Look at the underside of a log, and you’ll find my new obsession: the beautiful, bonkers world of slime moulds

A few years ago, I started looking at the underside of logs and it changed my life. I found a secret carnival of the most bodacious and interesting organisms I had ever seen. Bubbles of candy-pink gloss on stilts (Comatricha nigra), bunches of rainbow iridescence on toffee strings (Badhamia utricularis), bouffants of raspberry parfait (Arcyria denudata) – and those are just a few that have appeared on bits of wood in our urban garden.
