Identification: Unsure about sp.

I believe this lichen to be Caloplaca saxicola ssp. saxicola (Hoffm.) Nordin. It could even be Caloplaca citrina (Hoffm.) Would appreciate help from a member.

 

Richard Droker at http://www.flickr.com/people/29750062@N06/ is a lichen guy. He has a large collection of lichen photos and lots of knowledge about them, I believe.

 

Thanks Andrey, I will check the site of Richard Drecker.
