Ophiognomonia clavigignenti-juglandacearum is a mitosporic fungus that causes the butternut canker, a lethal disease of butternut trees (Juglans cinerea). It is also known to parasitize other members of the genus Juglans on occasion, and very rarely other related trees including hickories.[1][2] The fungus is found throughout North America, occurring on up to 91% of butternut trees, and may be threatening the viability of butternut as a species.
