Ramalina capitata var. protecta (H. Magn.) Nimis

The Lichens of Italy: 597, 1993. Basionym: Ramalina protecta H. Magn. - Bot. Not., 109: 150, 1956.

Synonyms: Ramalina polymorpha var. protecta (H. Magn.) Clauzade & Cl. Roux

Distribution: C - Sar (Lo Forti & al. 2004).

Description: Thallus fruticose, greenish to greenish grey, 1-2(-3) cm tall, erect to ascending, rigid, abundantly branched, firmly attached by a basal holdfast, several thalli often forming dense carpets on the rock. Branches more or less flattened, 1-3 mm wide, longitudinally striate, with terminal, hood-shaped to labriform soralia; soredia granulose, concolorous to thallus. Subcortex cartilaginous; medulla white, compact. Apothecia extremely rare, lecanorine, mostly terminal. Asci 8-spored, clavate, Bacidia-type. Ascospores 1-septate, hyaline, often poorly developed. Photobiont: chlorococcoid. Spot tests: thallus K-, C-, KC-, P-; medulla and soralia K- or (rarely) K+ yellow turning red. Chemistry: cortex with usnic acid; medulla without lichen substances, or rarely with norstictic acid.

Note: often found together with the other varieties, especially with var. digitellata, but perhaps more frequent under overhangs; not uncommon in parts of Sardinia.

Growth form: Fruticose

Substrata: rocks

Photobiont: green algae other than Trentepohlia
