different species

P. erinaceus and F. erinaceellus are two different species.
erinaceus is a European name, F. erinaceellus is a Peck name…

Nice pics Dan

Flammulaster erinaceellus is the current name for this one I believe.

Just did a Google for P. erinaceus

and found what appears nearly exactly the same fungus as what I have found locally in Oregon. Sole difference that I can tell is that the gill edges are often white. Have not found any description of white-edged gills for Phaeomarasmius, but maybe I’ve got a different variety?

Cap warts?

What is the ornamentation on the cap? Are they warts or stylized hairs? I believe I have collected this in Oregon as well, but had absolutely no clue as to what is was. Nor could I find a mycologist in the house willing to suggest anything. The cap ornamentation, scurffy/scruffy stipe, small stature (at least for my material, less than 2 inches tall), growing from rotted wood, and the tawny to golden-brown gills should have made this an easy ID. But I nebver could find anything close. Now I’m hearing the name Phaeomarasmius – which I have never heard of before. Glad to have something to check, but are there any citations available?

Check Google

Just click on the Google images link, there are quite a few photos of Phaeomarasmius erinaceus online. It seems to be an almost common ’shroom in Europe, but very rare in the US (if it is even the same species).

It would be good to know the spore color here though… And was the cap surface grandular or spikey (does surface granules come off when you brush it)?

Pholiota grandulosa

They reminded me of Pholiota grandulosa, which is common here, but they were a bit shaggier than the ones I usually encounter. I don’t know about Phaeomarasmius erinaceus I can’t find a good picture for comparison.

Why Pholiota here?

Are you suggesting Pholiota because this one had a brown spore print? Or just from the scaly stipe? Pholiota should also have a slimy, gelatinous layer on the cap surface.

If this is brown spored, there is Flammulaster or perhaps Phaeomarasmius that might be a better match.

But if it isn’t brown spored, there is a mid-west mushroom that is closer to this, take a look at Leucopholiota decorosa.

Just some suggestions…

The veil adhering to the edge of the pileus may suggest Cystoderma, as well as the scruffy stipe. But the gills look too colorful – unless it’s a new Cystoderma to me.
