Ciboria caucus?

William SlosseGood evening everyone,

On March 4, 2026, I found the following asco growing on old catkins under a solitary Salix caprea in Beernem, Belgium.
I suspect it's Ciboria caucus.
Can this be confirmed based on the following photos?
Spores (free / in water):
(10.1) 10.6 - 12.1 (13) × (6) 6.1 - 6.6 (6.7) µm
Q = (1.6) 1.7 - 2 ; N = 30
Me = 11.2 × 6.3 µm ; Qe = 1.8

Thank you in advance.

Re : Ciboria caucus?
Yes, for sure, the firm apothecia with thick stipe and the large spores fit well.

I would include it in my article. Can you specify the location? Close to the river?

Thx for confirmation, Zotto.
Location details: Beernem, nature reserve De Vaanders. Salix caprea growing on the edge of a deciduous forest.

Regards,William

o.k., that is about 3.5 km SE of Beernem.
