Niebla lobulata is a fruticose lichen that grows on rocks in the fog regions along the Pacific Coast of Baja California, from Bahía de San Quintín to Vizcaíno Peninsula and offshore islands, Isla San Martín,[1] and Guadalupe Island.[2] The epithet, lobulata is in reference to the lobed margins of the thallus branches.
Niebla lobulata is distinguished by a thallus divided into mostly strap-shaped branches from a basal holdfast, the branches not more than 20 in number, wide spreading above a short tapered and narrow base, occasionally dividing into similar branches, the branch margins often wavy (undulate), and/or lobed, or lacerated, the whole thallus not more than 7 cm high.[2] The species (N. lobulata) also recognized by containing sekikaic acid (with triterpenes), and by a relatively thin cortex, (0-)35–75(-100) μm thick, eroding near base, covering a fistulose medulla (solid on Guadalupe Island), which seems related to the contorted appearance of the branches.[2] The species (N. lobulata) is most similar to Niebla undulata, which differs by having the lichen substance of divaricatic acid, instead of sekikaic acid.
