This maple was kept in an unheated garage over winter and about a month ago I brought it upstairs into an unheated solarium where it grew new leaves and seemed healthy.
Suddenly (possibly after a cold spell)
All its leaves wilted.
All my other maples are okay it's just this one .
It also seems to have developed some black growth near the bottom trunk.
Is there any hope?

It's a twombly's red sentinel

I have no idea why, but your tree is dying. Do a scratch test below and above the green area.

Scratch test: Scratch the bark with your finger nail or something hard. If the tissue under the scratch is green, that part is alive. If the tissue is brown or it won't scratch, its dead.

The area at the bottom that's turning black is the graft and its dying. It could have been caused by cold or it could be something else.
