Type locality coordinates: 41°55'32"N, 8°44'11"E; 41.925556°, 8.736389°.

ITS barcode: Data lacking.

Description: Lichen. Thallus crustose, composed of rather discrete verrucae, rarely continuous. Apothecia lecideine, 0.2-0.5(0.7) mm diam., sessile. Hymenium inspersed with few to numerous oil droplets, 50-70 µm high. Hypothecium brown, with numerous oil droplets. Asci of Bacidia-type. Ascospores (10-)11-15(-18) x (4.5-)5-6(-6.5) µm, (M=13; 5.3 µm; s.d.=1.9; 0.5 µm; n=63), Dirinaria-type, smooth; torus not developed; ascospore-ontogeny of type B. Spermatia 6-7 x 1 µm, bacilliform (Giralt 2000: 312).

Photobiont: Data lacking.

Chemistry: Thallus K+ yellow. Diploicin (major), atranorin (minor), isofulgidin (minor), fulgidin (trace) and one additional unknown substance (submajor), by TLD and HPLC. The unknown substance is characterized by Rf classes 5/5/5-6 and absence of colour after visualization. Isofulgidin and fulgidin were not detected in specimens analysed only by TLC, for example in the type material of Buellia ericina. Only atranorin has previously been reported by Kalb & Hafellner (1992) and by Giralt & Matzer (1994). Diploicin, isofulgidin and fulgidin are reported here for the first time from this species and fulgidin and isofulgidin from the genus Rinodina (Giralt 2000: 312).

Ecology: On bark.

Distribution type: Macaronesian, West Mediterranean.

Taxonomy: The species has been described as Rinodina madeirensis from Madeira in 1992, as R. ericina was at that time considered to belong to the genus Buellia.
