It is possible that the white fluff is actually of arthropod origin. There are some types of aphids and scale insects that can produce a coating of wax that looks somewhat fuzzy. That being said, I am not sure about this either. Just wanted to add that to give a bit more thought to this. :-)
Its some sort of fungus
The plant is "wild Lilac", one of the ceanothus species but I don't know what the white stuff is.
