vernal Peziza aff. moseri/pauli not fully ripe
Lothar Krieglsteiner, 07-01-2021 14:18
Lothar Krieglsteinerfound 11.3.2020, Germany, Baden-Wuerttemberg, Gschwend, "Bergsee", on soil in a small canyon on calcareous soil (near a lying trunk).
Unfortunately, the specimen was not fully ripe. The season of fruiting is strange, so perhaps there is a hint for me?
(Unripe) spores about 14-16/8,5-10 µm
Best regards, Lothar

I put the specimen in the refrigerator, and about 2 weeks later I tried again - with still only very slightly developed spore ornament, nearly smooth, finely punctate p.p.

Reminds me of Peziza celtica, paraphyses swollen tips similiar. No expert.

Hello Tony,
thank you very much for your suggestion. We will see if there are other opinions - or same ones.

Re : vernal Peziza aff. moseri/pauli pas complètement mûr
Hallo Lothar, ich bin kein Spezialist, aber ich denke, wenn du eine Gelatineschicht auf kalkhaltigem Boden mit diesem Mikrofon und dem Medulla-Excipilum mit globulärer Textur hast, warum nicht zu Peziza exogelatinosa ?

Re : vernal Peziza aff. moseri/pauli not fully ripe
Hello Eric,
thank you very much - this seems to be a good hint, at least near to the solution.
Unfortunately I do not have this:
Hansen, Sandal & Dissing, Nordic Jl Bot. 18(5): 612 (1998)
Best regards, Lothar
P.S. But even if it is exogelatinosa and the case is solved - there remains the fact that it grew in spring, not very typical for "normal" ectomycorhizal fungi (what it likely should be ..?).

Hi Lothar
Do you mean "New and rare species of Pezizales from calcareous woodlands in Denmark"?
Can I send to priva if you want?

Re : vernal Peziza aff. moseri/pauli not fully ripe
thanks, Mirek - yes, I received, and took a first quick look. As it seems, exogelatinosa is a good hint, but no vernal data are given.

Re : vernal Peziza aff. moseri/pauli not fully ripe
Daleomyces exogelatinosus is an option but without correct microscopical data, it is hazardeous to conclude. Or try to obtain rDNA sequence.
Lothar Krieglsteiner, 09-01-2021 12:55
Lothar Krieglsteiner
Re : vernal Peziza aff. moseri/pauli not fully ripe
thanks, Nicolas, for your opinion.
Yes, it should be found again, better ripe - or sequenced. For the meantime I name it cf. exogalatinosa(us)
Best regards, Lothar

Re : vernal Peziza aff. moseri/pauli not fully ripe
Lothar, why do you keep your collection in the fridge if you want it to mature? Peziza at home, at moderate temperature, ripens very nicely and quickly if it is provided with adequate humidity. I keep them in the basement, in a special ripening room, located on the window.
It seems to me that the temperature in the refrigerator is too low and there is no light, which is not good. I put it in the fridge only when I don't have time for microscopy and I want the fruiting bodies not to overripe.
Greetings.
Mirek

Hello Mirek,
you are surely right - it was wrong to handle the specimen this way. Next time ...

Re : vernal Peziza aff. moseri/pauli not fully ripe
Hi Nicolas
The discussion in this forum made me reflect. I do not know P. exogelatinosa by nature, so this species is very difficult for me to identify.
I once asked you about my collection which I called P. pauli but you decided that it is not this species.
While researching this collection, I did not pay attention to the gelatinous layer on the ectal ex. I thought that I did not make the preparation accurately and that is why the view is so blurry. However, several times I made the preparation with the same effect, having the impression that some gel covering the fruiting body was disturbing my observation, so I even tried to rinse the preparation several times. Still ectal ex, she was barely visible.
Then don't you think this collection could be P. exogelatinosa ??
The only thing I don't like are the spores. For me, their length was slightly shorter than what Hansen says. The second measurement taken was slightly different:
Me = 15.4 × 9.6 µm; Qe = 1.6

15.70 9.32
14.93 9.69
15.55 9.50
15.26 10.36
15.37 10.14
16.43 9.88
15.52 9.13
15.56 9.81
14.72 9.09
15.22 8.87
Perhaps they were not well matured?
I am posting a link to my website again and a few more pictures of ectal ex.


greetings
Mirek

Re : vernal Peziza aff. moseri/pauli not fully ripe
Why not Myrek, although your spores are a bit short. On my own collections, they measure 15–18 × 8–9.5 (–10) µm, Me = 16.5 × 8.9 µm. To my experience, the gelatinous layer is thin, about 30-50 µm wide, and so may be easily overlooked. This species grows in fresh or wet habitats, on calcareous soil.
Mirek Gryc, 09-01-2021 18:10
Re : vernal Peziza aff. moseri/pauli not fully ripe
In this case, the layer was also quite thin, but it blocked my view of Ectal ex so when rinsing the preparation it widened a bit :)
Habitat would rather fit too?
Ascomata grew on the side of the road, on a gravel bed. Very little humus content. Rainwater collected in this place, so it stayed wet for a long time. They grew together with Ascobolus behnitziensis.

Until I get to know this species better, I will temporarily change her name to Peziza cf. exogelatinosa.
Thank you so much, Nicolas!

Re : vernal Peziza aff. moseri/pauli not fully ripe
Lothar,

if the spores were longer, you should consider Peziza ampelina that is typically vernal and growing around dead wood (mainly Populus).

With your measurements, and when the spores become finely ponctuate, a similar species that I collect sometimes (early in the season, in March but also in winter in warm spots) is Peziza maximovici, at least I arrived there (see https://www.actaforum.actafungorum.org/viewtopic.php?t=7170&p=80730).

Regards

Mario
Lothar Krieglsteiner, 10-01-2021 11:36
Lothar Krieglsteiner
why not P. maximovicii?
Hello Mario,
this is what looks best by now - and I consider it fully. I saw very fine warts on the spores, but it was not possible for me to get in on the fotos satisfactorily. Everything seems to fit, including the vernal growth. But - to cite Nicolas - to be sure it should be sequenced. As I have no possibility to do this (or better let it do) I will have to cope with the "cf"-determination.
It seems to me as if the species of this complex are very close to each other.
Thank you very much for your contribution!
Best regards, Lothar
