Bonsoir and good evening,

I got some collections of pezizas from a friend for determination. I am not very familiar with this genus since my forest is on acid ground (sandstone) and I do find them rarely. But she lives in a calcareous region (close by) and collects them in abundance.
I stuck up with determination right at the first specimen. I went through different keys (Hohmeyer, Nordic Macromycetes) and stranded allways at P. lividula. Which doesn't fit, at least considering shape of spores beeing not fusiform or subf. at all. My problem with those keys is that my specimen doesn't show any milk/latex. They were harvested only few days ago and kept refrigerated.

So here is what I have:
Apothecia are blackish darkbrown with a distinct purple to violaceous tint, up to 4.5 cm in dm.
Asci are IKI+ and c. 375x15.5 µm in size.
Paraphyses are septated and slightly moniliform (are they?) with a medium width of 6.5 µm, with some
yellow-brownish drops in the slightly clavate apical section.
Asci are ovoid with predominantly one oildrop and covered with an even ornamentation of rounded warts (16.6-18.1 x 9-10.5 µm).
What I have seen of the textura of the excipulum was a globulosa.

I will be happy to hear some suggestions. Maybe it is just a trivial one...

Best regards,

Martin
