Evernia Mesomorpha with Apothecia

Evernia mesomorpha rarely produces apotheica. On April 29th, 2013 I observed this thallus in Michigan's Upper Peninsula at Point Aux Chenes dune/swale complex just west of St. Ignace.

Substrate: The bark of a fallen black spruce tree.

Evernia prunastri grows in the western US and in Europe. Apothecia on e. prunastri is as uncommon as e. mesomopha.

Note: Evernia prunastri was thought by some to be extirpated from Michigan. I observed the Evernia mesmorpha with apothecia on April 29th 2013 and on April 13th I observed Evernia prunastri in the upper peninisula of Michigan.

Here is a link to my documentation of E. prunastri in Michigan.
