Badhamia utricularis?

Hoping you can help identify this slime mould.
Several clusters found on the underside of an oak tree branch (the branch maybe dead). The substrate seems to be a crust fungus (possibly Peniophora genus as I'm pretty sure I've seen Tremella mesenterica on the same tree). The images suggest that the sporangia change from grey to white before they break open.
Sporangia: Approx. 1mm in width, roughly pear-shaped.
Spores: Black, 10.75 - 12.75um; spore wall: approx. 1.25um; covered in tiny spines: 0.50 - 0.85um.
Not hanging as bunches of grapes or on a bracket fungus, but perhaps this is Badhamia utricularis?

Attached are two images (4x EDFs) of sporocarps (approx. 1 x 1.5mm).
It's appears not to be Badhamia utricularis, but it could be a Badhamia species?
