I found this placodioid brown crust on a boulder in a grassy field and collected a portion with permit for UCD. It has numerous tiny spores per ascus, the hymenium height is roughly 100-130 microns, and the thallus is K negative, P negative and C plus pink (faint transient flush of pink under compound scope).

Growing on shrub twigs in a narrow sandy wash, collected a portion with permit for UCD. Most of the twigs were covered in Candelaria concolor, this crust with 0.5 mm black apothecia and circa 16 x 6 micron gray-brown spores with one septa was a minor component of the specimen.

I found this somewhat warty pale crust growing on the north face of a slick black, HCL-negative rock (basalt?) in a riparian area. The thallus has 1-1.5 mm areoles that appear to be pruinose and sunken blackish apothecia. There seem to be two populations of ascomata - one with globose hyaline 20-micron spores and one with sickle-shaped one-septate spores measuring about 24 x 7 microns, both 4-8/ascus. The epihymenium is blue-green for some of the apos. I collected a portion with permit for UCD.
This observation is for the parasitic fungus growing on the Aspicilia/Circinaria lichen - thanks to Valerii Darmostuk from the Lichenicolous Fungi 2.0 Facebook site for the genus ID. The host lichen is posted here:

Lumpy crust growing on south-facing rock outcrop in arid sandy wash, collected a portion with permit for UCD. Thallus and apothecia are K negative; many apothecia with white pruina. Asci with mostly 4-6 spores per ascus, spores are hyaline, globose and range from 21-26 microns in diameter when spherical-appearing and 29 x 21 microns when subglobose. Keys tentatively to Aspicilia "desertorum" in Sonoran Desert Flora, which is now this species...
