During the investigation of xylarialean taxa in China and Thailand, six rosellinia like taxa were collected. <i>Rhizoma</i><i>ticola</i> gen. nov. with type species of <i>Rh. guizhouensis</i> is established based on its morphology and multi-gene molecular data. <i>Rhizomaticola</i> owns no carbonaceous stromata and has black ascospores without a germ slit which are distinguished from those of <i>Rosellinia</i>, <i>Dematophora</i>, <i>Stilbohypoxylon</i> and <i>Xylaria</i>. Five <i>r</i>osellinia like species are introduced based on their morphology, inducing three new species (<i>Dematophora popul</i><i>i,</i><i>Rosellinia thailandica</i>, <i>Ro. vit</i><i>is</i>), one new record for China (<i>Ro. cainii</i>) and one known species (<i>D. necatrix</i>). Their descriptions and illustrations are detailed.
