Arora describes as “…crowded, adnate to adnexed or notched.” Also, Arora has this under Armillaria ponderosa. The names of mushrooms change dramatically over time. With the advent of cheap DNA tests, the names are likely to change again.

You should find loads of other photos here on MO, just type the name in the find box at the top of the page.

What you call Scrub pine is likely the low-growing form of Lodgepole pine. Needles in 2. Small cone. Usually growing in sandy conditions. Scientific name Pinus contorta.

Most Amanitas have some color. The ones you are interested in distinguishing grow in sand, often with Lodgepole pine, and are white. Amanita silvicola and A. smithiana can lose the top warts easily in heavy rainfall. Last one is Amanita baccata, usually found in sandy conditions, often with a cap partially covered in sand. Getting the sand off can dislodge any volval warts. Usually fairly small for Oregon Amanitas. Search for each of these on MO for more photos.

The gills are NOT free… I compared them to a chart I found, and it looks like subdecurrent, or adnate… But for sure, NOT free.
These were under “Scrub Pine” on the dunes. I looked that up, and that is the pine all around the area I picked them.
I smelled them. They have a full smell, like a mushroom, plus another smell that I can’t say for sure smells like red hots… But I may be too literal about these things.
I have seen and photographed Amanita mushrooms. I have seen them from yellow, to deep red. I recognize the “warts” from that type.
No warts on these mushrooms.
I saw a nice red Amanita coming up yesterday… I could go back and smell it, to determine the difference, or lack of difference in the smell, when I run my Border Collie, today.

Congrats, algoresessister!

This is the famed matsutake (Japanese for pine mushroom)! Incredibly edible. It should have an odor of cinnamon red-hots and dirty socks. The active incredient, cinnamomeum, is also found in cinnamon. For diabetics like myself, this is one of the best possible mushrooms to find.

These really like sandy soils and usually are associated with Lodgepole pine (Pinus contorta). North Bend and the area further north would be expected to have many of them.

The only fungi you want to be worried about when picking T. magnivelare are the Amanita mushrooms. These may (but sometimes don’t) have white patches on top of the cap. They may (but sometimes don’t) also have a volva or cup-shaped structure near the base of the stipe. So when picking T. magnivelare it is important to excavate a little to be sure you have the lowest attachment possible for the mushroom. Amanita smithii is especially difficult to distinquish from some T. magnivelare. Just so you are aware of the problems.
