Taphrina wiesneri is a fungal gall causer affecting Prunus species. The upperside of the affected leaves have hollow blisters that may be reddish brown above; their underside bears a layer of microscopical asci that, when fully developed, may give the surface a mealy aspect. Also many-years old witches’ brooms may be formed.
Good photographs required showing upper and lower leaf surfaces.
Where the host Prunus species occur.
Galls may be found when the host species are in leaf.
True status in Britain is difficult to determine due to lack of records.
Status in Leicestershire and Rutland not known.
