Peziza sp?!?
Edit Szilvásy, 23-06-2013 13:50
Edit SzilvásyDear Forum,
Yesterday I have been found this specie on the mossy ground.
They are small, 10-12 mm diametres. Fruitbody is red, an unusually tough and thick. Spores are 13(14) – 7 (8) micros, with 2 drops oils.
With Lugol is J+. I think this specie is a Peziza.

Any idea?


Thank you, best regards
Edit

Re : Peziza sp?!?
This is a Melastiza species, and you must test again the amyloid reaction of the asci, because it cannot be seen a positive reaction in such species.

Re : Peziza sp?!?
Dear Nicolas,
Now I'm learning the Lugol reaction, unfortunately I was wrong.
I'll try again.
Thank you for your suggestions.

Hi there

I would also consider Aleuria aurantia. Try to check if you find marginal hairs (present in Melastiza) or not. And quicker: if you check the asci base it should not have croziers if it is Aleuria aurantia while Melastiza cornubiensis (=chateri) has croziers.

Re : Peziza sp?!?
Hi Raúl and Nicolas,
I made a test again. I could not find marginal hairs.

I read now J. Breitenbach/Champignons de Suisse: „.... Paraphyses á contenu granuleux orangé teinté en vert par l'iode"


I thought this is the J + :-((
I apologize.


After they confirmed the Aleuria aurantia?
Thank you both for your help.

Hi Edit

If you didn´t see the hairs, then ok for Aleuria aurantia, but notice that they are not very much evident, not pointed nor protuding. Here you have a couple of links where you can see the hairs of Melastiza:

Hi Raúl,
Thanks for the links, all the information is useful to me.
Unfortunately, my fungi aren't typical, edges of the snails eaten.
This fungus was a good learning.
Cheers
