Abstract

Several micro fungi were gathered from bamboo and palm in Guizhou Province, China. In morphology, these taxa resemble Neomassaria, Roussoella and Oxydothis. Multi-gene phylogenetic analyses based on combined ITS, LSU, SSU, rpb2 and tef1 loci confirmed that two are new geographical records for China, (viz. Roussoella siamensis, Neomassaria fabacearum), while two of them are new to science (viz. Oxydothis fortunei sp. nov. and Roussoella bambusarum sp. nov.). The stromata of Roussoella bambusarum are similar to those of R. thailandica, but its ascospores are larger. In addition, multi-gene phylogenetic analyses show that Oxydothis fortunei is closely related to O. inaequalis, but the J- ascus subapical ring as well as the ascospores of O. inaequalis are smaller. Morphological descriptions and illustrations of all species are provided.
