I was digging through decaying litter of Ceratonia siliqua to find small greyish-beige ascocarps attached to stick, leaves and what looks like the base of a legume. Specimen collected and examined microscopically. They are about 4-5 mm long and diameter anout 1.2 mm. 

Asci 55x65 um long, weakly IKI +ve, opening sometimes with a consticted rim (like a vase) but not sure about this (see images). Base tapering and sinusoidal (croziers?)

Paraphyses 65-85 um long, with slightly swollen and bent apices, numerous.

Spores narrowly ellipsoid  7-8 x 1.5-2.0 um some taking the stain and have two oil bodies at the poles. 

Medullary excipulum subglobular hyphae 12-18um diameter.

I was thiking this is Ciboria, perhaps americana, although this species is reported on decaying fruit and seeds rather on twigs and leaves. Thanks in advance for your suggestions.
