Nice observation. I have found these before but the colors were not quite this dark. See MO obs. 140929.

Does look like G. castaneus.

This one is usually easy to ID by the hollow/chambered/stuffed stipe that breaks easily. Young specimens have white pores like are seen here. But like you say, Phil, probably not enough info available to get a lot of confidence here.

Just looked again. The one photo shows the interior of the upper stipe. Looks like a shell-like exterior with white stuffing inside. Probably G. catsaneus. I have collected this type in diverse habitat, including under hemlock. Nice call Christian!

Really?

The broken-up orange-brown ornamentation and distinctive look of the cross-section, plus the white pores becoming yellow look pretty spot-on for Gyroporus castaneus (in the Eastern N Am sense).

Checked all of the species you mentioned

but not enough data to make a positive ID.

Was this one bitter-tasting?

Hemlock is where I often find T. felleus. The stipe is always reticulate for this species.

The ones seen here look like the name rubrobrunneus may apply, ie brownish color.

T. badiceps is a mild-tasting brown one that I find in mixed woods. There’s generally brown bruising on the pores with this type. The ones seen here do not show the rich brown color I expect with badiceps. T. ferrugineus is another brown mild-tasting one. I believe I have found both these types in our area.
