Observation 21323: Trichaptum biforme (Fr.) Ryvarden
When: 2009-05-25
No herbarium specimen

Notes: White polypore on fallen deciduous branch in an area with Black Spruce (Picea mariana), Eastern White Pine (Pinus strobus), Jack Pine (Pinus banksiana), Paper Birch (Betula papyrifera), Quaking Aspen (Populus tremuloides), Red Maple (Acer rubrum), Red Pine (Pinus resinosa), and possibly unidentified trees.

Branch was nearer to birch than any other species of broadleaf tree.

Brackets slightly off-white, zoned, forming shinglelike colonies, downcurled at the sides in a distinctive way, with cream pores that are browned and ragged in places.

that this shape was a coincidence.. Both remind of Gloeoporus dichrous.

Not sure

Not sure, though growth habit looks different. The curling down of the sides of the fans, until some are almost tubular, is distinctive here and lacking in 21322.

No idea
