It was originally described from coastal Oregon under pine, but I have not seen it.” Pretty close to the known fruiting area.

Thanks for the input! I would like to point out that Peck describes the lamellae of Hygrophorus marginata as "yellow"and the stipe as “pale yellow”. It seems like the concept of this species has evolved over the years and I wonder if Singer was looking at another species all together.

Hopefully maynardjameskeenan can collect and store some specimens in the future.

It’s not H. marginatus (based on yellow, not orange gills, and paler cap and stipe, as well as biogeography), but it might be something near it.

The SVIMS link has a description to H. m. var. olivaceus that describes what might be a similar entity, but it’s hard to know without a photo.

Really neat. I’d love to get a good dried collection.

This thing is outrageously weird and cool.
I have spent plenty of time looking at Hygrocybe of the redwood coast, and this doesn’t really match anything I’ve read about or seen.

If you see it again, try and dehydrate a couple specimens and save them.

Good find!
