Notes: Found with many many others of the same, scattered all around my suburban yard. Caps mostly brown with some being tan and a select few almost yellow. Most had a redish circular difference in the middle of the cap. Stipe sometimes same color as cap and much lighter in some and some two tone feauturing both colors. Mostly though, stipes were lighter on the top of and darkening as it progresses downward. Spore prints are Brown.

This is Panaeolina, although I can’t be sure every specimen in image 337786 is…
Sometimes the line between brown and black can be subtle, I think its easiest to tell what color it is when printed on foil.
Dave, I’m not sure there is even enough information to know which is more likely to turn up, in my area it seems to be the species that corresponds with the P. castaneifolia description. I think many mycologists are so eager to apply names, especially for well known species we end up with field guides that have pictures of Psathyrella atrospora under the name P. gracilis, when a few minutes of microscopy at 400x could of proven that wrong… I personally think MO could benefit from not being like this.
Dave, thanks again for the advice and it clearly appears to be a brown sporeprint thats been dropped onto the black background. I’ve uploaded two images onto this observation.
on this particular use of the word “rare.” Amongst the hundreds of these LBMs that I run across, looking for a “rare” species seems like a “needle in a haystack” activity… as opposed to keeping an eye out for something that’s perhaps likely to turn up.
for Panaeolina foenisecii. The name Panaeolus foenisecii has also been applied to this type. Panaeolina foenisecii is the currently accepted name, and when you made your post of this obs MO probably prompted you to choose the name “Panaeolina foenisecii.”
P. foenisecii has a very dark print, but not quite jet black… little bit of brown tint. A similar-looking mushroom that has a jet black print is likely to represent a species of Panaeolus. Panaeolus cinctulus can look a lot like Panaeolina foenisecii, but with jet black print.
To make matters a bit more confusing, there’s a species Panaeolina castaneifolia that is similar to P. foenisecii. I have not ever IDed this type. It’s listed as a rare species which has a thicker stipe than P. foenisecii. I assume the spore print color is similarly dark, but not quite black.
Actually, I initially thought this mushrooom to be a Psathyrella foenisecii but must have clicked the wrong name when setting up the observation, which should feauture a spore print of brown or dark-purple brown (so I am told). So if the print turns out to be a jet black should I “assume” it to be a Panaeolina foenisecii with my limited tools?
Dave, I was able to get some thick prints but they all happened to be on white paper…but, just like yourself I have been finding them in large quanities so I will gather some now and drop a spore on black paper. I will snap a pic in a bit. Thanks for the good point!
Also, the habitat and timing are correct for this species. I’m currently seeing lots of P. foenisecii on my lawn.
Goatshoes, did you get a nice thick spore print? You mentioned the print being brown. With dark-spored mushrooms I usually like to view the print against a black background. A black print will almost disappear, and one that has a brown or purple tint will show the color as a contrast to the black background.
A thin dark print taken on white background may be somewhat color deceptive. The print seen in the photo looks black to me, which would point toward Panaeolus.
