Macroscopic features:


Substrate: on sheep dung and mud in a damp, infertile meadow (heath and orchid - Dactylorhiza maculata).


FRB: cushionlike without stalk; less than 2.5 mm diameter ; dark orange, on the edge with green algae formation


Microscopic features (all dimensions in water): fresh material in water and in Melzer.


Asci : cylindrical, hyaline, uniseriate, 225 x 17.45 µm, in Melzer amyloid
Spores: hyaline, globose tot broadly ellipsoid, 14,96-17,50 x 12,60-14,64 µm; Q= 1,20; covered with a transparent gel.
Paraphyses : 215 x 5.25 µm, filiform, with Septa and occasionally branched at the base, top clavate to elongated capitate


Place and date: found by Staf Elsermans 25 november 2014 België, De Dongen, Turnhout; Lambert 189456 218787 IFBL B55744


 Thank you very much in advance!

Re : unknown asco on sheep dung
Adio François,

No hairs ? Are you sure ?
Could you see this ?
Photos are in water ?

In fact, I suspect this is not mature...

Re : unknown asco on sheep dung
Dear Beñat,

The preparation was contaminated with algae but I found no hairs.
All photos were taken in water, I add a photo in melzer.

Best regards,

François

Re : unknown asco on sheep dung
Salut François.

Je pense aussi comme Beñat que ton champignon à souffert; il faudrait que tu puisses en trouver d'autres de manière à obtenir au moins des spores mûres.

Michel.

Re : unknown asco on sheep dung
Dear Beñat and Michel,

Thank you both for your interventions, the mushroom might have also suffered from the frost! The next time better luck.

Warm greetings,

François

Re : unknown asco on sheep dung
Hi François
It might be Cheilymenia stercoraria
Cheers,
Raúl

Re : unknown asco on sheep dung
Hello Raúl,

You restored my hope a bit! Indeed, everything looks very similar to the data I found in "base des données":


http://www.ascofrance.com/recolte/3783/pezizomycetes-pezizales-pyronemataceae-cheilymenia-stercoraria


Unfortunately I have no description/key of Cheilymenia stercoraria. Does it have no hairs on the edge? Also the texture of the excipulum has similarities (see photo).
Thanks for your help.


Kind regard,


François

Re : unknown asco on sheep dung
Hello François,

Cheilymenia stercorea has differentiated hairs, long marginal hairs, also stellate lateral hairs, also some superficial ones, which are simple or bifurcate. Under harsh condition and sometimes also when old, the hairs maybe sparse. However you should find at least some there.


Btw have you tried to stain it to check the ornamentation of spores?


Honza


 


EDIT: sorry, my mistake, I wrongly read it.... You were talking about Ch. stercoraria, not stercorea. Ch. stercoraria is hairless with only hair germs. IF you need some paper about it, I can scan it and send to you.

François Bartholomeeusen, 09-12-2014 19:51
Re : unknown asco on sheep dung, perhaps Cheilymenia stercoraria
Dear Honza,

I would be very grateful if you could send me any information about Ch. stercoraria! Thanks in advance.

Kind regards,

François
