Anthostomella on Juncus stems

Enrique Rubio, 14-04-2015 18:47

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
