Calycina-like on bark of Pseudotsuga
Enrique Rubio, 10-02-2021 20:52
Enrique RubioOn Pseudotsuga bark colonised by abundant lichens and liverworts.
These small caespitose, sessile, pulvinate apothecia are bluish-grey when young but turn ochraceous at maturity. The margins are very hairy and the spores (very few free) are fusiform and usually with three septa at maturity even inside the asci.
I think in a Calycina-like fungus.
Could you help me?

Re : Calycina-like on bark of Pseudotsuga
There is much light brown globulosa, could it be something related to "Mollisia" ramealis? A Cenangiaceae then?

Hi Zotto
Thanks again!
Surely is not ramealis, but Cenangiaceae does not seem a bad proposal.

Re : Calycina-like on bark of Pseudotsuga
Only a fools question: paraphyses with vacuolar bodies, excipulum a brown globulosa, porus of IKI-type: this I would have determined a Mollisia. Why can`t it be one?
Best regards, Lothar

Re : Calycina-like on bark of Pseudotsuga
Good idea Lothar! On woody substrates I do not know such large-spored Mollisias, except M. ramealis which turned out to be misplaced (correct is Cenangiaceae).

Re : Calycina-like on bark of Pseudotsuga
Hi Lothar.
However, the fungus was not at a proper stage of maturation and I do not even have a proper idea about the morphology and dimensions of the spores.

Re : Calycina-like on bark of Pseudotsuga
From your two photos of living asci I am absolutely sure that the spores are normally septate already within the living asci.

Re : Calycina-like on bark of Pseudotsuga
Hi Enrique and Zotto,
"Mollisia" ramealis I also know - it is already very different macroscopically.
Best regards, Lothar

Re : Calycina-like on bark of Pseudotsuga
Hi Zotto and Lothar
I am also sure that they are septate inside the asci and that their morphology is fusoid, but seeing hardly any free spores is always very uncertain. I will try to study it at a better time.
Thanks to both of you.

Re : Calycina-like on bark of Pseudotsuga
The asci look well-developed. Some species or genera do not easily eject their spores, one must be patient with the water mount.

Re : Calycina-like on bark of Pseudotsuga
When I was studying it, I already saw that it was not at its best. The asci with very few spores and the whole looking rather unappetising for study.
I think it would be better to wait for the spring to come closer and there might be material in better conditions. I'll keep you informed

Re : Calycina-like on bark of Pseudotsuga
New collections of this fungus show many free ascospores (1-)3-septate with a gel sheath after discharge and a new study of the excipulum show a clearly textura globuloso-angularis.
So, I think, as Lothar suggested, it is very close to the genus Mollisia. The mature apos reddening.

Re : Calycina-like on bark of Pseudotsuga
Now I think you should look in Calycellina, folder betulina, and search for Chalara around the apos. - No, I must revise this, the globulosa contradicts it. C. betulina has  at. oblita.  - No idea.

Re : Calycina-like on bark of Pseudotsuga
You don't think it might be close to Mollisia? The spores are certainly not typical of this genus.

Re : Calycina-like on bark of Pseudotsuga
It is a possibility, but sometimes the similarities are only superficial adaptations. See "Mollisia" ramealis.

Re : Calycina-like on bark of Pseudotsuga
Yes. You're right.
