MO hosts dialogue between some rather audacious mycophiles, especially when we’re talking LBMs. ;)

Cool reference page, you collected those in Bulgaria??

I rarely bat an eye at the proposal of a species or genus outside of its documented range… There are many possible explanations- could result from spores or mycelium transported across sea via potted plants and people. Might also be that the species has been over looked for that long (especially with such a tiny mushroom), or that it is a closely related, undocumented species.

I believe other Phaeomarasmius species have been reported from the West Coast, but I’m not sure about P. erinaceous.

I found a Flammulaster in Salt Point a couple months ago, but accidentally threw it over my shoulder… Alan made an observation for it. Nathan and Mike Wood have also found them. Which species, I’m not sure:

Here is a Reference Page on Phaeomarasmius erinaceus that I just put together

You guys are flirting with some pretty interesting Genera for the West
Coast — this would be a nice collection to nail — has it ever been
recorded out West? Otherwise, it does look like it, qiute a lot, but
we need to prove that.

Here is a Reference Page on Paeomarasmius erinaceus (European
collection) that I just put together for you — preped a quick slide,
so its not very pretty, but should do the job. The micro
characteristics are very straight forward and easy to verify.

1) LARGE SPORES, ellipsoid to broadly so, variable: 8-14 × 7-9µ

2) Basidia, MAINLY 2 SPORED, sometimes 3.

3) Cheilocystidia forming a sterile band, cylindrical to moliniform,
some lageniform to utriform, flexious ~30 (/- 10) x 6 (/- 2)µ

Granular stipe and cap

Did you get this under the scope, and try to look for the granular cap and stipe surface tissue? Making sure of a Phaeomarasmius obs. from CA. would be good. I’m not sure I’ve heard of this one from the west coast, although I think it is common enough in Europe, and somewhat found in the northeast US.

if color and spikiness(cap and stem) are sufficient to bring it to sp., I vote with Else!

Phaeomarasmius erinaceus

The dark red-brown fruitbody and the spikiness of the cap and stipe point to Phaeomarasmius erinaceus.
Flammulaster muricatus is goldenbrown, and granular on stipe and pileus.
Also the habitat on twig points to Phaeomarasmius.

It should be noted that the genus Flammulaster was previously considered Phaeomarasmius, and have since been distinguished as separate genera.

could be Phaeomarasmius…

further scope work will tell the tale.

I think Darvin got it

I’ve only seen Phaeomarasmius erinaceus twice, NEMF at Mount Alto, PA in 05 and NEMF 99 in ME. both very dry years.

Looks a lot like a darkened Phaeomarasmius erinaceus.
