You are right, this looks like psittacina with a lot of red in the cap, sometimes called perplexa by us in Scandinavia – although we do know that H. perplexa is an american species/variety, probably not seen by us at all.

That this is just H. psittacina,
H. perplexa or H. psittacina var perplexa (at least what we are calling that in northeast NA) lacks green tones at all times. It’s also not as red as the European ones.
See http://mushroomobserver.org/name/show_name/15020
Or Renee Lebeuf’s flickr page

H. psittacina usually goes pinkish as it ages at least on the west coast; look at other observations on this site, the ones I find in the east fade to yellow most of the time.

Yeah I have to hand it to you Irene you must be right. There must be some contamination. I found only that one mushroom that day and brought it home. I didn’t have bags so it was rolling around on the seat of my car and probably picked up spores from something else. I searched for a while to find spores on that gill and I too thought they were wrong. Well spotted. I’ll destroy the image

Yeah, I’d say those spores aren’t right.

Those don’t look like Hygrocybe spore there. They look more like Conocybe spores really, or some Pholiota smooth and brown. Is that the wrong photos of spores for the obs. Or are they contaminate spores? Like did you have some brown spored guy in the basket with this Hygrocybe, so it got spores all over it?

Strange spores

If this is a Hygrocybe at all – how did the spores get brown and thick-walled..?

Anyone want the dried specimen to study?

I still have the dried corpse of this pallid perlexa if anyone wants to study it.
Thanks for your insight Irene.
