ResumoSix penzigioid Xylaria species that are characterized by small, discoid to pulvinate, soft stromata are included in this study. Xylaria albocinctoides, X. bicampaniformis and X. lechatii are described as new; Nummularia albocincta, Hypoxylon carabayense and H. discolor are moved to the genus Xylaria to form new combinations X. albocincta, X. carabayensis and X. discolor respectively. An identification key is provided for the major aggregates of Xylaria that harbor penzigioid species as well as the species of the X. frustulosa aggregate, to which the six studied penzigioid Xylaria species belong.
