Bonsoir,
Sur branche morte décortiquée de Rhamnus pumila, le 03/08/2021, en zone subalpine, vers 2300 m d'altitude (col de la colombière, St-Dalmas-le-Selvage).
Ascospores : 11,5-14,5 x 3-4,2
Asques : 60-75 x 4-8 µm, contenant huit spores.
Paraphyses à sommet renflé, large de 4-5,5 µm.
Les spores rappellent un peu O. quaestiformis mais le corps sporal est très différent.
Merci d'avance pour votre aide !

Re : Orbilia subalpine
Hi Andgelo
interesting collection! We tried to identify it but there is no clear solution. It is a member of section Habrostictis without doubt. Very similar is Orbilia mesaverdiana regarding spore size and shape, SBs, and crystalloid SCBs. The paraphyses in your fungus are not so swollen above and tend to be a bit mammiform or moniliform. How large are the apos? In O. mesaverdiana they are 0.2-0.5 mm diam.
Of course it would be a surprize to find this species, which is known from semiarid mountainous regions of N-America, in a humid alpine environment of Europe.

Re : Orbilia subalpine
Merci beaucoup Zotto pour ta réponse.
Les apothécies réhydratées atteignent 0,6 mm de diamètre.
Malheureusement il n'y a que 3 apothécies, j'essaierai peut-être de faire séquencer...
