These tiny (0.4-0.5 mm diam.), whitish, short-stip

Good evening,
On dead leaves of Ammophila I found black immersed perithecia with 8-spored asci of 110x16µ.
Spores were broadly fusiform tapering at one end, with 5 transverse septae, large guttules, 27x8µ.
My first guess was Phaeosphaeria but the spores were too small for P ammophilae.In the
Handbook of Ascomycota of B Wergen it matches quite well with S caudata.
Thanks Patrik,
Following the Index Fungorum the actual genus is Sigarispora or did it change again?
Marc
