I have been considering an ascomycete which seems to be growing in association with a lichen or alga. There is a slimy, green film on the wood, which is decorticated Betula pendula.
In many ways, it seems to fit best with the genus Patellaria (long, multiply septate spores, asci which rupture at the tip, no reaction to lugol and parallel, regularly septate hyphae in the excipulum).
There seem to be inconsistencies as well (olive green hymenium and paraphyses neither branched nor swollen at the tips).
I have attached a photograph of the fruit bodies and a sketch of the microscopy and wonder if anyone has an idea as to what it is.
Thank you,
Peter.

Re : Patellaria or Lecanidion
Hello Gernot,
Thank you for your reply.
I overlooked Durella. It seems that D. connivens can have olive green hymenium as well as grey hymenium.
The green algal sliminess on the host and the 7-septate spores also fit. I was surprised to see that all of the spores with septa had exactly seven.
I think that you are right.
With Best Wishes,
Peter.
