Peziza celtica? -> P. michelii
Margot en Geert Vullings, 12-10-2023 15:08
This cup fungus found along a sand path in the sand.
diameter 1.5 - 2.5 cm, brown outside with violet shades inside.
Spores 15.9-17.1 x 8.1-9.65 µ
Ascus 280.9-306.47 x 13.33-14.4 µ
Paraphyses 3.9, top 7 µ
IKI reaction WT, we think?
Spores in cotton blue- lactic acid: warts, we don't know the types?
We think Peziza celtica will fit or are there other options?
Thanks in advance, Margot

Re : Peziza celtica?
Hello and good day Margot,

please compare your find with Peziza michelii.

A good time
Ursula

Re : Peziza celtica?
Thank you Ursula.

For P. michelii I miss the yellowish exterior and I see no milk and no yellow discoloration on white paper?

Regards, Margot

Re : Peziza celtica?
Hallo und guten Tag Margot,

Der Sporenschmuck von Peziza celtica ist isoliert warzig.
Die Sporen Ihres Fundes (Foto im BWB) sind nicht einzeln warzig, sondern durch Grate miteinander verbunden.


Eine gute Zeit,
Ursula

Hallo Ursula,
Vielen Dank für die Erklärung, wir finden die Spurenverzierung immer noch sehr schwierig zu beurteilen.
Herzliche Grüße, Margot

Re : Peziza celtica? -> P. michelii
Good evening Margot,

To assess spore ornaments you need experience and a suitable microscope and a good camera.
I am attaching some details of Peziza michelii for comparison.


A good time
Ursula

Re : Peziza celtica? -> P. michelii
Hello
Definitely P. michelli.
This species is quite variable but the features of your collection fit this species. Morphological features are also consistent.
For me, this species is very common.
I have only a few collections on my website but you can compare. Some are very similar to yours.

Re : Peziza celtica? -> P. michelii
Hello, thank you both for helping us.

Ursula: It is lack of experience, we have to gain that.
As far as spores ornamentation is concerned, is there an overview of the different forms and is this different for each genus?

Mirek: It was mainly the lack of milk and yellow color reaction and the interpretation of the spores ornamentation that made us doubt and gave us another species using the key.

But we are convinced.

Kind regards, Margot

Good evening Margot,

This key also shows drawn spore ornaments:

In order to get a brief overview of spore ornaments of the genus Peziza, I am attaching photos of 22 Peziza species.

Ornamentation in combination with the spore size and shape are never the same. There are also the macroscopic features!


A good time
Ursula

Re : Peziza celtica? -> P. michelii
Hello Ursula,
Thanks again for all the information.
What I meant is a coding of trace ornamentation such as with the ascus tops in Melzers/IKI: WTR, WT and W.
Ornamentation occurs in spores: warts, ridges, network, when is it a network, when a ridge, we don't know how to call what we see, what gradations there are.
Kind regards, Margot

Re : Peziza celtica? -> P. michelii
I agree that your collection represents Paragalactinia michelii, a rather common species, easy to determine in young state, sometimes more difficult when the violet colour of hymenium disappear. In Paragalactinia, the amyloid reaction of asci is of WT type.
About the spore ornamentation, no codification exists to describe it because there is a lot of possible combinations. The best thing to do is to describe it.

Re : Peziza celtica? -> P. michelii
Thanks Nicolas, good to know, we will try to master the spore ornamentation and to get a good picture of it, that is not always easy.

Kind regards, Margot
