Re : Peziza 7105
I'm sorry, I did not notice that you have already written "croziers (-)".
In my humble opinion, the features are more suited to the poorly mature ascomata P. succosa. Did you measure the free spores?
I would suggest check exactly how many drops occurs in mature spores?
Dimensions of spores are more suitable for P. succosa.
In my opinion, the macro features also meet this species.
However, I must admit that often in this group I met collections with intermediate features with which I also had huge problems.

Yes, the measurements are for free spores.

Re : Peziza 7105
In this picture I see the decisive majority of spores with two drops. In my opinion, such a spore content is more suitable for P. succosa.

In spores P. succosella, two drops usually only occur only in immature spores.
