35.7628° -121.0206° 332m
Habitat: Buckwheat scrub in dry open grassland hillside with scattered Pinus sabiniana and Quercus ssp; growing only on the Pinus. The rare vascular plant, Eriastrum luteum, occurs here. Numerous other lichens present, yet to be identified…
Features: Bright yellow thallus, attached at one central point, lacking rhizines. Thallus with pale wrinkles, medulla yellow. Pycnidia common, blackto brownish. Lacking soredia and isidia, apothecia common, crenate, with brown shiny disk. Spot tests K-, C-, supposed to be KC+ yellow, but its already yellow, so hard to tell.

Yes, that green-black thing is definitely Kaernefeltia merrillii, right on cue. :) Can’t tell what the other things are, maybe Parmelina coleae and Alectoria imshaugii (or an Usnea sp.)? Hypogymnia imshaugii and Letharia spp. are some other species to look for there.
(Up north you could fairly expect to find Tuckermannopsis platyphylla, by the way.)
That’s the dark lichen in the photo. I went there in the keys yesterday but left quickly for some reason.
You’ll just have to make that trip down here to see the assemblage in person…
There is a very strong species assemblage in this sort of habitat up north in the east Cascades: V. canadensis, Kaernefeltia merrellii, Nodobryoria abbreviata, Usnea lapponica, U. hirta, Lecanora laxa, L. schizochromatica, Lecidea rubrocastanea, Buellia punctata, B. griseovirens to name a few. I found it on the east slope of the Ventana Wilderness near Monterey a couple months ago. Your locality has got to be one of the southernmost examples of it. The Ventana locality was missing Vulpicida canadensis, and U. substerilis replaced U. lapponica, but was otherwise spot on.
Neat that there is a rare plant in the area, too.
Do you recognize the dark lichen in photo 1d? I didn’t bring much material home, I keyed it to Tuckermannopsis, with distinctly raised pycnidia, but some parts didn’t seem to match. I’ll post an observation with the few photos I was able to get.
Dry pine-oak mixed in with chaparral and scrub in the interior region is pretty common, but this location gets more rain. I’ll have to look and see what the range of this species is locally.
