*The law of priority needs no straining to adopt this name instead of the 

 more commonly used Myxomycetes. It was proposed by Fries, in 1829, four years 

 previous to the use of Myxomycetes by Wallroth (1833). The additions to the 

 catalogue here given are taken from Morgan's Papers and from Lister's 

 "Mycetoza," published in 1894. This latter author makes many changes in 

 nomenclature and reduces many species to the rank of synonmys. Whenever 

 in his list of localities Ohio is mentioned, it is included in these additions.
