I recently found these quite small fruitbodies growing on a fallen, decorticated trunk of a deciduous tree.
Asci 8-spored, IKI-, no croziers. Hymenium turning a purplish color in IKI. Paraphyses filiform, branched.
Spores 4-celled, measuring 16.3 - 18.8 × 3.7 - 4.0 µm, Q = 4.4 - 4.7; avg = 17.3 - 3.8 µm, Qav = 4.5; n = 3.
I presume this belongs to Ostropales, and is probably lichenized -- the green stuff is the thallus?

Re : ?Ostropalean fungus on wood
Great docu! Could you try a section? The excipulum is important, especially near the margin. How small are the apos? The absence of croziers is not clearly seen.

Re : ?Ostropalean fungus on wood
Thanks. The apos are 0.2 - 0.5 mm wide. I tried to do a section a few times, but didn't really succeed. But here are a couple pics of the attempt.

I think It should be Durella atrocyanea. A.

Re : ?Ostropalean fungus on wood
Yes indeed! I saw D. atrocyanea often with numerous small LBs grouped in each cell, but know also cases of spores with a low oil content.

Re : ?Ostropalean fungus on wood
Thanks to Adam as well -- nice to have a name for this! I examined the sample again, and indeed there appear to be croziers after all. So Helotiales, rather than Ostropales.
