“Christ redeemed us from the curse of the law by becoming a curse for us—for it is written, ' Cursed is everyone who is hanged on a tree...
(Gal 3:13)
In the Ascension of Isaiah, Jesus is hanged on a tree.
Traces of the "tree" are obviously also in Acts, and particularly when Peter is addressing the Jews.
The God of our ancestors raised up Jesus, whom you had murdered by hanging him on a tree
(Acts 5:30)
Fortunately, we know both the answer of the Jews against that accusation:
"On the eve of the Passover Yeshu (Jesus) was hanged. For forty days before the execution took place, a herald went forth and cried, "He is going forth to be stoned because he practiced sorcery and enticed Israel to apostasy. Anyone who can say anything in his favor, let him come forward and plead on his behalf." But since nothing was brought forward in his favor he was hanged on the eve of the Passover!-- Ulla retorted, "Do you suppose that he one for whom a defense could be made? Was he not a mesith [enticer], concerning whom Scripture says, Neither shalt thou spare, neither shalt thou conceal him? With Yeshu, however, it was different, for he was connected with royalty [or well-connected]."

The Talmudist said more than this: he said that Jesus was hanged in the total absence of witnesses! So accordingly he wasn't "one for whom a defense could be made". His death was not visible in this world. Jeschu's death was hidden, since it "was connected with royalty" (it was divine will).
The Christian counter-reaction was the following:
"You Jews are seriously mistaken. Who was hanged on the tree was Judas the betrayer of the our Jesus. And no people could witness his death, since Judas hanged himself".
So yes, in the Talmud there is a mythicist anti-Christian accusation.
