I know little more about mushrooms than that they make good photographic subjects: they sit still (most of the time), and they contrast well with their surroundings.
Today my brother, his girlfriend and I went to Baarn in Utrecht to traipse around both the current and former park of Groeneveld Castle. More photos below the fold.
The last mushrooms of the day were two clusters that looked like they were melting (they were actually dripping). To be more precise, they looked like melting meat. Note the fly gorging itself on the melting meat in the close-up.
