These apothecia were found in cracks on a mossy log with algal growth in a frequently flooded area. The underside is pretty dark, as are the rather short stems. The ectal excipulum consists of intertwined brown hyphae with cylindrical algal cells imbedded. The lower side of the excipulum is almost covered in algae. It almost appears that the fungus is lichenized, but I guess that is an illusion.
I am still trying to figure out vital taxonomy/microscopy. The images below are from material which has been dry for months, mounted in water (except for the IKI one, in Lugol). I hypothesize that we see living spores inside (and outside) dead asci, but I'm not sure. The spores measure approx. 5-6 x 15-17.5 micr.  Asci 90-100 x 7.5-10 micr. Spores contain a few large and sereval small guttules. Paraphyses are a bit difficult to interpret clearly - some seem filiform, some thicker and acuminate, some brownish with granular content. I assume they are dead? I have not seen croziers. The ascus pore stains blue in Lugol (no pre-treatment)

I have been thinking Phaeohelotium, but I am not sure how that genus is cureently to be understood. I don't see a distinct layer with rounded cells in the excipulum.

Any suggestions are welcome.  Thanks.
