Observation 15809: Tephrocybe rancida (Fries) Donk
When: 2008-12-24
Herbarium specimen reported

Notes: Fruiting terrestrially and alone in association with live oak. Pileus is 3cm across, stipe is 4mm and total height is 5.5cm. Spores are white. I’m stumped!

Proposed Names

-13% (2)
Recognized by sight: It reminds a bit of Mycena megaspora, but it should have had a straight and rooting stem, so I won’t propose that. The spores remain to be measured too.

Eye3
Recognized by sight: Compare to observation 18990 and see notes in that observation. The stem of this specimen broke off when I pulled it out of the ground, which might explain the confusingly un-taproot-like structure.

Used references: read comments below. H. ovina or H. subovina look like pretty close matches.

Good call Darvin.

I really doubt C. umbonata. This “black form” doesn’t look anything like the Redwood Rooters I have found. I can’t imagine in my wildest dreams that a “normal” looking C. umbonata would age to look like this.

Roody calls the stalk of H. subovina “compressed.” I also see this on some of the colorful summertime Hygrocybes. I would imagine that H. subovina and H. ovina may be regional DNA-seperable versions of more-or-less the same type of mushroom.

Hygrocybe is a good guess…

and there are some dark forms; the split stalk is also typical of that genus, but subovinus doesn’t occur here.

did the gills feel waxy to the touch?

H. ovinus is the best that I can do w/Arora, but doesn’t really match the photos of the European forms. with a specimen, scope and Agaricales of CA you can prob. do better! or not. I’d go w/Hygrocybe as a genus, for now.

I thought this one might be Hygrocybe subovina. One may find this species documented on p. 179 of Roody’s “Mushrooms of West Virginia…” which is available online.

Yeah, as I said…

…white spore print has me stumped. It was white not pink not light pink but white.

Check spore print…

This one looks rather Leptonia-ish to me, not really Mycena-ish…
