Taphrina alni

''Taphrina alni'' is a fungal plant pathogen that causes Alder tongue gall, a chemically induced distortion of female alder catkins (''Alnus glutinosa'').〔Ellis, Hewett A. (2001). ''Cecidology''. Vol.16, No.1. p. 24.〕〔(Clarification of synonyms )〕
''T. alni'' produces a distinctive tongue-like growth which derives mainly from the ovarian tissues of the alder catkin or from the bracteoles. These alder pseudocones may carry several tongue galls, each of which usually appear to come from the same position; those curling down usually come from the bracteoles tissues and those projecting upwards usually come from ovarian tissues.〔Ellis, Hewett A. (2001). ''Cecidology''. Vol.16, No.1. p. 28.〕
== Distribution ==
This gall was rare in the United Kingdom and is absent from many of the published gall keys, although common in Western Europe. It was recorded in Cornwall first in the 1940s,〔 and then in Northumberland, Ayrshire and Skye, mainly since the 1990s. It is becoming quite common throughout the United Kingdom.〔Redfern, Page 223〕〔(Tongue gall on alder )〕〔Ellis, Hewett A. (2001). ''Cecidology''. Vol.16, No.1. p. 30.〕
