Calycina

In December I found something Calycina-like on hard wood of thin branches of a standing decorticated Juniperus communis. I brought it home but could not find a conclusive name for the specimen. Yesterday I found the twig I brought home in midst melting snow. The apothecia are still fresh looking and the only difference seems to be that many spores are now germinating.

Apothecia sessile, 0.5-2 mm diameter. The spores are 10.4 - 13.1 × 4.0 - 4.8, at times with a central septum. I did not not observe clear croziers on asci. The rest in the photos. Any idea what this could be? Southern Finland.

Re : Calycina

I am unable to give a hint. The upper cell of the paraphyses is not alive on the photo. Verifying absence of croziers would be crucial. The spores look just as in C. citrina.

Re : Calycina

In my mind almost all paraphyses look the same, with small yellowish guttules. In just a couple of cases I observed elongated VBs in the paraphyses. I still have not seen a single clear crozier so I would say it is simple septate.

Re : Calycina

This is good, one clear VB on the left of the pic. I see croziers, there are clearly two septa like a V, of course it depends on the view , then every crozier may look simple-septate.

So I have no other idea than C. citrina, which would be quite unusual in spring.

Re : Calycina

Thank you! I did not know coniferous wood is a possible substrate.

Hans-Otto Baral, 31-03-2021 15:37

Re : Calycina

You are right. I have only one sample on conifer (Picea), but many dozens on angiosperms. And the growth on standing branch is unusual too.
