Morphological and phylogenetic analyses reveal a new species of Fistulina (Fistulinaceae, Agaricales) from Australia

A new species of Fistulina, F. tasmanica sp. nov., is described and illustrated from Tasmania in Australia. Fistulina tasmanica is distinguished by its pileate and fleshy basidiomata with rose pore surface, fibrous context, separated tubes with small pores (6-7 per mm), a monomitic hyphal system with only clamped generative hyphae, subellipsoid to ellipsoid basidiospores (5.4-6 x 3.4-4 mu m) which are negative in Melzer's reagent and cotton blue. Phylogenetic analyses inferred from the internal transcribed spacer regions (ITS) and the large subunit of nuclear ribosomal RNA gene (nLSU) sequences also confirmed that F. tasmanica is a new member within Fistulina.
