Ramalina europaea Gasparyan, Sipman & Lücking

Lichenologist, 49: 306, 2017.

Synonyms:

Distribution: N - Frl (TSB).

Description: Thallus fruticose, pale yellowish green to green, erect to subpendulous, of discrete lobes often coalescing to form extensive swards, up to 1(-3) cm long, several times palmately or dichotomously branched from a narrow or expanded holdfast. Lobes usually flattened, up to 3 mm wide, solid, usually developing numerous tiny, irregular, somehow spine-like lateral lobules bearing a terminal, punctiform soralium, the lower side often with ovoid excavate depressions (especially evident in epiphytic samples). Soralia in mature thalli often terminal on widened, somewhat vaulted lobes, but never becoming large and labriform. Soredia granular, 50-70 µm wide, easily abraded and leaving a whitish surface on the soralia. Cortex thin, with chondroid strands; medulla white, compact. Apothecia very rare, lecanorine, 1-3 mm wide. Asci 8-spored, clavate, Bacidia-type. Ascospores 1-septate, hyaline, broadly ellipsoid, 10-15 x 4-5 µm, straight or slightly curved. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: cortex with usnic acid; medulla with evernic acid.

Note: a recently-described species, apparently widespread in Central Europe, found both on rocks and tree bark. The Italian material of R. pollinaria should be checked against this species, which is characterized by the punctiform soralia borne terminally on tiny spine-like, lateral branches, and by the farinose soredia.

Growth form: Fruticose

Substrata: bark and rocks

Photobiont: green algae other than Trentepohlia

Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
