This volume summarizes the taxonomic and phylogenetic knowledge of asmall group of fungal, mushroom genera (Homobasidiomycota, A garicales)centered in Xerula s.l. and Oudemansiella. Introductory material including published history of the group, application of DNAsequencing and phylogenetics of the taxa invoved, world monographs of the included genera, and studies of type speciemns linked to implicated taxa. Sixty - eight new taxa and / or new combinations are proposed, including four new genera (Hymenopellis, Paraxerula,Pointiculomyces, Protoxerula) and other genera are resurrected /reconfigured (Dactylosporina, Mucidula, Oudemansiella, Xerula).
