This and a Swedish collection share the same characters.
Ascomata seminectrioid with scurfy amber surface and conical ostioles; densely crowded or more scattered on soft rotten wood in ditch in a drained boggy forest area. Spores 16,2-18,5 x 5,3-5,9 µm, 2-celled, with terminal pores, sooty brown, multiguttulate, septum dark, thick; asci 8-spo., sp. uniseriate; apical appa. massive, lugol negative; paraphyses prominent, longer than asci, attenuated tow. the tips.
Some characters point in the direction of Submersisphaeria

Hi Thomas
Did your specimens showed a subiculum or anything like that? Leroy (2015) states that J. saliciluticola lacks a subiculum (or "croûte stromatique basale"). However, the genus description in Barr (1993) states: "Stromatic tissues form a closely adhering crust around erumpent ascomata or beaks of immersed ascomata.". Some years ago I examined a Jobellisia collection with a subiculum. In other features it matched J. saliciluticola well.
Cheers, Eduard
