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