White Calycina with Chalara-anamorph
Enrique Rubio, 06-09-2019 18:25
Enrique RubioSmall, white, substipitate or broadly stipitate apothecia erumpent from bark of Quercus robur (soc. Rosellinia corticium). Asci 8-spored, IKI b with apical apparatus of the Calycina-type, arising from croziers. Ascospores usually bicellular but also short ellipsoid and unicellular. Excipulum with highly developed textura oblita. Many Chalara-like conidia attached to the hymenophoral cells.
Have yo some idea for me?
Many thanks again.

Re : White Calycina with Chalara-anamorph
I am sorry I cannot say. Apos look a bit immature. A positive iodine reaction I cannot see.

Re : White Calycina with Chalara-anamorph
As you well know, it is not very easy to study a very mature Calycina in good condition.
Here is an image of the positive IKI reaction.

It is strange, in this very good phoot I see the ring but no colour.

The colour of the weakly positive ring is very pale blue

Re : White Calycina with Chalara-anamorph
Ws this a twig or a thick branch? Lying on the moist ground?

From Mirek Gryc I got the suggestion that this could be related to calycina italica, but I think the large oil drops forbid such identity, also the shorter spores and more refractive VBs in the paraphyses.

Re : White Calycina with Chalara-anamorph
The branch, lying on the moist ground, was 50 mm thick.
But the excipulum has no vesiculous cells and this makes it even further away from italica.

Re : White Calycina with Chalara-anamorph
In fact, I wanted to confirm the identification of the collection I found.
The spores also contained oil drops. There were, of course, far fewer of them. That is why this collection interested me.

However, there are many more differences between our collections, which rather excludes this species.
