Sarcoleotia globosa (Sommerf.: Fr.) Korf is an ascomycete characterize d by stipitate ascomata with a convex apothecium, deep brown to black hymenial surface, greyish brown stipe, and hyaline, clavate, non-to mu lti-septate ascospores. Collections of S. globosa from Oregon, Washing ton, and Colorado, United States are reported.
