Xanthoparmelia cf ahtii (Essl.) O. Blanco, A. Crespo, Elix, D. Hawksw. & Lumbsch
Ahtii's Neofuscelia Lichen

This foliose lichen grows on acidic rock and is a distinctive olive green. It is reproductive with brown apothecia on very short stalks.
Xanthoparmelia ahtii belongs to a group of lichens that can only be differentiated by thin layer chromatography (TLC), to which we do not have easy access. Other lichens in this group include X. brunella, & X. infrapallida. X. ahtii has "unidentified fatty acid TE-8" as a major constituent, whereas X. infrapallida has "unidentified fatty acid TE-13" as a major constituent. X. brunella has "unidentified fatty acids TE-10 & TE-11" as major constituents. Since we have not done TLC, we cannot say for sure which of these lichens ours really is. Our lichen is spot test K-, so it is not X. atticoides. The morphological differences between the other three possibilities are unreliable apparently, but ours seems to most resemble X. ahtii.
We found X. cf ahtii growing on granitic rock along Bear Creek in Ponderosa forest 1 mi north of Pinos Altos at about 7,000 feet elevation.
