Recognized by sight: The scales on the stem, prominent umbo and lack of a veil match the description of A. smithii. Does anyone have experience with that species who might know for sure?

So Danny M. and Alan R. are of different opinions based on simply a picture. I don’t think I can add anything to resolve that unless someone has a macro feature that separates the two ringless Agrocybes.

Not A. praecox.

It doesn’t have a ring and the stem is more clavate than A. praecox.
There is no A. smithii on MO (e.g. a Seattle local no ring variation mentioned in Ammirati, Trudell; Mushrooms of PNW), so I’m going with another no-ring Agrocybe of the right size after a suggestion from my friend Danny.

Other ideas welcome.
