ABSTRACT
The genus Favolaschia within the family Mycenaceae is characterised by the gelatinous basidiomata with poroid hymenophore and most species inhabit monocotyledonous plants. In this study, many samples covering a wide geographic range in China were examined morphologically and phylogenetically using concatenated ITS1-5.8S-ITS2-nLSU sequence data. Three new species clustering in Favolaschiasect.Anechinus, namely Favolaschiaimbricata, F.miscanthi and F.sinarundinariae, are described. Favolaschiaimbricata is characterised by imbricate basidiomata with pale grey to greyish colour when fresh and broadly ellipsoid basidiospores measuring 7-9 × 5-6.8 µm; F.miscanthi is characterised by satin white basidiomata when fresh, broadly ellipsoid basidiospores measuring 7.5-10 × 5.5-7 µm and inhabit rotten Miscanthus; F.sinarundinariae is characterised by greyish-white basidiomata when fresh, dark grey near the base upon drying, broadly ellipsoid to subglobose basidiospores measuring 7-9 × 5-7 µm and inhabit dead Sinarundinaria. The differences amongst the new species and their morphologically similar and phylogenetically related species are discussed. In addition, an updated key to 19 species of Favolaschia found in China is provided.
