British Plant Galls - Identification of galls on plants and fungi
This guide replaces the earlier (1986) work by Fred Stubbs, and my, how it's grown!
The last section is by far the largest and covers all known British species. (If you have no idea of the gall causer, you'll have to look it up in each section, but this will rarely be the case.) Some of the other sections are less complete.
Each section is arranged alphabetically by host genus. A few plant families (Apiaceae, Brassicaceae, Poaceae) are not subdivided in some sections, but when this is the case, the relevant genera are cross-referenced. Fungi are similarly undivided and only their insect galls are included.
For each genus/family there is a dichotomous key to the galls affecting that host. Sometimes this is subdivided into several keys depending on the part of the host that is affected. Most of the galls are illustrated with line-drawings, and the standard drawings of the gall-causers are also shown where relevant to identification.
The list of abbreviations is on p482.
