Hei, These apothecia are apparently growing on de
Host is fallen cones from an unidentified ornamental Picea sp in Ottawa ontario. The specimens grow from inbetween the scales on the cones.
It is a brownish stipitate ascomycete, stipe sometime have darker warts, they grow individually with few individuals per cones. the specimens measure up to 2-3 mm long. and perhaps up to 5-10 mm high in some case.
The ascus measure 75-95*6.5-7.5µ, they are octospored and usually biseriate to some extend. The have a crozier at the base, and react very faintly (if even) to melzer.
The spore are ellipsoid, smooth and measure 7-8*3.5-4.5 (in ascus), no spores where observed outside of the ascus, suggesting a still immature specimen.
Paraphyse are thin non-ramified treads, excipulum is orangeish and is somewhat moniliform in shape.
From the habitat and aspect I am thinking that this fungi might be Ciboria rufofusca, however there are a few difference here in the presence of biseriate ascus and larger spores. However I do not know if this is enough to indicate that this is another species or just unusual observation due to studying an immature specimen.

I am thankfull for any help in the identification/confirmation of this fungi.
Best regards

your asci and spores appear to me definitely to wide. And yes, although C. rufofusca tends to subbiseriate arrangement in the living ascus, I think that it is never such biseriate.
It would be good to have an oil immerison photo of ejected spores with a scale, to make up ones mind about spore size. Also living paraphyses and their contents would be helpful. On your margin photo I can roughly see that the inflated marginal cellls contain VBs.

Released spore dimension are : 7.5-9.0µ*3-5µ.

Did you see the globose ectal excipular cells?
A Moellerodiscus could be an option.
