observation 97004, which was growing a few blocks away in the same kind of habitat. And again this keys out easily to Psathyrella thomii, except that species is described as starting white then aging brown and growing “On bagasse piles from sugar mills in wet places” in Louisiana. It is also supposed to be have slightly shorter and wider spores with a bubble like germ pore, they’re not described as truncate either.
