Description:Under a relatively-low magnification of only 20X, this teased wet mount-prepared specimen revealed some of the ultrastructural details exhibited by a group of cleistothecia from the saprophytic fugal organism, Pseudallescheria boydii, which is also known as Petriellidium boydii, and Allescheria boydii.
A cleistothecium is a closed fungal fruiting body that acts as a container for developing asci, which are the sexual spore-bearing cells produced in fungi from the phylum Ascomycota.

Pseudallescheria boydii, a true fungal organism, is known to be a cause of the disease known as mycetoma, a cutaneous infection, though this organism has also been cultured from infections involving the lungs, cornea, ear, sinuses, and meninges. Immunocompromised individuals are at a greater risk for succumbing to pathologic involvement with this organism.
