ID request for what seems to be a true aquatic fun

ID request: This specimen was collected in Malta o
Bonsoir à tous,La semaine dernière, j'ai trouvé cet asco ressemblant fort à un Peziza sur branche pourrie de noisetier (Corylus avellana).
a) asques octosporés, à spores unisériées, IKI-Â
b) spores elliptiques, remplies complètement de petites gutttules, lisses : 19-24x7-9
n.b. : certaines spores présentent un petit apicule à chaque extrémité (germination de spores secondaires ??)
c) paraphyses filiformes, septées, ramifiées, à contenu réfringent vers l'extrémité
Pas d'idée…

Bernard
could you show us a photo of an ascus tip in IKI? This reminds me of Rutstr. alni from the alps.
Zotto
there are IKI- ascus tips in the third picture.
regards
Martin
I am unable to see that :-(
Zotto
Indeed the asci are IKI- but I will try again by putting more lugol and leaving perhaps a little more time in order to see a possible change at the top of the asci
I doubt even though it is a Rutstroemia because I find that apothecia is not thick towards the base and the stem here is short and not thick like usual in this genus.
See you this evening.
Bernard
I don't know how it's possible today but the asci are IKI+. Here are some pictures.
Diameter apothecia : 1,5 cm maximum
Bernard
Could you  please tell me the collection data? How sure is Corylus?
If I understand well, Â you tell me it's Rutroemia alni ?
Indeed, I dont 'have the description of this species. Is it a rare species ?
I am practically sure that the host is Corylus avellana but I will ask the opinion of others mycologists.Â
Then I'll give you dat collection.Â
Bernard
 You can look at my alni folder. There is also a sample by Patrice from lowland. And Breitenbach's R. firma (153) seems to be alni too, and they say Corylus.
