There are old Larch needles in the 2nd photo.

I have seen Larch trees near your site, but not exactly at your location: in White River Canyon (Hwy 35) and near Timothy Lake on Hwy 26 about 15 miles SW or your location.

I believe the seedlings in the first photo are Douglas-fir, and likely too small to support the fruiting of such large fungi unless there are many many more such seedlings all tied into the same mycorrhizal net. There are old larch needles in your second photo, I believe.

that can be seen in the first two photos, they do look like larch! I just noticed.

Will check

The next time I’m there, I’ll check if there are any larches around.

The books mention bitter taste, but I cannot confirm that either.

any Western larch may have been just seedlings, and not much noticeable. I think F. ochraceoroseus is said to be found only with Larix, right? Growing under larch is a little misleading: if there was a mature 200-ft tall larch tree 400 ft away, the fungus could still be mycorrhizal with the roots. Only recently as we realizing a host tree needn’t be even nearby.

These were growing in the sand, under the log bridge over Clark Creek, near the beginning of the Elk Meadows Trail. I ID’d the mushrooms only when I got home and learned that they normally grow under larches. I don’t know if there were any larches close to this bridge. I don’t think there were any trees really close to the bridge.

Thank you so much for posting these photos!

I have collected lots on Mt. Hood, and have never seen this species before, nor heard of reference to it. May I ask what part of the mountain you were at?
