Well‐preserved fresh‐water algae, fungi, and parts of insects have been described from the rich oil shale beds of the 50‐million‐year‐old Eocene Green River Formation of Wyoming, Colorado, and Utah. Recently the sporangia of two additional aquatic fungi, both members of the Chytridiales, have been identified. These sporangia are so nearly identical with those of living species of chytrids ( Entophlyctis lobata Willoughby and Townley and Pleotrachelus fulgens Zopf) that they are assigned to these two genera. E. willoughbyi and P. askaulos are established as new species. Because of the “mummified” condition of these fossil chytrids, the inferred fossilization process is discussed briefly.
