 Evidence for hybridization is seen by the same morphological variation in another species; one that has the bushy habit and smooth cortex of "N. marinii", "Niebla suffnessii" as found at its type locality—Cerro Elefante on the Vizcaíno Peninsula.Approximately 200 miles north of Cerro Elefante—which is about halfway up the northern Baja peninsula and just north of Punta Canoas—are both "N. marinii" and "N. suffnessii" that occur together on Mesa Camacho—a red lava mesa, 300–400 m in elevation.At this location, the thalli of both species have conspicuously raised sinuous (short wavy) cortical ridges; proposed species names have been suggested, one for the salazinic acid species, the other for the sekikaic acid species.
