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

Ascus and hairs...

maybe Cistella deflexa
... could fit, please compare. I think this species grows on Salix and Populus leaves, but why not Alnus`(?)

Re : Hairy disco on Alnus leave
Fuscolachnum isn't a bad idea. And you are sure it is Alnus? The hairs remind me of Rubus.

Re : Hairy disco on Alnus leave
It is the only tree I saw there, but not sure.
Here is the only leave I took.

Re : Hairy disco on Alnus leave
Salut Daniel,
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,
Bernard

Re : Hairy disco on Alnus leave
F. misellum varies rather strongly in spore size, depending apparently on the geography (especially more atlantic samples are often smaller-spored, and maybe the longer-spored ones tend to have an apical ring reacting red).
In which country did you collect it?

Re : Hairy disco on Alnus leave
Oui Daniel, je confirme définitivement une foliole de Rubus ! Regarde sur la nervure, on y voit encore des aiguillons typiques de Rubus.

Re : Hairy disco on Alnus leave
Oui, très possible Bernard, il y avait beaucoup de ronces à cet endroit.
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(

Re : Hairy disco on Alnus leave
Thank you Zotto,
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

Yes, Ingo Wagner observed this red (pruple) reaction.
