I scoped the spores from this observation. Definitely not Agrocybe/Cyclocybe. First impression is the spores conform to an expectation for Galerina marginata; rusty brown in KOH, roughened surfaces, and a small “dugout” region (plage) near the apex seen on several which were favorably aligned, 8-10 × 4.5-6.

Thanks Dave I will gather that and contact you.

Cyclocybe erebia…

has a distinct partial veil before the caps expand. Sometimes it leaves a ring that persists, sometimes not. (My initial comment that accompanies my ID proposal did not make this clear… my bad there.) The mushrooms seen at obs 114601 very likely represent C. erebia; some have a ring, some don’t. (A subtle detail regarding spore morphology as well as habitat leave room for consideration that 114601 may represent some other closely related species of Cyclocybe.)

Galerina marginata has a rusty-brown spore print, not a dull brown print. Although I admit that the picture of the G. marginata print on Mushroom Expert does look like the one seen in this observation (399025). I have no explanation for this; my own prints of G. marginata look different than Michael Kuo’s photo, eg. obs 390878.

Of course, if there is even a remote possibility that a mushroom may be Galerina marginata, then the mushroom should certainly not be consumed. (It’s the reason why I’m chicken to sample any Kuehneromycyes mushrooms.) But, if you examine spores at 400x you should be able to eliminate either C. erebia or G. marginata from consideration, as these types have spores that are quite a bit different from one another. If you still have the spore sample and it’s possible to scrape some onto a piece of wax paper, then if you mail the sample to me I can scope the spores.

On Mushroom Expert, Cyclocybe erebia is found under the name Agrocybe erebia.

Thanks Dave, Show me as the fool. I don’t see your opinion validated.

annulus is not represented well in the post photos but was present as a thin brown ring at discovery.

from using the KUO Key these are Galerina.marginata but have not had time to check closely
