Hi All, Recently I found this minute Bryoscyphus

11-06-2025 13:44

Bonjour,J'ai trouvé cette espèce aux alentours d

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-
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.

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

Could you please tell me the collection data? How sure is Corylus?

If I understand well, 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.
Then I'll give you dat collection.
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.
