Excerpt from A Check List of North American Rust Fungi (Uredinales)<br/><br/>The International Rules of Botanical Nomenclature, previous to the Stockholm Congress of 1950, were ambiguous as to what constituted the basis for setting up names for the rust fungi (uredinales). The 1935 edition of the Rules states (art. 57) that The perfect state is that which ends in the teleutospore or its equivalent in the Uredinales. There was a diversity of Opinion as to whether the uredial stage was to be considered as the equivalent of the telial stage for the purposes of establishing legitimate names for the rust fungi. This situation was cleared up by the Stockholm Congress of 1950 which adopted the fol lowing wording which appears in Article 69 of the International Code of Botanical Nomencla ture (1952) The perfect state is that which consists of spores giving rise to basidia in the Uredinales. This rule definitely relieves Uredo names of any responsibility in the setting up of valid perfect state names for the rust fungi. No basic changes were made in this rule by the 8th Congress at Paris in 1954. Inasmuch as many of the names heretofore applied to the rust fungi of North America have been in fact based on Uredo names, or other imperfect state names, it seems desirable to present a list of names which conform, to the best of our belief, to the provisions of the Code regulating such names.
