Thallus fruticose, rather soft, yellow-green to white-green, up to a height of 6.0 cm, branched in a palmate or irregular manner, arising from a common holdfast. Lobes bifacial and flatted. Soralia initially marginal then extending to laminal, predominantly in the upper regions of the thallus. Pseudocyphellae absent or very rare. Apothecia rare, lecanorine, orbicular in shape, ranging from concave to predominantly flat, lacking pruina.

Chemistry: Medulla spot testsK–, C–, KC–, P–, UV–; TLC: Fatty acids. ( Krog & Østhagen 1980)

Note: Discovered as an admixture in a sample of R. canariensis . It is a widespread species in the Mediterranean region and grows often together with R. canariensis . Like the latter, it is found in coastal areas with a Mediterranean climate all over the world (GBIF accessioned 14.06.2024), perhaps as a result of human transport? In the surrounding countries of Iran it is reported from Turkey ( John & Türk 2017).
