Leptosphaeriaceae on Asteraceae

A while ago I collected this pyrenomycete which is likely in the family Leptosphaeriaceae on an Asteraceae of some sort (either Jacobaea or Tanacetum) with immersed ascomata within the stem. Ascospores brown, epsilloid, 5 septate constricted in the middle septa, 28.014-36.208×3.581-4.821 uM, avg 32.523×4.10 n=7, Qe=8.03.
After quite a bit of reaserching I suspect it will be in the genus Paraleptosphaeria. The spore size fitsParaleptosphaeria nitschkei, but the 5 septa seem to not be characteristic of the species. Any help in this would be appreciated!
Kind Regards,
Gustaf Fredell
