Hi,maybe someone has an idea regarding this asco/l
My name is Oliver and I am a recent fungi enthusiast from Germany. I am studying fungi as a hobby for about a year now. I started to do fungal microscopy pretty much at the beginnig.
Yesterday, I found this beautiful fungi on gravel at a graveyard in northrhine-westfalia. I saw directly that it would be a Peziza sensu lato. Nonetheless, I was very suprised by the yellowish to greenish, vibrantly coloured milk. I didn't know that there were Pezizaeae which milk.
After keying this specimen I had to decide between P. michelii, P. succosa and P. succosella. With nearly every spore having only one guttule it should be the latter one. If that were true, this would be the first documentation of this species for northrhine-westfelia. If it weren't, it would be interesting too.
Because I am no expert on Pezizaeae or rather on any ascomycet and I don't know anyone, who could help me with this specimen, I thought maybe some of you could help me.
Spores messured: 17-18 x 9-10µm, microscoped in water and Melzer's reagent (I know that Lugol's is the preffered reagent, but I simply mixed them up)
Kind Regards
Oliver
I want to add some pictures of spores in cotton blue and of the paraphysis in water. They seem to be quite pigmented, which would also speak for P. succosella, am I right?
Kind Regards
Oliver
a reliable determination of your find is not possible with these microphotos.
Is there a receipt (Beleg)?
A good time
Ursula
Kind Regards
I sent you an email

I tried to make some more pictures and it is possible to see the ornamentation clearly now. Although the spores are still in their ascis, they have the same ornamentation as the mature ones I saw.
Kind Regards
Oliver
In my opinion, the morphological features and the image of spores fits P. succosella.
However, the identification of Peziza species is based on more data. You should definitely check the character of Excipulum and the basics of ascus (Croziers +/-)

Ursula Kozik (Gelbfieber) very kindly offered me, to look at this fungus personally and she could confirm my diagnosis. She also very kindly allowed me, to show you her pictures made under the microscope. They are really good!
Kind Regards
