Great to know. We don’t have a thorough enough Indiana list to use as a filter, but it’s nice to confirm they grow further west than just Ohio.

Found small grouping in oak/pine woods, east edge of road. NW Arkansas, misty & showers for 1 week, end of Aug. 70 degree days, VERY unusual!!! Cap is wet then dries very sticky, stains fingers very yellow.
Stems very smooth. What color spores to look for?

Regards, dianne
