contains ~3% of all of Indiana’s old-growth forest. There are beech trees over 400 years old very close to where this was found. I just skimmed “The Genera Midotis, Ionomidotis and Cordierites” and this seems like the most likely species based on size and where it was found, but I’ll check it out under my microscope to confirm.

That’s a start

But this is a species which likely only occurs in old growth forest, and it’s identity should really be confirmed with micro.

^I put a piece of a more recent specimen from the same cluster in KOH and it turned it dark purplish brown.
