Saxicolous species of <i>Claudopus</i> (<i>Agaricales</i>, <i>Entolomataceae</i>) from Australia

Claudopus rupestris , C. viscosus, and C. minutoincanus are described as new to science. All three species produce abundant, white basidiomata on the underside of granitic rocks and have a pileus that is sticky to the touch. Claudopus rupestris has unusual basidiospores, some of which are 4-angled. Claudopus viscosus and C. minutoincanus possess subcapitulate to capitulate pileocystidia and are morphologically similar to Entoloma jahnii of Europe.
