Niebla fimbriata
''Niebla fimbriata '' is a fruticose lichen that grows on volcanic rocks in the Channel Islands of California and along the foggy Pacific Coast of Baja California from near San Antonio del Mar south to Arroyo Sauces, which is located south of Punta Canoas.〔Spjut, R. W. 1996. ''Niebla'' and ''Vermilacinia'' (Ramalinaceae) from California and Baja California. Sida Bot. Misc. 14〕 The epithet, '' fimbriata'' is in reference to the fringed branches of the thallus.
==Distinguishing Features==
''Niebla fimbriata'' is recognized by the thallus divided into subterete branches from a central attachment point, reaching a height of 6 cm while spreading out as much as 10 cm across; the branches seem to bend backwards as they grow, producing a fringe of narrow branchlets along both margins of a primary branch, all pointing in the same direction—upwards, the whole branch with its branchlets resembling the lobster body on its back with the legs pointing up, but branchlets may also fall off, leaving the margins of the primary branch to appear with rudimentary crinkled branchlets. Black dot-like pycnidia are scattered and immersed along the margins and cortical ridges, or they may be conspicuous and abundant in some thalli. The cortex is rather thick in covering a partially hollow medulla (“subfistulose”), 100–150(-200) µm thick, olive green in color with smooth, reticulate or honeycomb-like areas. Apothecia are born on the narrow branchlets. Lichen substances are sekikaic acid, with triterpenes.〔
''Niebla fimbriata'' is relatively infrequent and widely scattered in its occurrence. At the type locality (mesa above San Antionio del Mar) it was found with two rare species of ''Niebla'', ''Niebla pulchribarbara'', ''Niebla versiforma'', in association with common species, ''Niebla juncosa'', ''Niebla josecuervoi'', ''Niebla arenaria'', and ''Niebla effusa'' on lava among a low mixed chaparral desert succulent transition scrub that included ''Agave shawii'', ''Dudleya ingens'', ''Ferocactus'' spp. ''Mammillaria dioica'', ''Frankenia palmeri'', ''Eriogonum fastigiatum'', and ''Rosa minutifolia''.〔 This area is just north of Punta Colonet, not between Ensenada and Tijuana where there has been active Real Estate development.
