Based on molecular phylogenetic analyses and ecological and morphological characteristics, Walsh et al. (2014) introduced Acidomelania as a monotypic genus for Helotiales, a heterogeneous and the largest order in Leotiomycetes, which includes endophytes, plant pathogens, and saprobes. The type species of this genus is Acidomelania panicicola, which was isolated as an endophytic species from the roots of Panicoideae (Walsh et al. 2014). Acidomelania sporulated at room temperature within three weeks with simple or occasionally branched conidiophores with hyaline conidiogenous cells, straight; cylindrical collarettes; conidia aggregated in slimy heads, globose to subellipsoidal, aseptate, hyaline, smooth-walled, whereas chlamydospores were present on WA with catenulate, intercalary, dark brown, subglobose (Walsh et al. 2014). Based on a study by Tanney and Seifert (2020), Acidomelania was synonymized with Mollisia based on morphological characteristics and reference DNA sequences.
