Wood-inhabiting fungi play a fundamental role in ecosystem processes, particularly in wood degradation and the recycling of organic matter. In this study, a new genus, Clavuliella gen. nov. , and five new species, viz. Burgella albofarinacea sp. nov. , B. fissurata sp. nov. , Burgoa wumengshanensis sp. nov. , Clavuliella sinensis sp. nov. , and Sistotrema sinense sp. nov. , are described from China and illustrated based on morphological characteristics and molecular phylogenetic analyses. Sequences of the ITS+nLSU genes were used for the phylogenetic analyses using Maximum Likelihood, Maximum Parsimony, and Bayesian Inference methods. The phylogram of the family Hydnaceae, based on the ITS+nLSU rDNA gene regions, included four genera; Burgella , Burgoa , Clavuliella and Sistotrema. The topology based on these sequences revealed that Burgella albofarinacea was closely related to B. flavoparmeliae , and B. fissurata was grouped with B. lutea . The taxon Burgoa wumengshanensis was sister to the clade that included B. anomala and B. verzuoliana . The species Sistotrema sinense was grouped closely with S. brinkmannii and S. farinaceum . All new taxa can be readily recognized by their macroscopic and anatomical characteristics. The five new species, closely related taxa in the phylogenetic tree, and morphologically similar species are discussed.
