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.

Clinker fungus on Yellow Birch

This hard, black plug looks like a big chunk of burnt charcoal. The internal rot caused by the clinker fungus can be 1.5-1.8 meters above and below the conk. Birches are the target of these odd fungi. The wikipedia entry indicates that this mushroom has long been used in folk medicine as a cure for a number of ailments. Would you try it?

Spine tooth fungus on Sugar Maple

Large, soft, smelly conks bloom from the cracks and seams of a sugar maple. The fruiting body of the spine tooth fungus is a delicate beauty; external evidence of a devastating internal rot caused by hyphae that can stretch up to 5 meters above and below the external fruit. Maples attacked by spine tooth will rapidly degrade, and should probably be removed.
