Cladonia strangulata is a species of fruticose lichen in the family Cladoniaceae.

The type specimen was collected from Hirakimata on the Great Barrier Island, at an elevation between 450 and 580 m, where it was found growing on the soil.

[1] The primary thallus of Cladonia strangulata is squamulose, (scaly) spatulate, and esorediate.

The podetia are narrow, twisted, constricted, more or less cylindrical or flattened, corticate or sparsely sorediate, with perforated axils.
