The systemic fungus that grows in soil and is usually related to bird droppings is Histoplasma capsulatum, which causes the respiratory infection known as histoplasmosis. Histoplasma is a dimorphic fungus that can switch between a mycelium form in the environment and a yeast form inside the human body, particularly in the lungs, after inhalation of spores. This condition can lead to symptoms similar to those of tuberculosis, and in severe cases, swelling of the membranes of the brain and spinal cord.
