Pouzarella (Agaricales, Entolomataceae) species from New South Wales (Barrington Tops National Park) and northeastern Queensland, Australia

Ten Pouzarella species are described from New South Wales and northern Queensland, Australia, of which eight (P. albostrigosa, P. farinosa, P. fusca, P. lageniformis, P. pamiae, P. parvula, P. pilocystidiata and P. setiformis) are new to science and two (P. debilis and P. lasia) are reported for the first time for Australia. Phylogenetic analyses of the mitochondrial small subunit rRNA (mtSSU), two variable domains (D1, D2) of the 25-28S large subunit rDNA (LSU), and a portion of the second largest subunit of the RNA polymerase (RPB2) gene support separation of these species into three clades. Morphological characters common to these clades are described, and a key to species based on the characters that are distinct between clades is included.
