Yellow agaric for ID

cybershot · #1 (**permalink**) 11-04-2009, 02:50 PM

This single pale yellow specimen was found today deep inside a bole hole at the base of a living beech. Is it perhaps a Pholiota species? The gills were actually much paler but stained by the spore colour of this wet muddy specimen, The cap was smooth and slimy in the wet conditions.

Looks like an Agaricus from here. Possibly a battered A. augustus if it were the aforementioned genus. However, it would be out of season and out of habitat, so I may aswell quash my silly suggestion :P

Hallo David,

I would agree with Pholiota spec. Whether aurivella-adiposa or limonella or still some other species is not to clarify without microscope, as far as concerns me at least.
I first thought of Stropharia percevalii, but the gill colour is wrong and also this species is up to now only growing on wood chips.

best regards,
Andreas

With gills that colour and the time of year I would plumb for Agrocybe cylindracae, I know this is white but I have seen brown/yellowish specimens also.

Hi ANdy,

but Agrocybe cylindracea should have a ring and moreover the reddish stem base would be atypical but is very typical for some species of Pholiota (and also Stropharia percevalii).

Andreas

Hi Andreas,

I totally take your point with regard to this possibly being Stropharia percevalii but I must point out that I have come across Agrocybe cylindracea on many occasions, having lost the ring its supposed to have. I still can't see this being a Pholiotasp. of any description. I haven't actually come across Stropharia percevalii as it is a rare species in the UK with only 6 records on the FRDBI. Therefore I would suggest that this collection needs verifying. If you have the collection David could you get it to anyone to who can determine it for you? Probably worth sending to Kew, though I know that they are curently low on mycologists.

That slightly sticky looking cap reminds me of the chunkier hebelomas, e.g. h.radicosum or h.sinapizans

The spore print was 'Rusty Tawney', and a dried specimen is ready for dispatch Andy.

Watch this space!

Cheers

'Rusty Tawney' spore print! this points toward Pholiota which I still don't think it is but if so I will owe Andreas an apology. Thats the problem with picture ID's one can often end up with egg on ones face. Please let me know what the determination is.

Hallo Andy and everybody,

I think we all know that what we are doing here is trying to give fungi a name by seeing only the picture (and some +/- useful additional informations sometimes). So hopefully nobody will expect a 100% certified determination here. But thoughts or guesses about the shown pictures are (also hopefully ....) nevertheless welcome and may aide the owner of the picture. So in my eyes there will never be the pressure to apologize for a discussion and there in all cases will noone end with eggs in the face. It's the discussion in itself what makes those "determination by fotos" valuable!

just my thoughts about that ....

best regards,
Andreas
