ABSTRACT: Gymnoderma, which has been considered a monotypic genus, is composed of three insulare is described from Japan and differs from G. coccocarpum of southeastern smaller and having a thicker cortex with didymic acid present. G. lineare from the Southern Appalachians is transferred from Cladonia because the podetia lack symbiotic algae, are solid, and are located on the marginal lower side of the thallus. Gymnoderma, including three species and possibly representing an ancestral form of Cladonia, is disjunctively distributed in eastern Asia and the Southern Appalachians. G. coccocarpum is reported from Thailand and Borneo for the first time.
