Dear forum members,

On April 25 2024, I found one fruiting body under a layer of wet leaves. The long, thin stem lay on mummified leaves of deciduous trees (no attachment nor scleritium found).
Apotheciium: light brown, slightly saucer-shaped then flat (diameter 4 mm), stem 45 mm long and very thin.
Excipulum with textura globulosa and subhymenium light brown coloured;
Asci: cylindrical, 130-150 µm long, 9-11 µm wide, IKI+(blue) with croziers;
Paraphyses of same length sometimes branched;
Spores hyaline, elliptic to ovoid, binucleate with following dimensions
(10.2) 10.7 - 12.3 (13.2) × (4.9) 5.3 - 6.5 (6.9) µm;
Q = (1.6) 1.7 - 2.2 (2.4) ; Me = 11.5 × 5.9 µm ; Qe = 2

Personally, I think of Ciborinia pseudobifrons but the problem is that while collecting from the leaf litter, the correct substrate could not be detected. In the vicinity were Alnus and Salix and probably other deciduous trees.

What do you think?

Best regards,

François
