Thermally dimorphic fungus

Fungi can cause a number of infections in humans. Many of these are only superficial infections, such as tinea pedis or athlete’s foot . However, some particularly nasty fungal infections—ones that can spread throughout the whole body—tend to be caused by thermally dimorphic fungi. Thermally dimorphic fungi exist as a yeast form or a mold form, depending on the temperature at which they are growing. Examples associated with pathological infection are Histoplasma capsulatum and Coccidiodes immitis .
