Catillaria arthonioides A. Massal., Geneac. lich. (Verona): 19 (1854).

Notes: Melaspilea was introduced for two species M. deformis and M. arthonioides. Taxa in this genus are distributed worldwide and occur primarily as epiphytes on bark or wood, rocks and parasites or commensals with lichens (Ertz and Diederich 2015). Melaspilea is a heterogeneous group and more collections are needed to resolve the genus (Ertz and Diederich 2015).
