Abstract
Australian collections of sequestrate Agaricaceae were examined with morphological and molecular data (nuclear DNA from ITS and LSU), and the majority were found to belong to the genera Agaricus and Macrolepiota. Previously described Australian species of Endoptychum are transferred to the appropriate agaricoid genera and several new combinations proposed. Descriptions and illustrations are provided for these and eight new species: Agaricus eburneocanus sp. nov., A. chartaceus sp. nov., A. erythrosarx sp. nov., A. inilleasper sp. nov., A. pachydermus sp. nov., Macrolepiota gasteroidea sp. nov., M. vinaceofibrillosa sp. nov. and M. turbinata sp. nov. The sequestrate genus Barcheria is retaine..
