A new ascomycetous species, Neokalmusia didymospora, inhabiting dead bamboo, is introduced based on morpho-molecular studies. Neokalmusia didymospora is characterized by orange to brown clypeus, immersed, subglobose ascomata, bitunicate, cylindrical asci and 1-septate, brown ascospores. Maximum-likelihood and Bayesian analyses of combined SSU, ITS and LSU gene sequence data show that N. didymospora belongs in Didymosphaeriaceae, Pleosporales. The new species is compared with other morphologically similar and phylogenetically related species.

Keywords: Dothideomycetes, ITS, LSU, SSU, taxonomy.
