Can someone please tell me what this is? It has immersed, ca 100 mym diameter ascomata with somewhat gelatinous walls forming a pore or perhaps sometimes a more elongated opening. In that way it reminds of Cryptomyces, although dark. Peridium of small rounded cells ca 2 mym in diameter. Hamathecium of thin unbranched paraphyses. Asci with a tholus with a central canal.
Ascospores 8 per ascus, thick-walled 3-5 septate, middle cells darker (greyish), 22-25 x 8-10 mym, ends pointed to obtuse.
Non-lichenized, I -. On bark of living Ulmus glabra.

Hi Björn
I suspect a pyreno, but at least Cryptodiscus you can exclude if you used Lugol (should have a hemiamyloid hymenium) and the spores are brownish.
I fear you need oil immersion for showing the details, esp. spores.

Re : Not a Cryptodiscus but a bit like it
Yes, perhaps the percieved gel-likeness is fooling me, i need to figure out pyreno options i suppose. Added a spore picture.
