'''''Myriochapsa''''' is a [[genus]] of [[corticolous lichen|corticolous]] (bark-dwelling), [[crustose lichen]]s in the subfamily Graphidoidae of the family [[Graphidaceae]]. It has three species.<ref name="Wijayawardene et al. 2022"/> The genus was [[circumscription (taxonomy)|circumscribed]] in 2013 by Marcela Cáceres, [[Robert Lücking]], and [[Helge Thorsten Lumbsch|H. Thorsten Lumbsch]], with the Brazilian ''[[Myriochapsa psoromica]]'' assigned as the [[type species]]. The generic name combines ''[[Myriotrema]]'' and ''[[Chapsa]]'', referring to the two Graphidaceae genera that it resembles. The main distinguishing characteristics of the new genus are its densely corticate [[thallus]], and the presence of the [[lichen product]] [[psoromic acid]]. Additionally, its [[apothecium|apothecia]] have wider pores, with differently textured margins.<ref name="Parnmen et al. 2013"/> Although originally created as a [[monotypic]] genus, [[Harrie Sipman]] added two South American species in 2014.<ref name="Sipman 2014"/>
