Observation 7558: Nolanea pseudopapillata
When: 2008-05-14
Herbarium specimen reported

Notes: on ground, always near rotting conifer logs though, always a few together or scattered over relatively small area
ST: up to ~60×10 mm, somewhat tough, flattened, hollow, but brittle in that it snaps readily when bent, brown and at best v faintly striate, conspicuously whitish tomentose at base
CAP: 40-50 mm, convex, distinctly umbonate, umbo persistent dk brown, rest rich brown fading to grayish tan, readily splits radially at maturity, translucent striate maybe 30-50% the way in, margin extends 1-1.5 mm past gills
GILLS: barely attached, lt brown to pinkish, never whitish or grayish, relatively thick or blunt-edged, trama composed of weakly-woven long fusiform hyphae, no cystidia of any type found (I checked several sections from two mushrooms)
SPORE: ~10×8 µm, conspicuously angular, 6-sided but not isodiametric, 9.1 +/- 0.5 × 7.1 +/- 0.3 µm, Q = 1.2 +/- 0.08 (N=20)

Collybioid Nolanea

I’d say it’s more Collybioid (or should that be Gymnopoid?) than Tricholomatoid. Regarding the Entoloma vs. Nolanea question, that way lies madness in my opinion. However, in this case it definitely looks like a Nolanea if you are going to use the genus. I would guess that someone has started to look at these genera using DNA, but I don’t know what they’ve found.

It looks like a gill section to me. And this looks like a Nolanea. It be good to post a section of the top of the stipe for caulocystidia and of the cuticle to check the diameter f the hyphae and whether they have incrustations.

Here’s a link to the key.

Hell, I don’t even know the difference between “Tricholomatoid” and “Collybioid” cap! How am I supposed to be confident of my ID?? :)

P. pseudopapillata is Collybioid with gills that “start white”. It’s right in the few other details the key covers (size, color, basal fuzz, spores, e.g.) but I wasn’t impressed.

For all I know it’s an Entoloma and not even a Nolanea

(Oh yes, that was a gill section, taken vertically if that’s the right terminology: edge of gill is on the left, the part attaching to the body on the right. It was taken at 400x, in water mount, reticle marks are 2.5 µm.)

What are your reservations?

I’m guessing something didn’t quite match hence the ‘Could be’ vote or is it just a matter of unfamiliarity with the species?

Also it would be helpful to know for sure what the section you made is. I’m assume it’s a gill section.
