Re : A non-lichenised fungus?
Dear Jennifer,
compare with Stigmatodiscus - see the following freely available publications:
https://doi.org/10.1007/s13225-016-0356-y
https://doi.org/10.1007/s11557-018-1435-0
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5788271/
I do not see any gel sheath surrounding the ascospores in your pics which are diagnostic for Stigmatodiscus - but this may be due to the fact that the ascospores illustrated are very old and dead, and probably also due to the slide preparation/mounting medium.
Concerning spore measurements and shape, this could be Stigmatodiscus oculatus, but one would need more clear pics of the ascomata, a thinner section of the ascomata and more detailed pictures of living ascospores to evaluate the gel sheath and septation.
Best,
Hermann

Re : A non-lichenised fungus?
A belated thanks for your comment. Will check my specimen in line with your suggestion. So sorry to have missed it way back in July. My apologies.
