100: 69 (2020).

Other accepted species: Species Fungorum – search Pseudomurilentithecium.
