Thanks,

Re : Acorn fungus
We had this fungus a few days ago: http://www.ascofrance.fr/search_forum/65321
It is Phaeohelotium geogenum (Cooke) Svrcek & Matheis, but perhaps better placed in Cudoniella.
The type is from near Paris and the type of the synonym Helotium longisporum Schweers from Netherlands.
Typically it grows on remnants of Quercus, preferably acorns.
From your scale I find the spores 30-38 x 5.3-6 µm.
