Niebla usneoides : ウィキペディア英語版 | Niebla usneoides
''Niebla usneoides'' is a fruticose lichen that grows on rocks in the fog zone along the Pacific Coast of Baja California in the Vizcaíno Desert and Magadalena Desert regions, and reported also from the Channel Islands and mainland of southern California.〔Spjut, R. W. 1996. ''Niebla'' and ''Vermilacinia'' (Ramalinaceae) from California and Baja California. Sida Bot. Misc. 14〕 The epithet, '' usneoides'' is in reference to the similarity to the lichen genus ''Usnea''. ==Distinguishing Features==
''Niebla usneoides'' is distinguished by a thallus divided into numerous subtubular more or less linear shaped branches, to 4 cm high and 8 cm across, that are fringed above with spiculiform branchlets and by short coralloid isidia (isidium) along margins. The branches become terminally whip-like, or abruptly curved.〔 Pycnidia and apothecia are absent.〔 Similar species are ''Niebla suffnessii'' and ''Niebla isidiaescens''. ''Niebla suffnessii'' is viewed as the fertile counterpart of a species pair (''N. suffnessii'' and ''N. usneoides'').〔 They appear to intergrade by isidia in rare thalli occurring sparsely at the base of the thallus of ''N. suffnessii''.〔 ''Niebla isidiaescens'' differs in having divaricatic acid instead of sekikiaic acid and by the presence of pycnidia.〔
