I’m quite sure these are Gymnopilus junonius (aka:Gymnopilus spectabilis). They were found growing clustered together on an old birch tree in a suburban golf course area in Atlantic Canada. Growing directly below them was a patch of smaller dark brown mushrooms with pale thick stems, not sure if they were just very young ones or a different species.

The caps were a yellowy-orange before they were picked, but have now faded to a bit paler, some parts are slightly browner. They are 0.5 inch to 5 inches, I seem to have picked a variety of younger and older. Young ones have rounder, more even caps while larger, older ones are either broadly round or almost flat. None seem to be umbonicate or indented.

Gills are pale to brown, close together and none seem to have a bump or indent where the stem is. The younger ones have a veil under the gills, while the mature ones have only a red/brown ring where the veil used to be. No spore print has been collected.

The stems range from short to long, some are thicker at either end. Usually paler at the top, then brownish at the bottom. None seem to have bruised a noticeable blue, most turn a little brown.

UPDATE: The spore print is reddish cinnamon brown
