not sure why this got “popped”…

but this is exactly what Pycnoporellus alboluteus looks like when it fully “flowers” in the PNW.

In more xeric montaine conditions (the Sierra, Montana, etc.) it is merely a shadow of itself…stunted and small. Like this one, here:

a better photo?

Texture would matter, I cant feel the specimen in the photo, but I have seen innumerable Hericium caught by a wet frost in BC that look much like the image here. Of course reconstructing from a single image is sketchy, my confidence level will change with multiple images. My experience with P. alboluteus in Montana is quite frequent, it turns up as a snowmelt fungus on downed logs frequently. The morphology with which I am familiar is shown on www.fungaljungal.org under Scientific Info/Family Listings and Polypores. I do apologize for the cumbersome nature of this site now, but Im short of funds to pay for the needed modernizations. The pores are large and somewhat irregular on the edges, but primarily resupinate on the log, and papery to corrugated-cardboard like in texture. the specific name results from the original dried herbarium specimens fading to white before they were examined & recorded.

I agree Irene.

if this is the way it should look when it gets the chance to grow out completely..
I have only seen in live once, and a few pictures of it from my area (on large spruce logs), but not with such flaring pores. So, I think the habitat here (or climate) simply isn’t the best possible for it.

well Larry…

meet Pycnoporellus alboluteus. I know Hericium and this is no Hericium! :)

We see this stuff at melting snowline in MT every spring, and sometimes into the fall, on fallen logs. the pores are large and irregular diamond shaped, the organism has a color like the bright red Pycnoporus we see across the continent, except it is more orange. It fades in sunlight, and in old herbarium collections. Check the fungaljungal.org website for images.

I have two sightings of this mushroom two years apart…

Ooops! I answered your question on the other one, here…

This can’t be its ordinary form, can it? A conidial stage?
