Presence of apothecia is a coin toss. It’s a profoundly ugly thing in most cases. :) But its ubiquitousness (iniquitous ubiquity?) and breathtaking variability make it something you’ve gotta respect despite everything else. At least it’s got the C test. It’s something.

C+ pink, but didn’t find any apothecia

This is one of those things most people probably never notice (unless they’re looking for lichen :)

This looks just like Trapeliopsis granulosa. Sometimes if you put it under a hand lens you can see tons of tiny pinkish-to grayish little apothecia scattered among the soredia. Very common and widespread species on dry, exposed soil. Verify with C test (C+ and KC+ pink).

I wish I had the equipment to show this lishen in all the detail, but I don’t. It consists of tiny cushions of thallus, with soredia scattered all over it. The greenish regions you see in the photos are thallus, and the yellowish are soredia.
