Looks like Hysterium pulicare, which is very common on oak here.

Peter.
for determination of these "Hysterothecia", spores are the most important feature. There are two common species which mostly grow on bark of various trees: Hysterium angustatum and Hysterium pulicare. The latter one has beautiful bicolorous spores.

I don't know this taxon, Index Fungorum gave the name as legitimate name suggested in Fries as H. acuminatum. You have to check the descriptions provided in the literature.

Hi,
Yes, obviously H. angustatum ; of course ascospores are a good feature but we must be careful because other genus not so far away provide fungi with such ascospores. For example : Hysteropatella prostii or Mytilinidion tortile.
