When: 2008-10-09

Collection location: Forest near Elgin St., Pembroke, Ontario, Canada [Click for map]

Who: Paul Derbyshire (Twizzler)

No specimen available

Looks like a crust-type polypore. The ragged, broken-up pore-like surface is brown, but there’s a greenish fringe. Found on a stick under both pine and birch.

Third photo shows how patches of it grow all over the branch.

No projecting caps, brackets, shelves, or anything like that were in evidence.

There’s Abies balsamea, Betula allegheniensis, Betula papyrifera, Tsuga canadensis in the vicinity of where this was found, and possibly Picea. Also, observation 21400 looks similar.

I think there were spruce in the area, so Picea is not out of the question.

I dare not propose a name, but I have a feeling that this could be the very rare one that I have wished to find in northern Scandinavia: Inonotus subiculosus! It was first described from Copake, New York State, by C. H. Peck..
It is known to grow on Betula, Picea and Picea in Scandinavia, but also on Thuja, Pseudotsuga and Abies i North America. Is sometimes also craws over mosses and stones..
