Dear Debbie and Jason,
Thanks for your praise. The yellow endolithic crustose lichen next to Thyrea seems to me to be Caloplaca ochracea. A common species here around (limestone all over the place). The same as at
But, this is not at all sure. Usually its thalus is light and pale but distinctly yellow. In this pictures something gray seems to be overgrowing it. Endolithic crustose lichens are mostly still a mystery for my level of knowledge.
I would love to see one of these. Great photos! (And even better notes, wish everyone — myself included — took as much care posting observations…)
(What’s the beautiful orange endolithic crustose species behind it? Candelariella?)
