Possible Clitocybe for ID assistance

[RobSutton]

This one is causing me some problems. I think it's a Clitocybe but not with any huge confidence. It was growing on a moss covered limestone rock under beech. Cap was up to 50mm with the stipe 5mm x 30mm. There was no really obvious smell apart a general fungusy one.



Microscopically it had rather long fusiforme spores 9.4-10.3µ x 3.4-4.3µ with a Q of 2.1-2.8. There were no cystidia on either the gill edge or gill face. Basidia were four spored and the hyphae in the pileipellis had very conspicuous clamps.





The only one I could find (in Funga Nordica) with spores to match this was C.inornata but this is supposed to have a smell like linseed oil and conspicuous rhizomes - neither of which I recorded.

Does anyone have any other suggestions? Your help as always is much appreciated.

Hello Rob,

I think there is not much other possibility than Clitocybe inornata. The striking fusiform spores are very diagnostic. The morphology also would suite more or less, though I know that species usually with a ribbed cap margin and more greyish in the gills. But it would still be o.k., the species often looks like a Hebeloma on first glance.

best regards,
Andreas

Thanks Andreas

I did originally think it was a Hebeloma until I got it home and got a spore sample of it. The gills incidently have gone much more grey overnight.

Thanks as ever for your help.

All the best,
