Summary
A new wood-inhabiting fungal species, Trullella yunnanensis sp. nov., is described based on morphological and molecular characters. Trullella yunnanensis is characterised by annual, laterally stipitate basidiomata with light brownish hymenial surface and a dimitic hyphal system with clamped generative hyphae and cylindrical, colourless, thin-walled, smooth basidiospores (3.5 – 4.5 × 1.5 – 1.9 μm). Sequences of ITS and LSU nrRNA gene regions of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and bayesian inference methods. The phylogenetic analyses based on ITS and ITS+nLSU sequences in Steccherinaceae showed that Trullella yunnanensis nested into Trullella and then appeared to be the sister clade to all other species of Trullella. Further phylogeny inferred from ITS sequences among Trullella revealed that Trullella yunnanensis formed a monophyletic entity with a high support (100% BS, 100% BP and 1.00 BPP).
