Niebla rugosa
''Niebla rugosa'' is a fruticose lichen that grows on rocks along the foggy Pacific Coast of Baja California in the Vizcaíno Desert.〔Spjut, R. W. 1996. ''Niebla'' and ''Vermilacinia'' (Ramalinaceae) from California and Baja California. Sida Bot. Misc. 14〕 The epithet, ''rugosa'' is in reference to the wrinkled reticulated surface of the thallus.
==Distinguishing Features==
''Niebla rugosa'' is distinguished by a thallus divided into relatively few—less than 20–branches from a yellow pigmented holdfast, the branches generally strap-shaped, oblong to linear in outline,〔Oblong & linear: branches with parallel margins. Oblong: branch length less than 10 times width. Linear: branch length 10 or more times width〕 to 4 cm long and 3–7 mm wide, mostly simple, wavy along acute margins and cortical ridges, occasionally with short rounded lobes, especially near apex, with longitudinal spiraling ridges that divide and unite generally at 45° to form angled margins and intermittent ridges, the longitudinal ridges connected by transverse ridges, similar to a spiraled ladder (or DNA helix), and by containing divaricatic acid, with triterepenes.〔 Similar species are ''Niebla siphonoloba'', distinguished by the lichen substance sekikaic acid and by transverse ridges branching between margins, ''Niebla podetiaforma'', distinguished by reticulated vein-like cortical ridges between margins, ''Niebla contorta'' distinguished by the obtuse branch margins, and ''Niebla undulata'' that differs by having a smooth recessed cortical surface between ridges.〔
