Niebla marinii is a fruticose lichen that grows on lava along the Pacific Coast of Baja California from near San Fernando Canyon south to Morro Santo Domingo.

[7] 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.

Sinuous cortical ridges are generally characteristic of the sekikaic-acid species Niebla siphonoloba throughout its geographical range,[7] and it occurs frequently on Mesa Camacho.

[1] This species (N. siphonoloba) is recognized by its simple stubby branches in addition to having sekikaic acid and a prominent reticulated (honeycomb-like) cortex.

A logical explanation for the occurrence of the distinct cortical sinuous ridges in N. marinii and N. suffnessii on Mesa Camacho is hybridization,[10] which in lichens is rarely mentioned, and when it is, it usually is in context with chemical variation.
