Bacidia iberica, a new epiphytic species, is described from central and southern Spain. It is closely related to Bacidia rubella (Hoffm.) A. Massal. The most important differences are in thallus morphology. Bacidia iberica has a squamulose thallus and whitish to greenish gray ascending squamules, whereas B. rubella has a granular thallus. In addition, B. iberica has slightly paler apothecia than B. rubella. Spore length, width, and length/width ratio are significantly different for the two species.
