Type species – Acaulium albonigrescens Sopp

Notes – The asexual morph is hyphomycetous and has been treated as a synonym of Scopulariopsis by Seifert et al. (2011). Species occur in terrestrial habitats worldwide and are characterized by annellidic conidiogenesis with mycelium forming hyphal fascicles and guttulate conidia. Taxonomic revisions were carried out by Kirk et al. (2013). Sandoval-Denis et al. (2016a) accepted, Acaulium, in Microascaceae by segregating it from Microascus and Scopulariopsis based on molecular phylogenetic study. The placement of the genus was also accepted in Maharachchikumbura et al. (2015, 2016b) and Wijayawardene et al. (2017a, 2018a).
