biostudies-literatureUnknown104Han LSNational Natural Science Foundation of ChinaMorphological comparisons and multi locus phylogenetic analyses (base on the combined genes of ITS, LSU, <i>rpb</i>2 and <i>tub</i>) demonstrated that three new saprobic taxa isolated from bamboo belong to Cainiaceae. These taxa comprise a novel genus <i>Paramphibambusa</i> (<i>P.bambusicola</i><b>sp. nov.</b>) and two new species, <i>Arecophilaxishuangbannaensis</i> and <i>A.zhaotongensis</i>. The three new taxa belong to Cainiaceae (Xylariales, Sordariomycetes) a poorly studied family, which now comprises eight genera. <i>Paramphibambusa</i> can be distinguished from other Cainiaceae genera in having ascomata with a neck and ascospores lacking longitudinal striation, germ slits or germ pores. The two new <i>Arecophila</i> species clustered in a clade with <i>Arecophila</i> sp. and <i>A.bambusae</i>. Detailed morphological descriptions, illustrations, and an updated phylogenetic tree are provided for the new taxa.MycoKeys113-132https://www.ebi.ac.uk/biostudies/studies/S-EPMC11040201biostudies-literature<i>Paramphibambusabambusicola</i> gen. et. sp. nov., <i>Arecophilaxishuangbannaensis</i> and <i>A.zhaotongensis</i> spp. nov. in Cainiaceae from Yunnan, China.PMC11040201Han LHDai DQHan LSElgorban AMWijayawardene NNLi QLiu CTanaka KPromputtha IAl-Rejaie Sfalse<i>Paramphibambusabambusicola</i> gen. et. sp. nov., <i>Arecophilaxishuangbannaensis</i> and <i>A.zhaotongensis</i> spp. nov. in Cainiaceae from Yunnan, China.Morphological comparisons and multi locus phylogenetic analyses (base on the combined genes of ITS, LSU, <i>rpb</i>2 and <i>tub</i>) demonstrated that three new saprobic taxa isolated from bamboo belong to Cainiaceae.
