Two new species of Geejayessia are introduced, based on materials collected from central China. Geejayessia clavata sp. nov. is characterised by gregarious, red brownish to dark red, oval-subglobose to globose perithecia that are formed on a basal stroma; (4–7-)8-spored cylindrical asci; ellipsoidal or rarely broadly ellipsoidal, uniseptate, smooth or finely verruculose ascospores; clavate, aseptate microconidia and absence of macroconidia. Geejayessia sinica sp. nov. is characterised by red to bright red, pyriform, subglobose to globose, perithecia on a basal stroma, collapsing laterally when dry; subcylindrical to clavate asci with a rounded apex; ellipsoidal, uniseptate ascospores; and falcate, multiseptate macroconidia with an arcuate tip. Morphological distinctions of the new species from the related fungi are discussed. This is the first report of Geejayessia from Asia.
