Niebla tesselata
''Niebla tesselata'' is a fruticose lichen that grows on rocks along the foggy Pacific Coast of in the Northern Vizcaíno Desert of Baja California.〔Spjut, R. W. 1996. ''Niebla'' and ''Vermilacinia'' (Ramalinaceae) from California and Baja California. Sida Bot. Misc. 14〕 The epithet, ''tesselata'', is in reference to the cobblestone pattern on the surface of the thallus branches.
==Distinguishing features==
''Niebla tesselata '' is distinguished by the thallus divided into tubular branches from a pale rusty orange pigmented holdfast, the branches generally narrowly conical, simple, densely covered by black dot-like pycnidia〔Pycnidium (pycnidia plural) is a small flash-shaped structure (200–350 µm long) that produces conidia, which escape through an opening (ostiole) at the top and function in reproduction, asexually or sexually, appearing dot-like from surface view〕〔Bungartz, F. 2002. Morphology and anatomy of conidia-producing structures, Lichen Flora of the Greater Sonoran Desert 1: 35–40〕 positioned centrally on areolae, and by containing sekikaic acid, with triterepenes.〔 The species (''N. tesselata'') is unique in the genus for its simple branches and for the central development of pycnidia on the raised areolate surface, as opposed to developing along the cortical ridges as generally recognized for the genus ''Niebla''. Also, pycnidia are not confined to the upper parts of the branches as in most species of the genus; instead, they extend to the base of the thallus. Apothecia (ascocarp) are unknown.〔
