Autumn galls

Brede High Woods is entering its autumn phase now.  After the recent rains fungi are abundant and many of the trees are starting to turn colour.

One new record was of the ground ivy gall (Liposthenus latreillei or glechomae) caused by a small cynipid wasp.  Round galls like his are mostly found on trees and shrubs and it is quite a surprise to see them on such a low growing plant.

Maybe their being close to the ground accounts for the fact that they are called cat's testicles in Hungary.
