unitunicate pyreno on herbaceous stem in wet situation, possibly Filipendula ulmaria - S- Sweden

Tiny immersed pyrenomyces appearing as black specks on surface of stem; tiny (!) frb below. Non beaked. Asci non-loosening, in gelatinous, dissolving hamathecium. Ascus apical apparatus very prominent, base drawn into thin stipe, ca. 50-60 x 8 µm. Spores hyaline, slightly falcate-fusiform, with two large drops making them appear pseudoseptate, 22-30(-35) x 2-2.8(3) µm. without appendages or gel.
Suggestions more than welcome. :-)

Re : unitunicate pyreno on herbaceous stem in wet situation, possibly Filipendula ulmaria - S- Sweden
Hi Thomas,
Alas, I don't have a solution to your problem, but I think I collected this species just a couple of weeks later on a Typha leaf (in a place where the plants you mention also grow abundantly).....
Coll: 9th July 2017, River Mole, Gatwick, UK
All my data is identical to yours but the ascospores in my collection were 23-27 x 3.1-4.3 µm and were multiguttulate (but I guess your ascospores are dead which would explain the coalesced droplets and shorter width measurement?)
Sadly I used my specimen up trying to section it (it was too small for my clumsy fingrers!), but if you get any clues I'd be really interested to hear them.
Cheers,
Nick
