Bonjour,je serais heureux d'avoir votre avis sur c
Hi again
I think this fungus found on old Juncus stems is an Anthostomella that forms uni (bi) peritheciate blackish, clypeate, stromata 0.3-0.5 mm broad with an encircled whitish ostiole. Asci long cylindrical. up to 140 x 7, with an wedge-shaped, euamyloid, apical apparatus. Ascospores unicellular, without dwarf hyaline cell, obliquely uniseriate, (16-)20(-23) x (5.2-)5.8(6.7); Q = 3.1-4.2, only light brown, with no gelt sheath and no germ-slit.
I don't find a species that matches well with these characters
Have you some idea?
Thanks again
