I am a little free and easy with the titles (although mold is a fungus)…this isn’t very moldy, but it sure is sweaty. The bracket fungus Red-banded Polypore (Fomitopsis pinicola) aka Red-belted Conk quite often exudes sweat-like moisture (guttation) in the heat of the summer. I have only seen this fungal species do this but it is quite common in green plants and found on the tips of leaves.
Near Kidney Pond in Baxter S.P., Northern Maine.
Here’s a small button of a conk forming on a pine near Jordan Pond in Acadia N.P., coastal Maine.
Obviously, it is too early to find sweaty mushrooms, but with some luck it won’t be too long a wait.
