location : Lackawanna county,  PA,  a very rocky slope which is covered with different kinds of Lichen
June 1. 2006
Visiting my favorite slope last weekend I found another interesting Lichen.
I believe this to be:
Cladonia cervicornis ssp verticillata
link to Cladonia cristatella
And another closer look:
The cups are coming out from the center, not the margins. They are forming several tiers. squamules are just about nonexistent.

Consulting my beautiful Lichen Book
(Lichen of North America), I found a perfect picture of the same Lichen with an excellent description, providing a good match.
