Specimens of the genus Spencerisporites have been examined from 42 localities in Europe and North America that encompass a range from Visean to Stephanian. Two principal species are recognized: S. radiatus, which is present from Visean through West‐phalian C, and S. gracilis, from Westphalian D to Stephanian. A new variety of S. gracilis is recognized from Illinois. A transitional gradient in size and morphological characters exists, and significant changes occur at the Mississippian‐Pennsylvania boundary (Namurian A to B) and from Westphalian C to D. The ability to view this continuous stratigraphic sequence reveals the difficulty in obtaining confident demarcation of species
