Hi,
A few days ago I found this discomycete on a dead leaf (underside) of Blechnum spicant.
Ascomata: 50 – 200 µm across, ad first white, after three days turning red.
Asci: 35 – 40 x 4 – 5 µm, 8-spored
Spores: 8 – 10 x 1,5 µm
Can this be a Calycina and so yes, which one please?
Regards,
Piet
Photo ascomata: 1a, b and c
- Asci and spores: 2a (water x 400); 2b (water
– x 1000); 3c (IKI x 1000)

Re : Calycina ?
Hello Piet
it is difficult to see whether the apothecia have short hairs or not; have you considered Psilachnum chrysostigmum (with its extensive synonymy! - http://www.speciesfungorum.org/Names/SynSpecies.asp?RecordID=321894)?; it has a variety versicolor which turns red (usually on Phyllitis, but perhaps not impossible on other fern hosts).
