Thanks for the ID. :)

Can I get your opinion on a few other lichen observations?

http://mushroomobserver.org/208499 (EDIT: observation destroyed)

I’m confident in my ID of the former. The latter…really unsure. In my beginner brain, barnacle-like = Thelotrema.

Perfect!

Good, no question it is Ramboldia russula now. This thing turns the coolest striking vivid purple under microscope when you add KOH to the slide. And has neat “acicular” (needle-like) multiseptate spores. Never gets old. :)

Hey Jason, I returned today and took some dry close-ups. Hopefully these are better for ID.

Cool!

Most of that is beyond my skill level and budget right now, but I think I can manage some dry close-up photography. :)

Depends how much you want to learn about lichens! :)

This thing is probably really beautiful under a dissecting scope, and it will have dramatic reaction to KOH, and probably interesting spores to boot. A good introduction to the wonders of crustose lichens! :)

But if we just want a good id, then a good close-up photo of it while dry may well be enough to clear up any doubt.

I’ll do my best!

No rain today, and the forecast is promising.

Should I also collect a specimen or something? (I’m clueless.)

Both dry and closer will help

I have trouble identifying wet specimens from photo. :(

Hmm…

I plan to return to this site in the next day or two, and I can try to take closer/better photos at that time.

Still can’t tell!

Cover all the bases instead.

Briganteae leucoxantha always has scattered apothecia in my photos, and is brighter orange, even when wet.

Ramboldia russula is closer in color, but I don’t remember seeing clustered apothecia in it, either.

Caloplaca is not common on Florida, and most records are an isidiate thing (C. epiphora) which looks totally different. Can’t think of any plausible candidates… but that doesn’t rule it out conclusively.

I added a closer photo. Let me know what you think!
