Can you tell me in an immunodiffusion test to diagnose histoplasmosis, patient's serum is placed in a well in an agar plate?

In brief: Yes, it is

Immunodiffusion is a test where the antigen is placed in the center of the agar plate and the antibodies (Patient's sera that contain antibodies) in wells at the sides of the dish.
The antigen and antibodies diffuse from the wells towards each other; where they meet, there forms a band (precipitate) that can be see. No band - negaative.
