Yes, but this doesn't look like C. coronata.

Re : Cyathicula coronata (Bull.) Rehm
Yes, it's another thing. Here is the description:

Spores 19,7-24,7 x 5,8-6,2 µm    Q=3,4-4  N=20

Ascus IKI+ with croziers.

Paraphyses with refractive VBs, oil content red in IKI.

Textura seems to be gelatinosa.

Re : Cyathicula coronata (Bull.) Rehm
Hmm, the VBs are elongated, very impossible for a Cyathicula. Did you photograph the ectal excipulum? Are the apos cartilaginous?

Perhaps it is a Hymenoscyphus. But when neglecting the apical ring this reminds me of Allophylaria macrospora.

What is the substrate? The latter grows on wood.

Re : Cyathicula coronata (Bull.) Rehm
Yes, it's decorticated wood. Perhars Carpinus or Fagus. Impossible to know.

No, I haven"t take picture of ectal excipulum. Too gelatinosus.

Re : Cyathicula coronata (Bull.) Rehm
Yes, that is the case with Allophylaria too - not easy to make a section or squash mount.

If you have more apical rings in IKI we could fix the name.

Fagus and Carpinus are quite easy to distinguish by a cross break.

Yannick Mourgues
Re : Cyathicula coronata (Bull.) Rehm
Yes, it's Carpinus.

I will try to make a new picture tomorrow because now all is dry.

I will tell you.
