Final answer:
Toxoplasmosis is the exception as it is a parasitic disease, not a fungal one. The other diseases mentioned are caused by fungi, with Coccidioidomycosis also known as Valley fever.
Step-by-step explanation:
The fungal diseases listed are all caused by different types of fungi, except for Toxoplasmosis, which is actually caused by a parasitic protozoan known as Toxoplasma gondii. The correct options, Histoplasmosis, Aspergillosis, and Coccidioidomycosis are indeed fungal diseases. Histoplasmosis is associated with bat droppings and can cause respiratory infections when inhaled. Aspergillosis is another fungal disease that can affect the respiratory system. Coccidioidomycosis, also known as Valley fever, is found in the southwestern United States and enters the body through the respiratory system, with symptoms similar to tuberculosis.
