This minute asco was found on Alnus leave last week.
Spores 6 - 8,5 x 1,8 - 2,3, nearly without guttule.
Ascus with crozier, with a purple reaction with IKI.
Paraphyses cylindrical and not protruding.
Outside covered by brown hairs but white at margin. They are completely incrusted. no reaction with KOH.
I thought to a Fuscolachnum, but dit not find any species that matches.
Thank you,
Daniel
... could fit, please compare. I think this species grows on Salix and Populus leaves, but why not Alnus`(?)
Regards from Lothar
I will check that...
Best regards,

It is the only tree I saw there, but not sure.
Here is the only leave I took.
À mon avis Zotto a raison, il doit s'agir d'une foliole de ronce (Rubus). Je ne pense d'ailleurs pas que les feuilles d'aulne sont poilues.
Pour te donner une idée, voici une foliole de ronce (avec sa célèbre mine due à Stigmella aurella)
Amitiés,

In which country did you collect it?
Bernard
So OK for Rubus !
For Cistella deflexa, the spores of my collection are a bit too narrow, and the purple reaction with IKI does not match. ;O(

Fuscolachnum misellum seems to fit quite well. It looks exactly like in Dougoud's paper : Quatre discales récoltées sur feuilles de Rubus fructicosus, en photographies et dessins.
And the collection in the book on the Biodiversity of Somedio is also similar.
It is shown with a purple reaction on the site Asco-Sonneberg.
Best regards,
Daniel
