Roccellinastrum is a genus of lichen-forming fungi in the family Ectolechiaceae. It has seven species.
The genus was circumscribed in 1968 by the German lichenologist Gerhard Follman, with Roccellinastrum spongoideum assigned as the type species. This byssoid lichen (appearing wispy, like teased wool) was found growing on cactus spines in the fog oases of western Chile. Follman classified the genus in the family Chrysothricaceae, as he emphasized the taxonomic importance of the byssoid thallus, and the similarity of the apothecium and ascus structure to those in that family.[1] In 1983, Aino Henssen and colleagues emended the genus and placed it in the family Lecideaceae.[2]
