Pseudallescheria boydii is a species of fungus classified under Ascomycota.[1] It is associated with some forms of eumycetoma[2] and maduromycosis.[3] The asexual form of this organism is named Scedosporium apiospermum.[4]

This fungus killed three athletes injured in the 1997 Maccabiah Games when at the opening ceremony a bridge collapsed into the Yarkon River.

Treatment of infections with P. boydii is complicated by resistance to many standard antifungal agents that are usually used for filamentous fungi.[5]
