Hoping for a spore drop. On ground near lake under pine/oak.

Maybe Lyophyllum? Maybe Tricholoma?

Tough one

If not blackening or with farinaceous or rancid smell/taste – with that kind of spores, I’d guess something in the decastes group. They don’t always grow fasciculate, sometimes solitary (shimeji in particular). But I’m not sure if it’s a blackening one or not..

Thank you everyone for the input.

I returned to the spot where I made the collection, but there were no more mushrooms of this type. Actually, the “one shot deal” quick fruiting seems to support the Lyophyllum proposal.

Looked at a gill edge.

Spreading away from the edge and out into the KOH solution the spores appear to be in the range 4-6 × 3-4.5 with 1 < q < 1.4; broadly elliptical to subglobose with lots of small ones appearing virtually globose. (These are presumably all spores… I haven’t often looked for spores by examining a gill edge). Newly attached photo shows area near mounted gill edge; mushroom beginning to air dry.

Spores appear to be not angular. Adnate/slight decurrent gill attachment a bit unusual for what I’d expect with our local Entolomas (except for E. abortivum).

Odor nil and taste non distinct.

Also, looks like no spores dropped. I’ll see if I can tap a few onto a slide. Also, I’ll put a gill under the scope.

Warm weather the next few days may bring out a few more.

Context pure white. Gill edges blunt (as seen with hand lense), almost squared, with little or no darkening.

is very likely. A difficult group, but some of them have quite different spore size and shape. Taste/smell could be diagnostic too.
