Coccidioides immitis is a pathogenic fungus that resides in the soil in certain parts of the southwestern United States, northern Mexico, and a few other areas in the Western Hemisphere.
It, along with its relative Coccidioides posadasii, can cause a disease called coccidioidomycosis, and it is a rare cause of meningitis, mostly in immunocompromised persons.

 The IEQ Review: Under the Scope
Coccidioidomycosis, the disease caused by a pathogenic fungus called Coccidioides immitis, is also known as Valley Fever because the organism is prevalent in the San Joaquin Valley of Central California.
Coccidioides immitis is a primary fungal pathogen can be isolated from microbially depauperate soils of hot, semi-arid regions.
immitis demonstrates different morphologies in its saprobic and parasitic phases, but is distinguished from other fungal pathogens by the unique morphogenetic features of its growth in host tissue.

 Final Diagnosis -- Case 211
The first coccidial skin test utilizing extracts from Coccidioides cultures was developed in 1927, and would later provide the basis for establishing the epidemiologic characteristics of this disease.
Coccidioides will grow on a number of mycologic media, with mold phase growth usually within 3-5 days at 25-37 C on Sabouraud dextrose agar.
However, a recent 1999 review of Coccidioidomycosis by Dr. Galgiani cites that 46% of Coccidioides cases detected in the HIV/AIDS population occurred outside of endemic areas, suggesting it is currently a disease of "emerging" national/international importance due to emigration patterns and the ease of travel.
