MycoBank number: MB 2746; Index Fungorum number: IF 2746; Facesoffungi numbers: FoF 06389; – 2 morphological species (Species Fungorum 2020), 2 species with molecular data.
Type species: Lepidopterella palustris Shearer & J.L. Crane, Trans. Br. mycol. Soc. 75(2): 194 (1980).
Notes: Lepidopterella was introduced by Shearer and Crane (1980) and placed in Argynnaceae. The asexual morph has not been reported. Species are saprobic fungi in aquatic habitats (Raja and Shearer 2008; Shearer et al. 2009; Hyde et al. 2013). Sequence data are available for the type species, Lepidopterella palustris, and L. tangerina. Phylogenetic analysis indicated that the type species represents a basal taxon to Mytilinidiales in Dothideomycetes with moderate support (Shearer et al. 2009). Lepidopterella shares butterfly-shaped ascospores with Argynna, but differs in having globose to subglobose ascomata, and papilionaceous to broadly reniform, brown to orange-brown ascospores (Hyde et al. 2013).
