The starting point in the nomenclature of the Gasteromycetes is Persoon's Synopsis A1 ethodica Fungorum of 1801. Many of the specimens on which Persoon based his descriptions are in his herbarium, which is now in the Rijksherbarium at Leiden, Netherlands. Perdeck (1950), as a result of his study of Persoon's herbarium, made some name changes in an attempt to clear up some of 1 he nomenclatoral confusion existing in the Lycoperdaceae. In a previous paper Garner (1955) incorporated these changes in making a revision of the genera Calvatia and Dycoperdon as treated by Kambly and Lee (1936) in "The Gasteromycetes of Iowa". The following keys incorporate these name changes. This work was done in the mycological laboratories of the State University of Iowa under the direction of Professor G. W. Martin.
