Asci: 40 – 45 x 5 µm. J-

Hi Piet,


It's a Bionectriaceae, probably an Hydropisphaera species, perhaps H. arenula.


Let's wait Christian's opinion.

Dear Piet,
I received your specimen, the ascospores are 18.5-20(-21) x 3-3.5 µm, spinulose.
So, it is Ijuhya parilis (H. Sydow) Samuels.
Thank you for this sending.
Regards,
Christian
