Possible Hebeloma

[flaxton]

Can anyone help with this. Possibly a Hebeloma but I cannot get it to fit so I am maybe on the wrong track. Found under beech in grass and leaf litter.



Cystidia

Slightly granular spores 7-8 x3.9-4.9


No potato smell and tapering stipe very slightly sticky rivulose cap.

Thanks

Hi Mal

Given the 'root' why not Hebeloma radicosum. Only slightly outside the spore size!

no way is that H. radicosum, that is a much stouter agaric, with a very distinctive ring, plus a very distinctive bitter almond smell; sadly with Hebeloma you really need youngish fruit-bodies as veil characters are very important - these look a bit past it from that point of view

I found H radicosum in the same estate a few years ago and so that was one of my thoughts. The membranous and very long lasting annulus is missing though

You can't expect everything Mal

Hello,

this is no Hebeloma. I would searcht his one in Cortinarius. The cystidia you show I can not recognize as cystidia. One element looks like a somewhat elongate Basidium, the other element I can see are basidia. Hebeloma would have the whole gill edge sterile, so there would be plenty of cystidia and not only a singular. The spores look smooth, but you state that they are not. The ornamentation of Cortinarius (at least of thos which come into choice) is +/- isolated small spines and therefore different of those of Hebeloma.
Which Cortinarius? The tapering stipe leaves only two possiblities: Either it belongs into the section Duracini (of Telamonia), e.g. C. duracinus etc. etc. or it belongs in section Vibratilis (of Myxacium), eg. C. ochroleucus etc.

Therefore more information would be required concerning the soil (calcareous, acid) and the host (really only Fagus in the next 30 metres distance?) and the taste (bitter?).

best regards,
Andreas

C. elatior?

[mollisia]

Hello,

good idea, but I don't think so. The wrinkled cap suggest it, but the rest doesn't. C. elatior has usually striate stipe apex and a straight stipe. I have never seen this species with such a thin and espially bent stipe. But it could be a close related species. So I have to extend the possible sections to sections Defibulati and Colliniti of subgenus Myxacium. In this case the spores should be quite distinct rough, more then in the other two suggested sections. But we would need to see that in a preparation in KOH (2-5%) and with a well ajusted condensor.

best regards,
Andreas

Thanks for the effort. I will try and get a better view of the spores. If not the "unknown" folder gets another entry.
