This does not have the really spongy looking stipe that I normally see on H. spongiosipes. It also looks like there is a bit of bruising on the edges. Spore size would help. I’m not sure which this is.

Hardwood Host probably

Hi Tom,

This one was found on a mossy ridge top with mostly oaks and a few pines. I do not recall seeing pines in the immediate vicinity, and there are no needles in the photo, but pines were growing in the general area. If I had to guess I would say this mushroom has a hardwood host.

Hi Dan. Hydnellums everywhere! I suspect this is Hydnellum spongiosipes. Here’s another dichotomy from Sean Westmoreland’s thesis.

25. Growing under pines or other conifers; pileus tomentose; staining brown when fresh where bruised, context of pileus and stipe not deeply duplex, usually with light-colored zone lines and mottling; spores 5-6 × 4-5 µm

H. ferrugineum (=H. pineticola)

25. Growing under deciduous tress, mainly oak; pileus and stipe spongy tomentose; not as easily bruising brown when handled fresh; context of pileus and stipe deeply duplex, lacking light-colored zone lines and mottling; spores larger, 6-7 × 5-6 µm

H. spongiosipes

Nice Darv!

You got it without even seeing the teeth! Will upload a bottom side shot here in a bit. The shot of the teeth did not make it into this batch of photos.

Looks like it might be a young Hydnellum. Did you get any photos of the spore surface?
