Scolecoleotia was introduced as a coelomycetous genus incertae sedis in Leotiales (Leotiomycetes, Ascomycota) by Boonmee et al. (2021) to accommodate the type species Scolecoleotia eriocamporesi, based on evidence from morphology and phylogenetic analysis of combined ITS, LSU, SSU and rpb2 sequence data. Morphologically, the genus is characterized by immersed, uniloculate, black, pycnidial conidiomata; pycnidial walls composed of pseudoparenchymatous cells arranged in textura angularis to textura globulosa; hymenium composed of polygonal cells; phialidic, discrete, hyaline, ampulliform to subcylindrical conidiogenous cells; and acrogenous, scolecosporous, solitary, cylindrical to filiform, curved, hyaline, aseptate conidia (Boonmee et al. 2021). Scolecoleotia is most similar to Gelatinosporium in having phialidic conidiogenous cells and conidial features, but it differs from the latter by having distinct ascomata (Funk 1979). The various shapes of ascomata are present in Gelatinosporium, while the ascomata of Scolecoleotia are elongate subsphaerical conidiomata (Funk 1979; Boonmee et al. 2021). Scolecoleotia is monotypic, containing the single species S. eriocamporesi, which was reported as saprobe isolated from dead aerial fronds of Pteridium aquilinum (an eagle fern) in Italy (Boonmee et al. 2021). Fresh collections are needed to provide insight into its ecology with host relationships.
