Can somebody provide me with a file of:Rogerson CT
I found this little Peziza on a moss near a water spring. The diameter of the opened cup did not exceed 2 cm. The color of the intern surface of the cup was brown, and the one of the external surface was rather mauve ( as shown on the photos). Primary microscopic observations and measures suggest Peziza pauli or one of its group member species.
Spore measures = (13,59)14,05-14,99-17,04(17,13) x (8,08)8,24-8,6-9,22(9,78).
Direct observation of the spores under the microscope suggest that they have tiny ornamentations, which I wasn't able to show up on the photos. I have to mention that I did not test amyloidity.
My knowledge and experience with ascomyecetes is modest, and I need your help to ID it.
Thank you.
Souhila.
I don't find that taxon in none of the documents I have near me.
In which book or key did yoy find it ?
Michel
I do not know the species, but after the following literature could be it.
For the employment of Pezizales the following books are to be recommended urgently, in nr. 4 is also P. pauli.
Greetings Peter.

I have FMBDS N°3 and 4 near me, and I didn't think to search inside them.
Thank you Peter to have remind me these recent and useful documents.

Thank you Peter Puwert; I dont have the documents you mentionned (I'll be happy if you could send me a PDF copy, because my documentation is poor); I used the references below:

Autre point troublant : la photo montrant la base des asques laisse en partie supposer qu'il pourrait ne pas y avoir de crochet, cas plutôt rare chez les Peziza. Il faudrait cependant voir des asques encore attachés à leur hyphe ascogène pour être certain.
Merci Nicolas Van Vooren; Je voulais bien tester l'amyloidité, mais le Melzer n'est pas disponible hélas, de même pour le bleu coton (j'attends l'arrivage). Pour le crochet au pied des asques, j'ai remarqué d'après mes observations, que leur forme varie. J'attache d'autres photos, en attendant de refaire les observations correctement comme vous le decrivez.
Merci et bon WE à tous.
