    Je n'ai pas l'habitude de ces minis petits discos alors l'avis des discophiles m'est nécessaire.
Petits discos de 0.5-0.9 mm de diamètre blancs translucides. Asques minis d'environ 25x 5 µm avec des spores filiformes en "L" de 7-10 x 0.5- 1 µm.
Pas très rosâtres pour Hyalinia rosella. est-cela néanmoins ?

Thank you Pimpek, we wait Zotto's opinion.

                Bonjour Jean-Paul,
La récolte vient de :
Bourberain (21), Forêt de Velours "Etoile de la Duchesse", le 7/7/2008 sur Carpinus
Les congressistes de 2005 connaissent cette station.
Abientôt car j'ai cru voir une petite orbilia orange sur un de mes morceaux.
Alain
PS je n'ai en effet pas vu une selue spore atteignant le micron de large.

                Hi Alain
I fully confirm Piotr's and Jean-Paul's correct comments. My spore measurements of nine living collections are 7-8.5(-9) x 0.6-0.9 µm. The length refers to in situ values, meaning that the real length of such helicoid spore is distinctly higher, perhaps 9-11 µm. How did you measure the spores, real length or in situ?
Here some help about the synonymy. Although crystallina is the oldest name for the fungus, my combination into Orbilia created a homonym to a Pezizalean fungus, the existence of which I was not aware. Therefore the next oldest epithet crenatomarginata must be used, because combination of crystallina into Orbilia is blocked.
O. rosella s. Boudier is a synonym, but the original concept of Fries (correct is roseola) concerns a fungus without teeth though with a puberulent margin. Possibly Fries had O. rubella or phragmotricha in hand, but this cannot be proved.

                Thank you fot these great explications.
My measures were a mixt between the two methods.
I make other mesures, but not the extrapolate (=real) measures, they give me 7-8.5 x 0.5-0.9 µm.
