Summary: The $\dagger $-shape tree is the coalescence of the star $K_{1,4}$ and the path $P_{n - 4}$ with respect to two pendent vertices. In this paper, it is showed that the $\dagger $-shape tree is determined by its adjacency spectrum if and only if $n = 2k + 9$ ($k = 0, 1,\dots$). Furthermore, all the cospectral mates of the $\dagger$-shape tree are found when $n = 2k + 9$.
