Bonjour Luc!
The disco is easy: it is
Calloria rubicunda Sacc. & Speg. (= Pezizella rozei (Quél.) Sacc., ?= Hyalinia helleboricola Ade)
specific to Helleborus leaves.
my guess was that it belongs in Psilachnum, but in the meantime I am a bit sceptical. If you have kept this sample in your herbarium it would be worth a try to get a sequence. Maybe someone wants to do this.
