Omphalina sp fo ID

[cybershot]

At first sight I thought Arrhenia (Nick will know why), then more likely to be Rickenella fibula, but now I'm veering towards a variation of Omphalina galericolor.

Single specimen; Cap 1cm smooth and crenate; stem 2cm; gills much paler than cap; growing on a sandy mound in amongst moss.

Help with a steer towards an ID would be much appreciated



TIA

Lovely specimen David!

I can indeed see why you might have thought Arrhenia (by the way, a revisit to the A. chlorocyanea site is a must next spring). Whatever it is, it's a lovely little thing- I'm starting to look hard in the mosses for rare little Omphalina and Arrhenia, it's an exciting business.

There are a few Omphalina in FOS V.III but I wouldn't have a clue so I wont suggest anything immediately-(I've looked at all of the species that it might be but there's no info on the internet )

I might have to resort to C&D and then get back to you!

Cybershot hasn't mentioned what was around the area in quite large numbers

Some other interesting little finds.



I think
white spindle Clavaria fragilis
yellow spindle Clavulinopsis helvola.

The little cups on a sweet chestnut are more intersting and uncertain.
from bioimages these could be Hymenoscyphus humuli, but i can find
little info on them. Must get the Ellis and Ellis fungi on plants.

Cheers J.P.

Fascinating- what great finds. I'm loving the more obscure side of fungus nowadays. (My God I sound so old when I say that LOL)

I've got a few new species over the past few weeks and they're all coming in the habitat that I love. Short grass and sandy soil. I've even been scouting the county for identical habitat to where we found the Arrhenia chlorocyanea so that when spring comes, I can revisit.

I love anything like Omphalina and Arrhenia- I don't know why, but they majorly fascinate me.

It's curious how people find there main interest in different areas of fungi,
and good to so we get variety on here. Today anyone looking for mushrooms
or boletes or any common stuff would have been sorely dissapointed but by
searching around we found some interesting stuff and for me it was an
excellent foray.

Cheers J.P.

Thanks for your input guys, and Nick has guessed correctly that yesterday (Saturday) we were looking in the same area where he discovered A. Chlorocyanea - Verdigris Navel back in February this year, and where, at the same time, JP discovered Neottiella rutilans. Again yesterday it was JP's sighting of this latter species, this time in greater abundance and larger size, on sandy soil amongst polytrichum moss which lead me to another possible Omphalina/Arrhenia sp. I note that the the fruiting period for N. rutilans is variously described as autumn/autumn to winter, so it follows that the 2008 finds were, previously in February, the end of one season and, lately yesterday, the start of another.



I totally agree with JP that the lack of species numbers was more than compensated by the unexpected finds and the highlight for me was the discovery of a pasture full of Wax Caps; more especially my first sighting of Hygrocybe psittacina - Parrot Waxcap:



Another great day out at Minley, Hants with JP and Garry (fungi2bwith)

Specimen of Omphalina/Arrhenia sp. sent to ABFG for validation.

Im going along with a possible ID of Cinnamon Navel..Omphalina pyxidata..

It's a very good contender Julie:


"Cap 0.5-2.0 cm broad, convex, becoming convex-depressed to infundibulate; margin incurved, then decurved to plane, sometimes appearing scalloped in age; surface glabrous, striate-sulcate to near the disc, vinaceous-brown, hygrophanous, fading to pinkish-tan, finally pale-tan; context thin, pallid; odor and taste mild.

Gills long decurrent, close to subdistant, pale-pink, fading to pinkish-cream, pallid at maturity; lamelluae up to three-seried.

Stipe 1.0-2.5 cm long, 1-3 mm thick, pliant, more or less equal, straight or bent, hollow in age; surface pruinose, becoming glabrous, colored like the cap, i.e. vinaceous to pinkish-brown, paler in age, often nearly tan; whitish tomentum at base; partial veil absent"

But the lack of striation in my find is puzzling me.

The specimen I sent away for verification has been confirmed as Omphalina pyxidata. Still not sure about Julie's epithet of 'Cinnamon Navel', but it's as good as any other of the Common English Names applied to species, and I like it
