Crustose Lichens for ID Help Please.

[Lancashire Lad]

Found these yesterday, all growing on dry stone walls (limestone) in the Malham / Goredale area.

No.1...........................No.2............... ...........No.3...........................No.4


My (very) tentative ID suggestions: -

No's 1 to 3 possibly Caloplaca flavescens?
No.4 possibly Aspicilia calcarea?

Any help with ID confirmation/other appreciated.

Regards
Mike.

For what it's worth, I agree.

(not sure when I'll deal with them, but I now have a few more Caloplaca species to go up on my site.)

Thanks Alan - (Let the celebrations begin - For once I've actually managed to ID correctly ).

I appreciate that these two are fairly commonplace and should be easy to ID, but there seems to be so much variation within different examples of the same species. (Especially when trying to compare a find against various on-line & textbook photo's). - So much so that I am generally hesitant to profer my tentative suggestions.

Regards
Mike.
