Re : Help with identification
Is this mature or does it get more opened finally?
Is it on wood?

Yes, on the upper surface of what I think was Fagus.

Re : Help with identification
Sorry, I missed the first part of your question! It does open up more, most definitely, but they do not appear to flatten out, I think that they remain cup-shaped, rather than discoid.

Re : Help with identification
Do you have a microscope? It could be something around Hyphodiscus, but maybe I am wrong. Photos or sketches of the hairs and the hymenial elements would be necessary.

It reminds me Trichopeziza viridula.

Re : Help with identification
Many thanks, Zotto. I will try again with the microscope, with Hyphodiscus in mind, and try to discern both hyphal elements and hairs. I am hoping that the materialwill have ripened a bit. Any charcacters of the hairs on the outside a difficult to see, at least for me. Hyphodiscus?

Re : Help with identification
Thanks, Miguel, I will try and get some more, microscopic, information. Does anyone know where I can start keying it out?

Re : Help with identification
Hi Simon,
I think the right question is, "when can I start keying out?"
You should try a median section with a rasor blade through an apothecium and document its elements in water (asci, spores, paraphyses, hairs). Then add a drop of iodine to the rim of the cover slide and let it soak in to see a possible reaction of the apical apparatus of the asci. After recording of measurements of all the elements mentioned (before adding iodine), then you start keying. Otherwise you will be hampered to answer the questions asked in the keys.
Good luck!
Martin
