Psathyrella indeed, perhaps even gracilis

But, as pointed out below, you need good quality photo of all parts. The more, the better. It’s silly to even venture a guess here, but based on intuition this looks like Psathyrella gracilis group. Psathyrella though, not Stropharia.

Yes, photos…

Yes it would be good to get photos of all features, gills and base.

Really though, if you are going to try anything with the little brown jobs here, all that stuff still isn’t going to get you anywhere. For the little brown jobs it is all about microscopic details really. It is good to get microscopic details if you can, so don’t let that stop you, and if we get enough obs with enough details maybe something will start to make more sense with the little brown jobs…

Still getting the hang of what’s needed for an ID. I thought “Gills: Broad Adnate” would imply lamella. The stipe was equal top to bottom. Are you saying I should have photographed these features? I’m getting some new photo gear to do good disection shots soon. I was also planning on adding spore mycroscopy to all my observations this weekend. Thanks for your help.

Need more…

I can only see the top surface of the cap and some of the stipe here… Does this one have gills? Pores? something else? Also what is the shape of the base of the stipe here?
