Phylogram generated from Maximum Likelihood (PhyML ver 3.0) analysis based on ITS sequences of Agaricus from the sections Agaricus, Sanguinolenti, Spissicaules, Arvenses and Minores (Lebel and Syme 2012; Zhao et al. 2011). Maximum Likelihood bootstrap support values greater than 50 % are indicated above the nodes, and branches with Maximum parsimony bootstrap support values greater than 75 % are given in bold. The type species are given in bold; the new specimens are in blue. The tree is rooted with Barcheria willisiana
