Hi all,
Someone gave me this fungus found on Sarothamnus scoparius.
Black perithecia globulose, 350 high x 300  wide, with a distinct short ostiole,immersed and tearing periderm.

Hamathecium composed of paraphyses, hyaline, septate, 2 µm wide, and cylindrical and bitunicate asci.
Ascospores brown, 1-septate, surrounded by a hyaline sheath, verruculose,  generally asymetrical, 22,5-25 x 10-12 µm.
These precedent features are according to Didymosphaerella spartii.
BUT :
We can see hyaline rounded apical ends on the ascospores (=pore ?). I never read in litterature that this king of fungus has this feature. And I don't believe that Petrak, Chlebicki, Fabre (it comes from Vaucluse, his area of prospection) and other mycologists never see it.


What do you think  ?
 Do I search in another direction (Microthelia complex for example) ?
