When: 2017-03-03
Collection location: Bear Gulch, Pinnacles National Park, San Benito Co., California, USA [Click for map]
Who: Pgrunow
Notes:
Caloplaca Lichens
I can safely eliminate:
Albovariegata- bluish gray thallus, black apothecia
Atroflava- dark gray/brown thallus
Bolacina- yellow apothecia rims, thallus scattered, yellow squamules without the elongate marginal lobes this specimen has
Cerina- gray-rimmed, on trees
Citrina- like candelariella
Chrysophthalma- no elongated lobes, very disorganized
Coralloides- clustered, like xanthoria candelaria
Demissa- olive/gray/brown thallus, on cliffs
Epithallina- parasitic
Ferruginea- on trees
Flavorubescens- on trees, no lobes
Ludificans- thallus with little structure, grayish or yellowish and without the marginal lobes,
Luteominia- apothecia deep red, also without elongated colored margin
Nashii- no elongated lobes
Oregona- on trees
Persimilis- no lobes, on wood
Pyracea/ holocarpa sensu CA- on trees, looks like crenulata
Squamosa- as subsoluta, below
Stanfordensis- on trees
Stantonii- bicolored, margin without long distinct lobes
Subsoluta- thallus crowded and somewhat disorganized in shape, lacks elongated love tips
Variabilis- blackish apothecia, quite different
Can probably eliminate:
Decipiens- pruinose yellow\gold, apothecia very sparse, yellow soralia
Ignea- very red orange, apothecia concentrated at center
Stellata- apothecia sparse, star shaped lobes
Trachyphylla- surface rough\verruculose
Realistically, this leaves C. Saxicola and C. Impolita, assuming this is not X. Elegans

I have looked at that checklist. I included all the caloplaca spp on there, as well as other potential ones that are not extremely rare. I have found a couple of lichen species not listed on the checklist at Pinnacles, such as peltigera membranacea.
A good list is here:
http://lichenportal.org/...
18 species of Caloplaca!
Sorry, I didn’t mean to push you for all that detail, just trying to be helpful with the link. C. saxicola has apothecia that originate near the lobe tips, which these seem to do, so totally possible.
