Hello! I found these immersed perithecia on a stic
Hello all,
This Mollisia gives me no peace.
I had it for sure as Mollisa_olivaceocinerea (nodosa).
What do you think?
Found on 26.03.2023 on debarked branch of Populus_tremula.
Spores [95% - 18 - QPr - v - H2O(nat) ] = 8 - 9,3 - 10,6 x 2,5 - 3 - 3,6 µm
OCI 1 to 2 with several droplets at the spore pole.
What bothers me is that on an apothecium, the spore dimensions are clearly smaller
and there are also fewer droplets OCI 0.5 to 1
Spores [95% - 11 - QPr - v - H2O(nat) ] = 5.2 - 6.6 - 8 x 1.7 - 2.5 - 3.3 µm
Possibly not properly mature?
Paraphyses KOH-, Asci IKL+ bb, crozier+
Identification attempt with Ingo's prov. key on his homepage and
Hans-Ottos files.
Many thanks for your opinions
Greetings Dirk
first of all, thank you very much for your answer.
Of course you are right and I must confess to my shame that the larger spores are from an Apothecium,
which I worked on later. I had kept the substrate moist during this time, but I would never have thought that another species with almost the same macroscopy could grow on the branch in roughly the same place.
Therefore, I only looked at the spores and then made a key. Rookie mistake!!!
Now I know better.
I am also attaching a macroscopic picture of the second species.
I also have the microscopic characteristics available, but I'd better do it in a separate entry.
You are certainly right about Pyrenopeziza_cf. aquosa. If I look at the prov. key of Ingo, I finally come to P._aquosa, or "Mollisa_calluna", but the spores don't fit.
The micro features fit "aquosa" pretty well.
The asci are approx. 42-48 x 4.5-5.4ym.
The golden yellow exudate was abundant, additionally with crystals? I attach pictures.
Sorry for the long text.
Best regards
Dirk
