Peziza sp.
Fedorenko Vassiliy, 01-12-2016 08:13
Fedorenko VassiliyHello to everyone!
I'd like to ask for you help with this Peziza.
I am trying to identify it with keys, but all the time I come to a dead end, the spores is too small.
Fungus grows on a ground in fir forest at an altitude of 1800 m

Apothecia size 12-34 mm. Smell indistinct.
Spores (10.2) 11.4 - 12.7 (13.4) × (7) 7.2 - 8.3 (8.9) µm N = 81 Qe = 1.6

Re : Peziza sp.
Are your sure this is a Peziza? It's not clear if the asci react in iodine solution.
Macroscopically, your fungus reminds me Arpinia luteola var. pallidorosea, but microscopically this doesn't fit... The ascopores are probably ornamented, so you have to use Cotton Blue to show this ornamentation.

Re : Peziza sp.
Thank you, Nicolas.
Here is asci in lugol. And larger photo of apothecia. The outer surface doesn't look like Arpinia. Unfortunately I don't have Cotton blue yet. But I looked the spores in saline and lugol, and didn't see any ornamentation, there is a finely warty only.

Re : Peziza sp.
Well, very strange. Stipitate apothecia arte unusual in Peziza... This colour of hymenium with a yellow outer surface looks like Peziza michelii, but if we cannot see the correct ornamentation it will be difficult to determine this species.
Maybe you can send some specimens to me if you cannot get CB.

Re : Peziza sp.
Got it! I'll get the Cotton Blue, matter of time. And If doubts still remain after this, then I'll try to send you a sample.
Thank you!

Re : Peziza sp.
So, I got the Cotton Blue and looked at the spores several times, but always get this result. It's not clearly visible, but there a weak roughness on spores.
