Blastoschizomyces capitatus (formerly known as Geotrichum capitatum) is commonly found in the environment and may be recovered from healthy humans' skin, gastrointestinal tract, and respiratory tract. The genus is characterized by the production of true hyphae, pseudohyphae, and annelloconidia resembling arthroconidia and the lack of blastoconidia.
Invasive disease can occur in the immunocompromised. Those with hematologic malignancies are at the most risk. Infection with B. capitatus presents similarly to invasive candidiasis in neutropenic patients. Most patients have fungemia, and many develop deep organ involvement.

Under a magnification of 475X, this photomicrograph reveals some of the ultrastructural morphology exhibited by the fungal organism of the genus Geotrichum. A yeast found worldwide in soil, water, air, and sewage, as well as in plants, cereals, and dairy products, Geotrichum spp. may cause opportunistic infections in immunocompromised hosts, which are referred to as Geotrichosis.
