I looked up this species in the voucher photos for Mycoblitz, too…

Darvin’s fresh material with its yellow cap had faded to white, losing most of the yellow color. Interesting. We’ll definitely want to pick any whitish Hygrocybe mushrooms under redwood and check for those brilliant yellow gills!

Rare….or rarely collected? Thanks for the head’s up, Christian! And it’s looking to be a good spring for hygrocybes…

Oohh… nice one.

Cool find there, nice one… I only saw this once, and it was the collection that Darvin posted. I took my own photo of that collection, but I’ve never found this one myself…

Forgot to mention –
In a gulch surrounded by many Hygrocybe punicea (interesting!), nearest trees were oak and tanoak (including one killed by SODS); Douglas-Fir and redwood farther away.

and it looks like you have the only decent photo of it, for the three collections…
