Synonyms:

Ramalina cuspidata Chem c p.p.

Ramalina atlantica W. L. Culb.

Ramalina curnowii var. atlantica (W.L; Culb.) D. Hawsk.



Family: RAMALINACEAE

Habitat: Xeric supralittoral  zone

Description

    Differs from the type by its negative chemical spot tests (Chem c) C-, K-, KC- (seldom KC+/- yellow), Pd-. UV-.  Thallus forming small tufts, composed of narrow branches, often black towards the base, sometimes at their tip, narrow and flattened, surface dotted with pale scars, notably towards the base. Terminal apothecia. Ascospores ellipsoid, 1-septate, 10-17 x 4.5-5 µm according to our measurements. Rare chemotype, on vertical walls or below sheltered and weakly acid rocks in the mesic zone, sometimes in the xeric zone, often with Hydropunctaria maura s.l. and Xanthoria aureola.

N.B. By its flattened branches with "scars" at the base, this taxon is easy to confuse with certain taxa of the Ramalina siliquosa group but it is differentiated from this group by its terminal apothecia, the ostioles of its black pycnidia and its chemical reactions negative.
