Ascomycete on Polystichum proliferum

I am hoping for any advice on the identification of this ascomycete I found growing on the underside of Polystichum proliferum in Victoria, Australia. A specimen is lodged at the National Herbarium of Victoria (MEL). There was no reaction in Melzer's reagent.
Recorded on iNaturalist as: https://www.inaturalist.org/observations/299481745
Looking forward to learning more and thanks in advance for your assistance.
Best regards,
Heather Merrylees

Re : Ascomycete on Polystichum proliferum
Hello, I am quite unsure about the asci and spores. The latter are filiform?
The structure of the conglutinate hairs is also not easy to see. Would be good to have some oil immersion photos. And if you have Lugol, please test the asci herewith for possible hemiamyloidity (or use Melzer to a KOH-pretrated mount).

Re : Ascomycete on Polystichum proliferum
Thanks so much for your swift reply and recommendations Hans-Otto.
I agree the ascospores appear filiform - also septate (3?) and quite pointed at the ends. I've attached some of the illustrations from Spooner's Helotiales of Australasia for comparison that seemed the closest.
I'll get back to the microscope this Friday and will update accordingly. Many thanks!
