biostudies-literatureUnknown13Lu W<h4>Background</h4>Yunnan Province, recognised as a biodiversity hotspot in China, is a rich source of fungal diversity that we are just beginning to explore. During our investigation of bioluminescent mushrooms in this region, we collected four specimens from the family Mycenaceae. We conducted morphological characterisation, multilocus phylogenetic analyses (ITS, LSU, SSU, <i>tef</i>1-α and <i>rpb</i>2) and photographed specimens under completely dark conditions.<h4>New information</h4>In this paper, we report on two bioluminescent mushrooms of Mycenaceae collected in Yunnan Province, China. Morphological and phylogenetic analyses revealed <i>Mycena semivestipes</i>, which was first observed with bioluminescence and <i>Roridomyces pruinosoviscidus</i>, which has not been previously recorBiodiversity data journale168858https://www.ebi.ac.uk/biostudies/studies/S-EPMC12780892biostudies-literatureHidden in the daylight: A polyphasic approach reveals two bioluminescent Mycenaceae species from Yunnan Province, China (Basidiomycota, Agaricales).PMC12780892Dai DQLu WElgorban AMAlfagham ATSuwannarach NTibpromma SChukeatirote EKarunarathna SCKumla JfalseHidden in the daylight: A polyphasic approach reveals two bioluminescent Mycenaceae species from Yunnan Province, China (Basidiomycota, Agaricales).<h4>Background</h4>Yunnan Province, recognised as a biodiversity hotspot in China, is a rich source of fungal diversity that we are just beginning to explore.
