Observation: Agaricales sp. Underw. (13010)
About Agaricales Underw.
Public Description (default) [Edit]
When: 2008-10-21
Collection location: Larch Mountain, Multnomah Co., Oregon, USA [Click for map]
Who: Daniel B. Wheeler (Tuberale)
No herbarium specimen

Notes: White gills, deep rooting stalk about 6.5 inches long, twisted, fibrous, with yellow-tint to stalk, especially that portion underground; cap 3.5 inches across, mostly white, some fine fibrils, especially near the edge of the cap; center depressed and somewhat reddish-stained; gills pure white; probably growing in well-rotted wood, but hard to tell in that area because wood was everywhere anyway. I was thinking Oudemansiella or similar fungus, but this doesn’t key out easily in Aurora: mostly because of the yellow tint to the stipe, but also that long tapering mostly underground stipe. I had no idea it was going to be that long when I started digging it up. I’m still not sure I got the whole thing.

Summary: Of course it is

though it will take at least one other vote, and/or votes against “Agaricales sp.”.

Perhaps the site should count votes for a larger clade towards an enclosed clade…

Re: my earlier remark, I was not meaning to suggest that this actually might be Oudemansiella radicata, but rather that the specific feature of “has a long rooting stipe” was not inconsistent with Oudemansiella as seemed to have been suggested at the time.

Summary: I’ll accept Rhodocollybia maculata

especially with two such expert opinions. (Always like to get more than one – for everything if possible). Shall I destroy this observation and then rename it? Or does someone want to name it possitively themselves? Is that even possible with the Agaricales naming?

Summary: Rhodocollybia maculata

I agree with Irene – Rhodocollybia maculata is what comes to mind. Sometimes the red stains are not present in west coast material.

Summary: No basal mycelium

at the soil level for this fungus. At least the bottom half of the root is completely buried.

Summary: White gills

A Phaeocollybia with white gills, wouldn’t that be a Rhodocollybia then?
It reminds a lot of Rhodocollybia maculata (but still without reddish spots).

Summary: True

It would be normal for O. radicata, which is typically associated with redwoods. There were no redwoods within 30 miles that I know of (although one of my neighbors does have one in his back yard). Nor is this a snowbank mushroom. Nor was it found in the spring. So, everything considered, I don’t think Oudmansiella is probably out. At least the species found in Mushrooms Demystified.

I think I’ll have to take a collection the next time I get up there, if I can even find it again. Maybe it’s a Phaeocollybia with white gills (as if).

Summary: Long rooting stipe…

…is normal for O. radicata
