Another on Pteridium

These are about 0,2 mm wide.
The spores are about 16-18x2, asci 40-50x5-6 and paraphyses are numerous.

Looks a bit like Stictis, but is it?

Re : Another on Pteridium
Hello folks,

I think, that I got a bit better photo of a good group on the leaves.
New study give the spore size of 12-16x2. I'm not sure of septas in them, there might be sometimes at least one or not. My microscope is near the end of its journey.

I checked Stictis pteridina syn. Mellitiosporium pteridinum and this is surely not that.
