Struggling with this

The material I have is not sorediate. Doesn’t even look like it came from the same thalli that are in the photo. What I have in front of me is badly discolored by unlichenized green algae.

I’m struggling to tell what the difference is between Lecanora hybocarpa and Vainionora americana. There might be some chemistry (TLC required). The conidia are bacilliform in Vainionora compared to filiform in Lecanora s. str.. But I can’t find a description of V. americana, so I can’t tell what else. I know I’ve made the mistake before of not noticing soredia and mistakenly calling V. americana L. hybocarpa. (James Lendemer caught my mistake last time.)

For now, let’s just go with soredia means V. americana. I think soredia are rare in L. hybocarpa (if indeed it has ever been reported at all).

This thing is sorediate?!

I’ll look at the specimen again…
