Leucoscypha sp. or something else?
Nedim Jukic, 18-07-2011 19:43
Nedim JukicHello and greetings from Bosnia & Herzegovina and Sarajevo,
this is my first post to ascofrance, but surely not the last.

I`m curious about the Pezizales illustrated and shown bellow. I found three fruit bodies in the dry but still wet stream bank, accompanied by Trichophaea woolhopeia and Humaria hemisphaerica. Specimens were growing from the wet soil covered with the a little moss (not sure which species), and some kind of gametophyte, apothecia 0,3-0,5 cm in diammeter.
Other micro data are mentioned at the drawing.
Could be this some species of Leucoscypha, by the fusiformes shape of the ascospore it looks like possible solution for me, but I don` have proper literature, works and key for this genus...
Full mature spore dimesions: 24-25x8-8,5

I would be very thankful if someone find solution (I still have one live fruit body in the box, for potential further neccessary analyses).

Also I would appreciate if someone could mail me any litterature about this genus (besides L. semmi-immersa and L. patavina).

Dear Nedim
Please compare with Peziza gerardii (see my card on Ascofrance), The asci of this species have an very irregular reaction in Melzer.

Dear Nedim?
IKI negative is really surprising with these features and I agree Carlos's proposal.
I think that no Leucoscypha is purple and species are clearly hairy.
Maybe you have to try another iodine reagent but I remember having tried several ones (Melzer and Lugol) on Peziza varia without success. Nothing is perfect!
Cheers
François

Dear Enrique,
Thank you very much for your quick response, and very useful hints.

Yes, now I see clearly match after comparing it with your findings.
As you`ve mentioned, although I`ve made a note that reaction with J was negative, I`ve noticed some strange irregulary, barely visible light bluish/or even greenish pigment in the upper part of the asci.

Désolé, j'ai pas pu résister...


Sorry Nedim for this private joke! I agree with my colleagues, it looks like Peziza gerardii.
