Observation 64668: Cortinarius subgenus Telamonia (Fr.) Trog
When: 2011-03-23
No herbarium specimen

Notes: 3-23-11
Rowan Co., NC
USA

Found alone, growing from soil, on the edge of a gravel path, in predominantly hardwood forest.

Pileus:
2.2cm broad, Brown, Convex, Smooth, somewhat Moist

Lamellae:
Adnate, Sub-distant, Tan or Creamy-Brown

Stipe:
2.1cm long, .3cm wide, Brown, Equal, Smooth, somewhat Hollow

Smell:
Fungoid

Spores:
Print:
Yellow-Brown

Shape & Texture:
Ellipsoid (It seems that some exhibit a Plage), Rough

Cystidia:
Pleurocystidia:
Absent

Cheilocystidia:
(?)

Also:
I’m unsure of what I’m viewing in the cap cuticle. There are two photos of the cap cuticle; One that looks like fat elongated cells connected to one another and the other that looks like long filaments.
Could someone tell me what I’m looking at?

Recognized by sight: Growing from soil, tan spore print, underside of the cap / stem just looks like Inocybe. Check the pleurocystidia and cheilocystidia again, both Galerina and Inocybe should have some distinctive ones.

Cap cross section

I added two more pictures from a cross section of the cap.
I don’t know if I did it correctly or not, so please let me know if I’m viewing the wrong thing.

also, I agree on there being no cheilocystidia. I viewed another cross section today and saw no cystidia.

Cap surface…

You really need to be looking at the cap surface in a thin cross section, not just down at the surface like that. The structure of the layers of cells on the surface is what you need to see. But what you see there are just hyphae.

But the spores look fairly warted here, so this isn’t Inocybe. Also the clavate cells on the gill edge look just to be basidia, so there aren’t any cystidia there. That kinda also rules out Inocybe, but without cheilocystidia, that kinda rules out Hebeloma with the lightly warted spores. It kinda looks like this is a Cortinarius, so kinda dried out Telemonia perhaps.

Inocybe…

I didn’t even think about Inocybe because of the smooth cap. But it was growing from soil, so Inocybe is more fitting.

Do some of the spores exhibit a plage?
Some appear that way to me, that is why I suggested Galerina.

I’ll check back into the Pleuro- and Cheilo- cystidia within the next few days.

Also:
Could you (or anyone) tell me what I’m looking at in the two “cap cuticle” photos?
