Thallus: fruticose, shrubby to subpendulous, up to 7(15) cm long; branching: irregularly or dichotomously branched from a narrow holdfast; branches: solid, flattened, minutely hairy, up to 3(-5) mm wide; surface: greenish gray to greenish yellow, irregularly uneven, dull, without soredia; pseudocyphellae: rare, ellipsoid, laminal or rarely marginal, flat to +depressed; cortex: thin; chondroid strands: continuous, smooth; Apothecia: common, submarginal, up to 3(-7) mm in diam.; disc: concave, with white pruina, without white margin; margin: concolorous with the thallus, reticulately rugose, with sparse pseudocyphellae; asci: elongate-clavate, 8-spored; ascospores: hyaline, 1-septate, broadly fusiform, slightly curved, 1316(- 19) x 4.5-5.6 µm; Pycnidia: not observed; Spot tests: cortex K-, C-, KC+ yellow, P-; medulla K-, C-, KC-, P-; Secondary metabolites: cortex with usnic acid (major); medulla: none detected.; Substrate and ecology: on bark; World and Sonoran distribution: infrquent in coastal, southern California.; Note: Ramalina puberulenta resembles R. leptocarpha, from which it can be distinguished by the presence of cortical hairs on the branch surfaces.
The surface of this lichen is covered with a velvet-like fuzz (use a hand lens to see this).
