Just a couple of really tiny (0.3 mm) apothecia on bark of Betula. Spores ca. 25-27 x 10-11 mcr. (measured in KOH) Appearing septate (but only large guttules?). Aseptate in Baral'sche Lösung. Paraphyses filiform. +/- isodiametric cells plus yellow-pigmented thin hyphae in excipulum. Ascus pore IKI+ (deep reddish brown in Baral'sche).
I am thinking Pezicula cinnamomea, but can it be this small and solitary? Any other Pezicula possibility?
All micro photos in KOH (except last, in Baral'sche).
Grateful for opinions.
