Niebla palmeri is a fruticose lichen that infrequently occurs on sandy beaches or gravelly soil along the Pacific Coast from San Diego, California to mesas just north of Punta Baja, about 15 miles southeast of El Rosario, Baja California.

[1] The epithet, palmeri is in honor of an Edward Palmer who collected the species in the vicinity of San Diego and on Isla Coronado.

Niebla palmeri is distinguished by a hemispherical mat-like thallus, divided into numerous tangled irregular shaped subtubular branches, varying from nearly linear[2] throughout to a thallus with variously dilated and flattened segments, to 8 cm high and 16 cm across, and by containing sekikaic acid, with triterepenes.

[1] Only five specimens of N. palmeri were reported to have been collected, all at the United States National Herbarium (Smithsonian Institution, Museum of Natural History, Department of Botany),[3] which includes one of his collections obtained from a mesa above Punta Baja;[1] however, Phillip Rundel and Peter Bowler recognized a “sekikaic acid race” of Niebla homalea at Colina del Sudoeste, Bahía de San Quintín “limited to shrubs growing on sand dunes and to lava surfaces on lower slopes”.

[4] A specimen cited by Spjut[1] was collected on sand at Bahía de San Quintín by Velva E. Rudd (3340A) in late January 1972 in regard to the Edward Palmer Project.
