02Description

Species Profile

Taphrina ulmi is a species of fungus in the family Taphrinaceae. A plant pathogen, it causes leaf blister galls on elm trees.

Taphrina ulmi faces significant threats from widespread elm decline and habitat loss across its range. The fungal pathogen's vulnerability is closely tied to the health of elm populations, which have been severely impacted by Dutch elm disease and urban development pressures that reduce suitable host tree availability.
