     Niebla isidiosa is a lichen known only Isla Guadalupe. It was reported by Spjut (1996) to be known only from the type collected by Palmer in 1875; however, Elix and McCarthy have since found it on Isla Guadalupe (website, March 2005, with reference to J. A. Elix. & P. M. McCarthy, 1998: Catalogue of the lichens of the smaller Pacific Islands, Bibliotheca Lichenologica 70, 1 - 361). A more recent collection is noted above Baja peninsula.  The species resembles N. caespitosa in the broader and rigid thallus branches  with ragged margins and  reticulated ridged cortex, but differs in producing isidia.
