Pseudallescheria boydii is a species of fungus classified in the Ascomycota.[2] It is associated with some forms of eumycetoma/maduromycosis[3] and is the causative agent of pseudallescheriasis. Typically found in stagnant and polluted water, it has been implicated in the infection of immunocompromised and near-drowned pneumonia patients. Treatment of infections with P. boydii is complicated by resistance to many of the standard antifungal agents normally used to treat infections by filamentous fungi.[4]

Fungal pneumonia caused by this mold was the cause of death in three athletes submerged in the Yarkon River after a bridge collapsed during the 1997 Maccabiah Games.[5]
