Entoloma ?

[watsthat]

Found in October in grass with chalk probably not far below. I thought they might be Entoloma sp. Any comments or help very much appreciated.

I think you are looking at Mycena pura.

hi Pete

the gill colour certainly points to Entoloma; it's a big (and rather difficult) genus and there are several pale-capped species which could occur in calcareous grassland

even after doing the "microscope stuff" on one of these I quite often end up uncertain of a determination

but "Entoloma species" is a good suggestion

In calcareous grassland? It's an interesting shout . . .
without trying to be too micro-ist, another occasion when a quick look at the spores (or in fact a spore-print) would be invaluable

unfortunately as they were found in October asking anyone except David Tennant (in role) to go back and do a spore-print is out of the question . . .

Thanks Mal & Chris

The gills very nearly shout M.pura but the habitat argues against. Most confusing is that Michael Jordan and Roger Phillips disagree on gill attachment but Jordans decurrent tooth is apparent in my pic. Hey ho maybe they will appear next year and maybe I will get a spore print or even a microscope.

Interesting, I was going to say either entoloma or mycena species ... that's because I've come across a couple where I've thought it was one at first glance then it turned out to be the other, but even so couldn't quite get a species name to it that I was confident of being correct .... So glad to see that even to a more expert eye they can at first sight be similar.

Most agree that the gills may be attached with decurrent tooth.

You're not alone! I have more than once been surprised when I looked at a spore print and saw those knobbly spores

and that's why in his monograph(s) on Entoloma Nordeloos distinguishes five types of fruit-body within this large and difficult genus; to quote him:

"-Pleurotoid: resembling a (small) Pleurotus or Crepidotus with lateral, often reduced or absent stipe.

-Omphalioid: resembling an Omphalia (or Clitocybe) with depressed to infundibuliform pileus and decurrent lamellae.

-Collybioid: resembling a Collybia with convex or plano-convex pileus with blunt or slightly depressed centre; lamellae adnate or free

-Mycenoid: resembling a Mycena with conical or campanulate pileus, free or adnate lamellae and relatively long and slender stipe and thin context.

-Tricholomatoid: resembling a Tricholoma with convex, umbonate pileus, free to adnate-emarginate lamellae, and relatively thick stipe, and thick context."

I have emboldened the relevant bit
