The oak tree in August

 

The oak tree is looking very dark on this cloudy and gloomy (summer’s!) day.
The acorns are growing but some are looking very odd. A quick search on google and it would appear that the misshapen acorns are a type of gall, called the ‘Acorn Knopper Gall’. A small wasp lays it’s eggs into the acorn and as the lavae develop it stimulates abnormal plant growth, creating these complex shapes.
