Niebla halei
''Niebla halei'' is a fruticose lichen that grows on rocks along the foggy Pacific Coast of northern California on San Bruno Mountain〔Spjut, R. W. 1996. ''Niebla'' and ''Vermilacinia'' (Ramalinaceae) from California and Baja California. Sida Bot. Misc. 14〕 The epithet, ''halei'' is in honor of Mason Hale who encouraged taxonomic revision of the genus ''Niebla''.〔
==Distinguishing Features==
''Niebla halei'' is characterized by a tiny hemispherical thallus, 1.5 cm high and 2.5 cm across, with numerous very narrow branches, 0.3–1.0 mm wide, arising from a common attachment area on rock, and by dividing several or more times, more so near apex where shortly bifurcate (bifurcation) or antler-like. Black dot-like pycnidia that generally characterize the genus are inconspicuous at apex of branches. The key lichen substance is divaricatic acid (with triterpenes).〔
The increased branching of the thallus towards apex is similar to that of ''Niebla dactylifera'', known only from San Nicolas Island; it differs in having the lichen substance, sekikaic acid. The cortical ridging and branching of ''N. halei'' are also similar to specimens collected by Charis Bratt on Santa Cruz Island (Bratt 6431) and in the Santa Ynez Mountains on mainland California (Bratt 7202), referred to ''Niebla testudinaria''〔''Niebla testudinaria'', World Botanical Associates, retrieved 22 Dec 2014, http://www.worldbotanical.com/niebla_testudinaria.htm#testudinaria〕 by the larger size and less frequent occurrence of short bifurcate branches near apex.〔
