Arora says volva absent in Cortinarius pinguis.

But I didn’t notice the gelatinous volva until you pointed it out, Darvin. WTG!

After collecting this species many times, the one thing that strikes me about it is still the odor: it is rank, metallic, sticking to the nose and everything it touches. The odor persists much longer than the sporocarp itself.

While Arora says edibility unknown, I would caution anyone about eating any Cortinarius without a Cortinarius expert in the house, like maybe Helen V. Smith. But the odor of C. pinquis, fortunately, should throw edibility out for most people. Good thing, I think.

The top photo appears to have a gelatinous volva.

The specimen shown in the second photo was an imperfect cross-section. I just tore the pileus open to see the gills (or lack thereof); I’m sure that if I had used my knife to cut it in half carefully it would look like the specimen in the first photo. These two photos were only a couple feet apart.

May be 2 species here.

Thaxterogaster pinquis (now deprecated to Cortinarius, at least for the month) has a stipe continuing through the pileus. The photo of obs. without stipe thru pileus could be Brauniella nancyae, or similar Brauniella.

This feature is something most mycologists will not pursue: who wants to slice Cortinarius (or Brauniella)? Brauniella should have been found on wood, though.
