Hi All,
I'm hoping someone can lead me to a genera for this crustose lichen I found in Tehama County, California. It's on moss and rock at 400 feet elevation. The medulla is K- C- KC+fleeting red P- I+B. Spores are muriform, dark and 23-28.16x12.8µ.
Pictures in the photo gallery labeled California lichen.
Thanks,
Steve
