摘要： Two new Neofomitella species, N. australiensis and N. guangxiensis, are described based on morphological and molecular characters. Neofomitella australiensis is characterized by white pore surface when fresh, dextrinoid skeletal and binding hyphae, and orange-red context near pileal surface when fresh. Neofomitella guangxiensis is characterized by round to angular pores (5-6 per mm), weakly dextrinoid skeletal and binding hyphae and large basidiospores (5.5-7.5x1.8-2.2m). Phylogenetic analyses were carried out based on sequences from the internal transcribed spacer (ITS), the large subunit nuclear ribosomal RNA gene (nLSU), the small subunit nuclear ribosomal RNA gene (nSSU), the small subunit mitochondrial rRNA gene (mtSSU), the translation elongation factor 1- gene (EF1-), the largest subunit of RNA polymerase II (RPB1) and the second largest subunit of RNA polymerase II (RPB2), and the result confirmed the affinities of the two new species within Neofomitella. An identification key to species of Neofomitella is provided.
