Erysiphe takamatsui is a species of powdery mildew in the family Erysiphaceae. It is found across Eurasia, where it affects lotus plants (genus Nelumbo ).

Description

The fungus forms thin, white irregular patches on the leaves of its host. One other species has been reported from Nelumbo : Erysiphe magnifica , from a botanical garden in Germany. ^[1]

History

The fungus was formally described as a new species in 1999 by Nomura based on a specimen collected in 1974 by Susumu Takamatsu. ^[2] Since the first record of this species on Nelumbo nucifera in a lotus pond of Hakusan Shrine, Niigata-shi, Japan, it has spread: first to elsewhere in East Asia ^[3] and then (likely due to the botanical garden trade) to such gardens in multiple countries in Europe.
