Two new species of sequestrate Agaricus (section Minores) from Australia

Original Article

Abstract

The novel species Agaricus lamelliperditus and A. colpeteii are described and illustrated, and affinities to other taxa determined by analysis of ITS sequence data. Both taxa resemble several other recently described Australian sequestrate Agaricus species, in particular A. pachydermus, A. wariatodes and A. chartaceus, which all have a powdery hymenophore from very early stages of basidiome formation. Both novel species have affinities to section Minores.
