obviously it looks like a white version of a psath, but pink color at apex also obvious here.

but it really doesn’t matter!!!

and I know that pluteus have free gills. like amanitas. which sometimes don’t have free gills. these look narrowly attached. but Irenea already convinced me that pluteus was not possible with those veil remnants. don’t know why other monitors aren’t showing that pinkish color. come on over here and look! a pinkish color doesn’t make it a pluteus, just makes it a curiousity.

Dimitar, you got my point. That’s why I was asking Alan if the white gilled mushroom was growing in the same patch- because it looks like Psathyrella, but is missing enough of the diagnostic features (colour of pileus + lack of obvious veil fragments) to safely assume it is P. longipes or the same species as the other mushrooms pictured. If no microscopy is done, then I would call the other mushrooms observed P. longipes, with the note that the ID is based on macroscopic features alone, thus it could be another species.

My point in checking for pink spores was to see if it could possibly be anything else pink spored. I wasn’t really considering Pluteus, and I certainly suspect this is an under mature Psathyrella.

That said, I checked on the other monitors and still don’t see any obvious or subtle pink to the gills.

Pink or no pink, the gill attachment is not Pluteus.

The white collection is a Psathyrella of some kind. Spare yourselves
further exercises.

My concern here is different — the two collections appear different
enough that it is warranted to be split and treated as different until
inspected closely and proven to be the same. It is very likely that
they are the same, but again, dealing with one form of Psathyrella is
hard enough, but more…

Otherwise the stature of the dark one does look like longipes.

But again, it is stupid to guess Psathyrella without doing at least
part of the diagnostic verification. I just treated one in full on

It’s a fun Genus, but needs love and attention.

I looked there again, but I still don’t see it. Maybe a slight buff colour, but not so much on the gills, but rather between the individual lamelle where you can see through to the cap, and that might just be shadowing. Okay, how about this. I’ll go to the other two computers in the room and see if it is just the monitor, and if there is another computer in your house, maybe David’s or something, see if the colour looks any different to you on a different monitor?

well I can’t actually make out the individual spores, but there is a definite pink coloration…

at the apex and where the gills are close to the stipe. could just be a…pink coloration.

Uhhh, I enlarged both of the gills shots of the pale mushroom and don’t see any traces of pink spores. I can usually see subtle features like that, especially if pointed out, but I don’t see any pink. Instead they look a little bit mottled white in appearance. Maybe the spores haven’t developed yet, or this is an albino.

click on the photo of the white gilled mushroom for enlargement, then click on it again…

it will enlarge two times, and then even your eyes will see the glory of the pinking of the spores! I would not be able to see that subtle feature in the small photo, either.

My eyes aren’t good enough to locate any pink spores

But there could be.. Albinism can be total, or just with a lower concentration of pigments or one component missing. I’m looking forward to see Alan’s micro shots of this one.

ah yes, tiny bits of veil, fair enough, not pluteus then…but what about the pink coloration?

look closely at the apex of the stipe and inner gills, they are pink. or are the normally dark spores in an “albino” form pink??? how curious!

Pluteus with a veil?
By: Irene Andersson (irenea)

Nah, never seen that. This looks like a Psath to me – but sterile or albino.. It would be interesting to know if it has any spores at all.

your white gilled “psath” has pink spores! (enlarge to see)

No, it was growing by itself.

Alan, was that really pale one growing near the rest?? I wonder because not only are the gills really white (especially in consideration of the size of the mushroom), but the pileus is way paler than than the other mushrooms in this observation. There are also no apparent veil fragments on the margin.
