When I compare the spores…..

These look much more dark than the P. foenesecii when viewed under the scope. These appear dark gray while the others looked brown.

I should have guessed!

Excise one gill, take it to the sink, grab one end of the gill and gently rinse it under slightly warm water.

Too many spores……

@Alan- I remember you mentioning “washing off some spores” when there were too many. Do you have a method for this? These lamellae were COVERED in spores.

I couldn’t see any sulphidia (Although I barely know what I am looking for!)and only one cystidia, rounded with a sort of papilla.

I do not have a photo….

But they were dark gray, as far as I could tell. I have printed Panaeolina foenesecii next to P. cinctulus before, and these were not jet black.

I agree this one seemed odd and appears different than normal, but the print was not black enough.

I also am not very experienced with these genera, and could be wrong.

Did you print this specimen?

If so, do you have a picture of it? You mention other specimens, maybe it could be a mixed collection? These gills look way too black for P. foenisecii, which don’t turn this color even when rotting in my experience.

Spore print was very dark, but not jet black….

I think this one is older than the rest and beginning to rot, perhaps.

They look black, no way that spore print won’t be jet black. Did you try printing it?

Also, it helps to see the whole specimen in the pictures. :)
