Untangling the () species complex in Australasia.

The complex is a commonly observed, generally brightly coloured, group of mushrooms that are usually associated with or Myrtaceous hosts in Australia and New Zealand. For this study collections labelled as '', '' and '' were examined morphologically and molecularly. Analyses of molecular data showed a high cryptic diversity, with sequences scattered across 11 clades in three subgenera within , and a single collection in We select epitypes to anchor the currently accepted concepts of s.str. and s.str. The name could not be applied to any of the collections examined, as none had a lamprotrichoderm pileipellis. var. is raised to species level, and six new species are described, three in subg. : , , and , and three in subg. , , and . A new collection of provides a significant range extension for the species. Untangling this complex will enable better identification of species and increase understanding of diversity and specific habitat associations of macrofungi. : Lebel T, Douch J, Tegart L, et al. 2021.
