Scutellinia sp.

This Scutellinia sp. was found a few days ago in a crevice on a standing rotting Populus log by the river. Spores verrucose, 24-27 X 16-18 ìm. Asci 250-330 X 15-26 ìm. Paraphyses 280-340 X 3-5 ìm (tip width: 6-7 ìm). Hairs pointed, 300-480 X 17-23 ìm, with 2-3 roots.
Any help appreciated. Thanks.

Re:Scutellinia sp.
Bonsoir. Hi !
Il faudrait nous en dire plus sur les verrues des spores :
1. isolées ou coalescentes ?
2. dimensions des verrues : largeur/hauteur.
You should tell us more about warts (warts = verrues en anglais ???):
1. alone or linked up ?
2. warts' size : width/height
Cordialement.
Yannick

Re:Scutellinia sp.
Thank you, Yannick, for your answer.
It was very hard for me to try and measure the width and height of the spore warts. I wonder how you do it! In any case, if my observations are correct, it seems that spore width is 1,2-1,7 ìm and height is up to 1,9 ìm. The warts seem to be isolated.
I hope this can lead somewhere.

Re:Scutellinia sp.
For me, it's Scutellinia subhirtella.
We should wait another opinion.
Que pensent les autres membres d'Ascofrance de cela ?
Best regards.

Re:Scutellinia sp.
I am wondering how it could be S. subhirtella with so few information (text or photographies)
Angelos has to take a look at Jean-Louis' file of S. subhirtella http://www.ascofrance.fr/index.php?r=bdd&page=fiche&id=1526
and also my attached photography of S. subhirtella and tell us if spores ornementation looks same or not.

Re:Scutellinia sp.
Yannick and Francois, thank you both for your answers.
I tried looking at the spores again in cotton blue. The only source for spores was my dried and shrunk specimens, and there I could find very few spores and those only in asci. Unfortunately, all I could see was some rather smooth spores, which, I guess, are of no help to anyone. So, I'm afraid we'll have to leave it at that and hope for better luck in the future.

Re:Scutellinia sp.
my attached file was filtered (157ko), so I compress it a little bit more and it is OK now
