Isla Guadalupe, Palmer s.n.,
collected in 1875, holotype (US)


     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). The species resembles N. caespitosa in the dilated thallus branches that have ragged margins and a reticulate ridged cortex, but differs in producing isidia.
