Illustration of TLC data for species of Niebla

     Niebla spatulata is a species of fruticose lichen found mostly in Baja California Sur.  It is also  recognized here as a species complex occurring at three major locations: (1-type) Sierra Hornitos on the Vizcaíno Peninsula, (2) Isla Cedros, and (3) near El Tomatal, while there are other minor locations in between.  The third location, just north of state line of Baja California, was near a border checkpoint, where over the years the population may have been extirpated.  It could not be seen when in 2016.

     The species complex is characterized by a thallus divided into small tufts of flattened branches, dilated, lacerated and fringed near apex, and by having hypoprotocetraric acid with or without  4-O-demethylnotatic acid and/or salazinic acid (N. flabellata Spjut 1996), rarely with no detectable lichen substances (acid deficient, N. aff. homaleoides).  Niebla spatulata was recognized by Spjut (1996) to occur with  N. flabellata and easily distinguished by lichen substances; however, this distinction has yet to find support in DNA phylogeny, or by analytical species discrimination methods (Spjut et al., 2020). Nevertheless, their close association sharing the same chemotypes over a broad geographical range within a well-defined ecoregion as a monophyletic group warrants recognition as a species complex that may be recognized by a greater density and slightly larger, more sharply defined pycnidia.

     Three cryptic species are evident in the phylogeny based on both salazinic acid and hypoprotocetraric acid thalli while only one was found by application of BPP and Stacey species discrimination methods based on the N. spatulata described to have  hypoprotocetraric acid  (Spjut et al. 2020, Suppl. 5).
