Recognized by sight: Deliquescing, I made this mistake recently, collected what I thought was going to be a Parasola then noticed it deliquescing when I got home, then I found setulae on the pileipellis.

all individuals are the same species

I checked this spot a couple times and all the photos are of the same species.

If this is Coprinellus, I think it would of been included in the former Coprinus subsection Setulosi rather then subsection Micacei with C. micaceus. http://www.grzyby.pl/...

I am still leaning towards Coprinellus, but Europe-coprinologist has made me somewhat doubtful, I’m not convinced I was wrong yet though. :)

Not deliquescing?

At first glance the 1st and 2nd pictures looked like Coprinellus, but now that I look closely at the second, it’s debatable whether it is deliquescing. It appears to be darkening evenly rather than from the margin up.

And in the last 3 pictures, the stipe looks too thin and fragile for C. micaceus. Are you certain the first two pictures are from the same group? The stipe is thicker on that one.

The setulas be seen with a magnifying glass. In Parasola auricoma are so big they do not need magnifying glass, you can see how a villus concentrically around the pileus apical depression.

I was under the impression that the Parasola species do not deliquesce as this observation is, in my limited experience this has always been the case. Am I mistaken?
Personally, I would like to see if there are setae/setulae on the pileus surface, is there a way macroscopically to tell they are not there?

it is a Parasola, colors general are Parasola auricoma , but not the enlarged photo pileocistidios appreciate that often occur in surrounding central disc. Alternatively Parasola Schroeteri , we can even think Parasola plicatilis var. galericuliformis.

clearly show deliquescing, I can assure you this is not a Parasola with the new information. :)

the last three photos are updated a couple days later. it is breaking down, but i dont think its deliquescing…they look remarkably like the other parasola on MO. I will check them again in a few days, but I am going to not coprinellus. Thanks for the input from both of you though!

my initial thought was coprinellus when i found them but something seemed quite odd/different about them compared to others I’ve seen which is why i photographed and posted them here…
