Cryptodiscus on fern stem?
Edvin Johannesen, 12-11-2019 14:18

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.

We've had this before, right?


Greetings Peter.

The entire (sub) hymenium is staining bluish-green in Lugol. See photo of this and a few photos of spores and asci in water.

So Peter's idea seems to be good!

So - K. idaei, then?

Thanks to both :)
