Morphological and molecular analyses reveal two new species of Termitomyces (Agaricales, Lyophyllaceae) and morphological variability of T.intermedius.

ABSTRACT: Two new species, Termitomycestigrinus and T.yunnanensis are described based on specimens collected from southwestern China. Termitomycesyunnanensis is morphologically characterized by a conspicuously venose pileus surface that is grey, olive grey, light grey to greenish grey at center, light grey towards margin, and a cylindrical white stipe. Termitomycestigrinus is morphologically characterized by a densely tomentose to tomentose-squamulose pileus showing alternating greyish white and dark grey zones, and a stipe that is bulbous at the base. The two new species are supported by phylogenetic analyses of combined nuclear rDNA internal transcribed spacer ITS1-5.8S-ITS2 rDNA (ITS), the mitochondrial rDNA small subunit (mrSSU) and the nuclear rDNA large subunit (nrL
