Synonyms: Fistulariella roesleri (Schaer.) Bowler & Rundel; Ramalina pollinariella (Nyl.) Nyl.
Description: Thallus fruticose, pale green, 1-6 cm long, loosely tufted, richly branched, erect to subpendulous, the primary branches flattened, 1-2.5 mm broad, the secondary branches mostly arranged at right angles to the main axis, often of variable thickness along their length, ending in many fine, terete, often apically hooked branchlets. Surface smooth, glossy, sparingly to abundantly fenestrate. Medulla subfistulose, arachnoid to hollow in the inflated parts. Soralia punctiform, terminal or subterminal, consisting of a few granular soredia. Apothecia very rare, lecanorine, terminal or subterminal, with an often pruinose disc. Epithecium pale olive; hymenium and hypothecium colourless; paraphyses thick-walled, richly branched in upper part. Asci 8-spored, the apical dome K/I+ dark blue with a pale, conical-pointed apical cushion (axial mass), the wall I-, but the thin outer gel I+ blue, Bacidia-type.. Ascospores 1-septate, hyaline, straight, 11-16 x 5-6.5 µm. Photobiont chlorococcoid. Spot tests: K-, C-, KC- or KC+ pale yellow (cortex only), P-. UV-. Chemistry: cortex with usnic acid; medulla with substances of the sekikaic acid complex.
Growth form: Fruticose
Substrata: bark
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
