Doubts over a Clumber Park species

[FungiJohn]

I had this down in the gallery as Tricholoma portentosum but I now doubt this. Can anyone offer a more suitable candidate please?

The cap reminds me of Megacollybia platyphylla. I see no hyphal strands at the base though.

Megacollybia platyphylla was suggested in the gallery too Leif. Would you expect to see hyphal strands at the base

Don't forget that Tricholoma would have gills that are notched by the stem, unlike the specimens in the photo which are broadly attached at the point of attachment to the stem.

Megacollybia platyphylla would have been my suggestion too. Sometimes you have to dig a little to find the thick white mycelial strands characteristic of this species.

(Easy to confuse at first glance with Pluteus cervinus, until you tip it up and see the gills, which are broad, attached to the stem and white. Pluteus would of course have free gills turning pink from the ripening spores.)

I can't think of any other options.

Many thanks Leif and Ken. I must start digging a little further in future. How I didn't turn one over for a closer gill inspection and photograph is typical of me If it had been something common I would have had it doing cartwheels

I wouldn't disagree with that diagnosis Leif ! The hyphal strands are only usually very obvious in extremely decayed substrate so there is no problem with them apparently having gone astray.

Thanks too Nick

I'd agree with M.platyphylla too, very tough, white hyphal strands attached to the base of the stem will be very conspicuous when the fungus is pulled up.

If the soil is loose, you will see the strands 1-3mm thick can be 2 feet long but tend not to penetrate too deep, preferring to grow just under the surface of the humus layer.

Thanks Neil I'm happy with the ID but was surprised to find that we don't appear to have it in our gallery ... until now that is

Many thanks again everyone
