'''''Ionaspis''''' is a genus of lichen-forming fungi in the family Hymeneliaceae.<ref name="Wijayawardene et al. 2022"/> It contains six species of saxicolous (rock-dwelling), crustose lichens. The genus was originally circumscribed in 1871 by Theodor Magnus Fries. He segregated the genus from ''Aspicilia'' based on the presence of ''Trentepohlia'' rather than ''Trebouxia'' as the {{lichengloss|photobiont}} partner.<ref name="Fries 1871"/>
