 "Niebla marinii" has been included under a very broad species concept, ("Niebla josecuervoi"); one that essentially recognizes only three species in the genus "Niebla", defined by a two-layered cortex, isolated chondroid strands in the medulla and by the lichen substances lacking the terpenes found in "Vermilacinia".Under the broad species concept, the morphological differences are seen as environmentally induced variation, and the chemical differences (e.g., "Niebla pulchribarbara", protocetraric acid) are viewed as belonging to a chemo-syndrome; however, no data was presented to support this view, other than reference to studies in other genera in which the species differences mentioned were not applicable.World Botanical Associates, "Niebla marinii", retrieved 28 Dec 2014, http
