Yellow cap fungus on Sugar Maple

Yellow cap mushrooms look like yellow fairytale toadstools, and yes, they are up to no good! These sticky shrooms will take advantage of an already wounded tree, leaving yellow-brown, stringy rot in their wake. The yellow cap generally prefer maples and yellow birch. Add that to the list of parasites that love maples!

Coal fungus on Sugar Maple

These crusty black fungi almost look like they were painted on! It's hard to imagine them being attached to internal rot causing hyphae 1-2.7 meters above the conk, but they are! Maples and beech are targeted by the coal fungus.
