Paramphisphaeria is described as a new genus on the basis of the single species, P. costaricensis. It differs from Amphisphaeria spp. primarily in having bicellular ascospores with a germ slit and in having an ascus apical ring that does not become blue in iodine. It resembles Amphisphaeria in its brown color and lack of constriction at the septum of the ascospore. An anamorph is unknown. It tentatively is placed in the Xylariaceae for reasons discussed. Pachytrype rimosa is described as a new species.

Key words: Ascomycetes, Calosphaeriales, Diaporthales, pyrenomycetes, Xylariaceae, Xylariales
