Four cases of respiratory tract intracavitary colonization (fungus ball) due to Scedosporium apiospermum (teleomorph, Pseudallescheria boydii) are reported. The need for a careful search for anneloconidia, in order to establish the etiologic diagnosis in the clinical specimen by microscopy, is emphasized.
