asco sur Carpinus

Bonsoir.

Je cherche l'inspiration avec cette espèce trouvée sur Carpinus décortiqué au sol.

Asques issus de crochets mesurant 40-50x4-5um  IKI-

Spores 4,6-5,4x1,3-2um  Q=2,6-4 et N=15

Paraphyses cylindriques mesurant 49-53x1,5-2,3um

Avez-vous une idée pour démarrer ?

Merci d'avance.

Re : asco sur Carpinus
I consider this impossible to determine without vital characters and a section of the excipulum. Could be a  Mollisia or Pyrenopeziza. The asci are really IKI-? M. caespiticia perhaps, which is more probably a Pyrenopeziza?

Re : asco sur Carpinus
Merci Zotto.

Après vérification, les asques sont bien IKI+ (Mon Lugol était défectueux).

L'excipullum est de type globulosa, avec des cellules brunes (pigment intracellulaire brun) devenant hyalines vers la marge de l'apothécie.

Je ne sais pas si ce sera suffisant pour aller plus loin.

Mais merci quand même.

Re : asco sur Carpinus
So the round cells of the excipulum seem to me to belong to a banal Mollisia.

Re : asco sur Carpinus
For Mollisia (not "banal" to me...), I have just A. Gminder's key. Is there a newer/updated key?

With just these data, I don't find a specie that could suit.

Re : asco sur Carpinus
There is no newer key, and yes, the spores are a bit small indeed. Bot you need, for instance, the KOH reaction (yellow or not).

Re : asco sur Carpinus
Mollisia is extremely difficult, and it could still be a Pyrenopeziza.

Re : asco sur Carpinus
Is anybody has sequenced Mollisia species ? ITS ?

May be I could sequence it if it could help.
Hans-Otto Baral, 02-11-2019 23:32
Hans-Otto Baral
Re : asco sur Carpinus
Ha, surely that would help. But it is a pity if you have studied it only in the dead state. Lots of sequences exist in Mollisia, and they tell that a hundred species exist.
Yannick Mourgues, 02-11-2019 23:34
Yannick Mourgues
Re : asco sur Carpinus
Yes, unfortunately it was dead... Are Mollisia's ITS sequences accessible somewhere ?
Hans-Otto Baral, 02-11-2019 23:35

Re : asco sur Carpinus
Many are not uploaded. But for me it is easy to check, I have an alignment with most of them.
Yannick Mourgues, 02-11-2019 23:39

Re : asco sur Carpinus
Ok, so if I can have the ITS, could I transfert it to you to have your opinion ?

With pleasure.
