Scytinium lichenoides (L.) Otálora, P.M. Jørg. & Wedin

Scytinium lichenoides is a dark grey to brown-black foliose cyanolichen. Until recently, it had usually not been distinguished from S. pulvinatum, from which it differs in coralloid marginal isidia and partially also in its ecology. While S. pulvinatum mostly grows on saxicolous and terricolous bryophytes, S. lichenoides is often epiphytic, usually on moss-covered roots and bases of deciduous trees. A majority the of S. lichenoides records in the Czech Republic probably refers to the more common S. pulvinatum. The occurrence of S. lichenoides s. str. in currently little known. Two records from the beginning of the 20th century (Vápenný Podol, leg. V. Kuťák; Hradisko near Znojmo, leg. A. Oborny) were confirmed in the Swedish Museum of Natural History Herbarium in Stockholm [] during the revision by Otárola et al. (2008). Recently, it was found on saxicolous bryophytes in the Oslava river valley, as an epiphyte on moss-covered roots in scree forests in the Křivoklát region (Týřov) and on calcareous flysch in the Beskydy Mts (Velký Polom).
