*These are not all the most recent names. The newer genera have not been integrated into this checklist. This list includes current names that have been used for the Chicago Region (since 1994); see counties; includes Indiana Dunes region. Some of these names are tentative and need further work to verify the identifications are correct. The observation number is the number of dates that the taxon has been recorded (since 1994). Color coding is based on the first word in the Checklist Status.
Reminder, there are many mushrooms found here that have not been identified to species.
