Pyrenopeziza digitalina? Je ne suis pas sûr

Bonjour,
Cet disco était sur un Digitalis purpurea mort. C'est Pyrenopeziza digitalina? Je ne le pense pas. Mais qu'est-ce que c'est?
We found this little disco on the flower stalks and dead flower remains of Foxglve, Digitalis purpurea. It was with Flagelloscypha (cyphelloid), and the Hymenomycetes Periconia byssoides and Dendryphion comosum. The only similar species of discomycete on Digitalis in the UK seems to be Pyrenopeziza digitalina. However, that species isn't described as having hairs, is reported to be found on dead stems, and looks darker. Pezizella discreta and Pyrenopeziza revincta have also been found on Digitalis, but I don't think I have one of those.
The ascocarps were sessile, fringed, and up to 0.3 mm diameter. Released spores were few but I estimated them to be about 7-10 x 1.5-2. Asci were biseriate, without croziers, and typically 40 x 5. The tips turned blue in Lugol. Some cells looked like hairs, and were minutely spiny.
Cordialement,
Steve

I think this is a Cistella species. The spiny hairs are typical.

No, it is a fungus with a hyaline excipulum, a Cistella sp.

Re : Pyrenopeziza digitalina? Je ne suis pas sûr
Thankyou, Enrique,
That is very helpful.
This has apparently not been recorded on Digitalis (Fungal Records Database of Britain and Ireland),
Kind regards,
Steve

Many thanks Zotto,
I shall look up this genus now!
