Discussion:

On bark of Jacquinia keyensis, vicinity of The Bight, Cat Island (Britton and Millspaugh, March 1-6, 1907, 5849, type). The white epiphloeodal thallus and the shining globose perithecia will serve to distinguish this from the few species of Microthelia having four-celled spores, such as 11. thelena var. subtriseptata Wainio.
