| Sumario: | During a survey of microfungi associated with palms from karst formations, three novel ascomycetes were found from decaying petioles of <i>Trachycarpus fortunei</i> (<i>Arecaceae</i>) in Guizhou, China. Multi-gene phylogenetic analyses based on a combined SSU, ITS, LSU, RPB2 and TEF1α sequence data showed that these collections were affiliated to <i>Brunneofusispora</i> and <i>Neooccultibambusa</i> in the family <i>Occultibambusaceae</i>. A new species <i>Brunneofusispora inclinatiostiola</i> is introduced. It is phylogenetically close to <i>B. clematidis</i> but represents a distinct lineage. Morphologically, it differs from the latter in having immersed ascomata with eccentric, periphysate ostiole and smaller ascospores. Morpho-phylogenetic evidence also revealed two new <i>Neooccultibambusa</i> species, <i>N.</i><i>kaiyangensis</i> and <i>N. trachycarpi</i>. Together with the generic type <i>N. chiangraiensis</i>, they formed a distinct lineage within the genus <i>Neooccultibambusa</i>. Three novel palmicolous fungi of <i>Occultibambusaceae</i> are described, illustrated and notes on their identification are provided. The ecological significance of the new taxa and the phylogenetic relationship of genera in <i>Occultibambusaceae</i> is discussed. |
