| Date: | 19 April 2007 |
| OS grid ref: | SU67 |
| Lat/Lon: | 51° 30' N, 1° 10' W |
| Location: | Vice County: Berks, VC22, England |
| Record Summary: | galled Sallow branches and trunk |
| Associated organism: | on live, galled branch of Salix caprea |
| Identification Notes: | Galls on small branches, cankers on major ones. An old gall, found on a fallen twig next to the Phytoplasma gall that is so common on Salix. Dry-corky texture, with internal tunnels. Similar tunnel running down the centre of twig which connected with the scar around the galls and probably both galls - possibly an old Saperda populnea stem mine. Need to revisit and collect some fresh material. |
