Athelia is a genus of corticioid fungi. Some species are facultative parasites of plants and of lichens (Sulistyo et al. 2021). A species of Athelia also engaged in a symbiotic relationship with termites (Reticulitermes), in which the fungus forms sclerotia that mimic termite eggs and worker termites handling the sclerotia as if they were eggs (Matsuura et al. 2005). Wijayawardena et al. (2022) accepted 32 species in this genus.
