Cormophyton mazonensis gen. et sp. nov. is proposed for an authigenically preserved cormose lycopod base in Mazon Creek nodules from the middle Pennsylvanian of Illinois. Based on size, shape, and morphological features, Cormophyton is assigned to the Chaloneriaceae and is thought to represent a plant similar to Chaloneria cormosa. The discovery of this form allows for the description of several external features of Chaloneria-like plant bases and further demonstrates the diversity of isoetalean lycophytes in Carboniferous sediments.
