Seems an age ago now, but on Monday went looking for Oak Galls along Digby Avenue in Wollaton Park. Harder to find this year, and no Trigonapsis 😞, but quite a few nice Andricus gemmeus.

Highlight was an Alder Tongue on by return route (a gall I've missed out on locally).

A gall of Andricus gemmeus nestling amongst epicormic shoots of an Oak. The gall is small, 4mm, and consists of a hemisphere of numerous conical projections in shades of yellow and red.
A green Alder cones with black 'tongues' protuding. These are caused by the fungus Taphrina alni which cause the plant tissue to grow in unusual ways.
A brown scruffy growth on the end of a twig. This is an old Artichoke gall.
Three different oak galls on a twig. Left to right: large and small hemispheres are Marbleand Colanut galls, whilst the long horn like ones are Ram's-horn galls.

@fowp Of course you can. The records are all on iNaturalist (with a view older ones: inaturalist.org/observations?n), and I think all the photos are licenced CC-BY-SA on there, including Timaspis. I've even got one or two gall records from the Arbour Oak.

About 9 years ago I had a productive session looking for galls in the Hall Gardens with the late Peter Cooke of Coventry & District Natural History Society. Felt gall on Holm Oaks should be obvious.

Globular Kidney Galls of the gall wasp Trigonapsis megaptera on an epicormuc twig on the ble of an oak tree along Digby Avenue, wollaton Park. There are three galls varying from brown to a light yellowy-green, and of slightly different sizes (6-10 mm). They differ from other spherical galls in not being hard and woody.
