What Faure piece is this?

Hi, I have no idea what this piece is, only that it's by Faure. Can someone listen and tell me if they know? I'd appreciate it.

Even though it says impromptu in the filename, I don't think he wrote any impromptus in C-sharp Minor, which what key the piece appears to be in.

 

I will attach all the files in my collection of Faure which are in C# minor. I hope this helps.

 

Thank you! It's the Improvisation in C-sharp Minor from Pieces Breves.
