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.

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.

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.

a defunct genus name?

Hi Dave,

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

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?
