Mollisia or...

Ismael Wind, 25-03-2021 10:28

These little discs on bare ( no bark) dead branch of oak, quercus robur, still attached to the tree.

In the field i thought of encoelia now i am thinking towards mollisia?
The discs are greenish blue and wet with a white rim.
Spores (7,5) 8,75-10 (12,5) very variabel in size some are beanshaped.
Ascus 62,5-72,5
Paraphyses tend to swell near the top.

Re : Mollisia or...

This is quite surely Mollisia ligni. You should test IKI whether the asci are inamyloid. The margin usually bear septate brown hair-like protrusions.

The species was originaly described as Cenangium ligni because of its encoelioid habit.
