Location: 35°12’36.32"N, 85°55’53.79"W, el. 574 m. Lake Cheston.
Growing within 2 m of the ground on the trunk of a large tulip-poplar, Liriodendron tulipifera, on a park-like grassy slope at the shore of a small lake.
In actual size, this little patch of lichens was somewhat larger than a postage stamp.
Note added on 07 Mar 2009: Jason, this was my “Eureka” moment, when I first discovered microlichens. They were on a fragment of bark with a much larger lichen which I was sliding around under the microscope, and all of a sudden … Yikes! … There’s a whole world down there at about 5% normal size!
