I found this one on death Arctium sp.

The apothecia are mostly 0,5-1 mm wide . Hairs cylindrical septate 40-60 x 3-5 µm. Paraphyses cylindrical diam. 2-2,5 µm. The asci are 8 spores 40-45 x 5 µm . Ascospores 7-10 x 1,5-2 µm.

Textura globulosa / angularis

Re : Hyalopeziza sp. ?

This is a Pyrenopeziza, but which?

Re : Hyalopeziza sp. ?

Thank you

p.s. Pyrenopeziza aff. arctii ?

Re : Hyalopeziza sp. ?

Certainly not, that species has much longer septate spores.

It reminds me of P. rubi but that should be on Rubus.
