Used references: Audubon documents P. erinaceellus, and this looks like a decent fit for the obs, except that the one seen here shows more overall yellow. MO species bank lists several other Phaeomarasmius species.

Errata and Interpretations

Hey Dave, good catch. Don’t know why I said white spored. I will chalk it up to extreme fatigue, but it is more likely due to pervasive ignorance. All of the taxa we’re considering have some flavor of brownish/pigmented spores.

The important bit is this: there are multiple interpretations of Flammulaster/Phaeomarasmius, and I assign granular-looking mushrooms to the former, fibrillose ones to the latter.

From MycoKey/Funga Nordica:
“Chains of globose cells in the epicutis match Flammulaster sensu Vellinga but this is not a delimiting character in Horak’s system.”

Like any good Californian, I follow Vellinga. Maybe that should be a bumper sticker.

Thanks Christian.

I asked because Kuo reports that the species formerly known as Phaeomarsmius erinaceellus is now in the genus Flammulaster. This is not a white spored mushroom. Audubon calls the print color “dingy cinnamon.”

Here’s a link to what one source calls Phaeomarasmius erinaceus (same species as my previous note?). This one is reported to have reddish brown spore print. The link shows a photo of a specimen which has the marginal veil remnants.

I suppose that the problem may be that “Phaeomarasmius” no longer has the same meaning as it did when the Audubon guide was compiled.

Genus

Phaeomarasmius is not defunct (As far as I know). It includes often dark-pigmented, rather small, brown-spored corticolous bark agarics that are shaggy-fibrillose all over.

This species looks more like a Pholiota (similar to what we call P. flammans) than it does like a Flammulaster. The latter genus tends to have more round-cyst-like (and thus pulverulent, friable, granular-looking) caps and stipes, rather than the shaggy-fibrillose stipe shown by this species.

I also don’t know of any Flammulaster that would show such adherent membranous veil remnants on the cap edge as this specimen.

Is Phaeomarasmius…

a defunct genus name?

From Elm I think

Hi Dave,

This little yellow mushroom was on a backless fallen log, which was straddling a dry creek bed. I think it was Elm.

Wow, that’s a nice one, Dan!

Serrated gill edges and dry shaggy/scaly stature reminds me of Leucopholiota decorosa, which is of course ruled out by gill color. Maybe it’s a Flavoleucopholiota :-)

Any info on habitat?
