  We study the angular dependence of the dissipation in the superconducting
state of FeSe and Fe(Se$_\text{1-x}$Te$_\text{x}$) through electrical transport
measurements, using crystalline intergrown materials. We reveal the key role of
the inclusions of the non superconducting magnetic phase
Fe$_\text{1-y}$(Se$_\text{1-x}$Te$_\text{x}$), growing into the
Fe(Se$_\text{1-x}$Te$_\text{x}$) pure $\beta$-phase, in the development of a
correlated defect structure. The matching of both atomic structures defines the
growth habit of the crystalline material as well as the correlated planar
defects orientation.
