Rosette Lichen

Physcia sp.

Description:

Foliose, pale gray-green lichenized fungus with flat, black apothecia (with gray-green collars). Apothecia are disc-like structures which contain spores. Physcia species are within the family Physciaceae and are considered lichen-forming fungi. Lichens are composite organisms comprised of a fungus being inhabited by algae or cyanobacteria.

Habitat:

On a hardwood branch at the top of a ridge in a dense mixed hardwood/coniferous forest in Northwest Georgia (Gordon County), US

Notes:

I was unable to get a species level ID as I did not do a K-test (Potassium Hydroxide) or view spores with microscopy.

No species ID suggestions

Thank you! I thought it was a beautiful sight as well <3 I am asking Santa for a chemical reagent kit this year. I have needed one for quite some time now, and this would have been one of those!

Very pretty lichen - I really like the 5th photo of the entire thing, but the details in the close-up shots are amazing too <3.
