De Vaucouleurs Atlas Description:

NGC 4536 is a member of the Virgo Cluster having a relatively normal star formation rate (Koopmann and Kenney 2004). The unusual appearance of the galaxy is due to perspective: it has a bar which is highly foreshortened, and the main arms break from near the ends of this bar. The bar is oriented nearly east-west and is partly obscured by high near-side extinction. The inner pseudoring is a weak feature, but it is well enough defined to be recognized in the classification. It is half the diameter of the main arms, which are very bright and fairly open. With the general patchiness, we adopt the classification Sbc. An interesting feature of the dust distribution is the X-shaped pattern just north of the nucleus. The color index map suggests the X is partly or wholly due to dust.
