Diatrypoid fungus on Alnus wood

Hi againHave you some idea about this fungus on Alnus glutinosa wood at the sea level?
Their erumpent stromata are + or – discoid, pulvinate, 3-10 mm in diam. x 1 mm high. Perithecia 2 to many, in diatrypoid configuration, 0.37-0.57 x 0.42-0.62 mm, sphaerical to flask-shaped, with short conical to cylindrical necks 0.25 x 0.15 mm up to 0.15
mm over the stromatal level.
Asci long stipitate, I think IKI negative, 8-spored, pars sporifera 28-42 x 5-7 µm.
Diatrype? Eutypa?
Thanks again

Re : Diatrypoid fungus on Alnus wood
Hola Enrique,
your fungus looks like small corticolous stromata of Eutypa lata, often not typical. If you have smooth, not cruciform ostioles it should be it. The apical apparatus of E. lata turns clearly blue in IKI but it is not apical but subapical, at the bottom of a short cylindrical inamyloid structure that I think I recognise on your pictures.
If it does not match you will have to consider another taxon but I don't see which one.
Cheers,
Jacques

Re : Diatrypoid fungus on Alnus wood
Many thanks again, Jacques
The ostioles are very indiferenciated and not cruciform. It's very difficult for me to apreciate the amiloidity of the subapical apparatus.
Cheers
