Nice 2-cm round rosettes on a rock in a dry wash, collected a portion with permit for UCD. Keys to Acarospora rosulata, as best I can tell - perhaps a more classic appearance (rosette-like?) than my previous specimen?

Description

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).

@mossgeek, @j-dar, I don’t think I’ve seen this one before. I did not feel safe to climb any closer, but looked new to me.

Description

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:

@mossgeek, @j-dar :
Amazing lichens and mosses in the upper Alder Creek canyon accessible by the gated road coming down the valley from Charleton Flat picnic area.

After a rain, they all looked plumped up and vivid, so I’m struggling with IDs.
