Hi! I have a very small Cryptodiscus-like specimen on a fern stem. Ascomata 0.2-0.3 mm in diam. The shown spore measures (in KOH) ca. 45x5 microns. Septate, but hard to see how many septa.
I have not come across a Cryptodiscus on ferns. Am I in the right genus or is this another Ostropales?
Thanks for any hints.
Edvin

Re : Cryptodiscus on fern stem?
Hmm,this needs at least a phot of an ascus and a test in Lugol: in Cryptodiscus and Karstenia the entire hymenium gets colorated.

A couple of shots using phase contrast.

So Peter's idea seems to be good!
