Collection location: Clinton, Whidbey Island, Island Co., Washington, USA [Click for map]

Who: Sam Linse (BearwoodSam)

No specimen available

Found on dead coniferous wood in small groups in mature mixed coniferous second growth forest of Douglas Fir, Western Red Cedar, Western Hemlock.
Cap is orange brown about 4 to 6cm in diameter.
Gills are mocha brown, very coarse almost like ridges, forked, attached and very widely spaced.
Stem is reddish brown, equal and has small sparse cream colored hairs or scales.
I thought it might be a Phylloporus rhodoxanthus, but doesn’t seem to match photos of them?

I agree with Hypholoma. That is exactly what they look like when they get old. Concurrently, when they get nasty, old, and waterlogged, the lamelle mat together, as perfectly exemplified in the last photo.
It is certainly not any parasitized mushroom. Just some old and rotting Hypholoma species.

Still not convinced this is Hypholoma fasciculare, and I may never know for sure. However I went back to see this bunch a week later and found them almost completely gone. Looking again at all the gills I can’t help but think this has been parasitized by another fungus. The gills on one cap were fairly normal free gills, but the rest were all these flat radiating forked ridges. Ring any bells for anyone. I’ve added another picture to illustrate. Thanks!

Hypholoma fasciculare huh?

I do have lots of H. fasciculare around, but none looks like this I’m sorry to say. Even old as it is they seem really quite different. The gills are quite widely spaced in this specimen and not so in Hypholoma fasciculare that I have encountered. I will investigate them further to see if I can get some more identifiable features. Thanks!

Hypholoma sp.?

The yellow-green tones and the dark spore color and the general stature make me think this is either Hypholoma fasciculare or H. capinoides. However, these are too old to visually distinguish between those two species.

These look to be old, wet Hypholoma fasciculare, they should coming off of rotten wood, but sometimes the wood has dirt over it, also they should come from a grouping at a single point, but sometimes they get broken up.

But anyway, the brown with yellow-green tones, and the dark gills in age, with a grouping of caps, point to this species.
