ID please

Lepiota? Hoping for Lepiota konradii...



Hoping for Pseudoclitocybe cyathiformis, but looks more like Cantherella umbonata...



Wild guess...Megacollybia platyphylla?

Sorry about the state of the photographs, still learning how to use new camera...

I'm going to pass on the Macrolepiota because there isn't really enough information in the photos. On a general note, sections of the specimens can be very helpful... but it also helps to have a photo of the entire specimen before you cut it down the middle. Views of the surface of the stem can be important.

Pseudoclitocybe cyathiformis is much more goblet-shaped than the specimens in the second photo, and tends to be quite dark brown in colour. These are one of the small Clitocybe species with decurrent gills and hygrophanous caps (i.e. the caps change colour on drying). Smell and taste can be critical in narrowing down to species, as can the nuances of colour.

Megacollybia platyphylla has a cap that is radially fibrillose and not hygrophanous. (It can look a bit like Pluteus cervinus at first sight, but of course it has white, rather than pink spores, and the deep gills are attached to the stem rather than free.) The thick white rhizoids attached to the base of the stem are a giveaway when you see them. This is not that species. It clearly has a hygrophanous cap. Not having a view of the entire stem is a hindrance to identification but I think this is Collybia butyracea.

Yes, looking in the book I think you're right on the third one...it's a species I ought to know how to ID but never quite managed. The surface is very "buttery" and it was growing in the right place. Thanks.
