Very local. In addition to my specimens it has been reported from Lake, Montgomery, Porter, and St. Joseph Counties. One of my specimens is from a small colony at the base of a north beech slope, bordering a soft maple swamp, and the other is also from a swamp bordering a lake. My specimens are not typical and seem to be intermediate between the species and the var. dendroideun (Michx.) D. C. Eaton.
