On Maple.

G.tsugae normally grows on conifers such as hemlock, but has also been reported from birch. I have seen people post to forums finding it on maple, but this is the first time I have found it in person growing from maple. One half of the tree was still alive and had leaves on it, allowing a definitive ID, I could not get a decent picture of the canopy so I picked a leaf up from the ground matching those from the branches. No conifers were seen in about a mile or so of miking in this particular forest.
