Diatrype on Betula

Can this fungus be Diatrype undulata? I have collected it on Betula alba branches at 1600 m and I think could be this species but the macro/micro-differences with another Diatrype species as D. decorticata are very small. Off course, I don't know the conidia. Ostioles are conical, split and slightly protruding. Perithecia up to 500 microns long. I see any blue reaction of the apical pore in Mlz., IKI or KOH pret. (Rappaz says that the asci are I (+)!!)What do you think?
Many thanks again

Re : Diatrype on Betula
Dear Enrique,
We had a discussion on this forum, a apart of your answers are inside : http://www.ascofrance.fr/search_forum/16922
My personal opinion is that your fungus is very probably D. undulata. I recognize ondulate (ethymology of undulata) stromate that I regularly observe on Betula. But you are right, teleomorphs are very close.
Very good photos, as usual !

Re : Diatrype on Betula
Cher Alain
J'avais lu la discussion que tu me dites mais les differences entre D. decorticata et undulata restent encore peu claires, au moin san practiquer les cultures.
Connais tu si quand Rappaz appele I(+) il pense a la refringence de l'aparail apicale ou il pense á son amyloidisme?
Merci beaucoup
Enrique
