Stony Brook, Harriman - Jul 25, 2026

After two consecutive summers of drought, we have finally experienced good rain around Sloatsburg, and with it, a tremendous number of mushrooms we haven't seen in a while. There were also mushrooms never-before-seen. Morgan found Balansia hypoxylon, a member of family Clavicipitaceae which infects grasses —this one was on Danthonia. ~30 people on a ~4 hr. walk
