Clearing away some leaf litter at the weekend, I found this dead leaf from the Beech tree covered in a neat pattern of white spots. Not a fungus, it turns out, but a slime mould. I couldn’t really find one looking quite like this on-line, so I didn’t yet work out the species, which anyway appears difficult, so it goes down as “Myxomycetes sp”,

These slime moulds are single celled animals, that cluster together and reproduce by forming these while spherical fruiting bodies, which ultimately release spores into the air. Surprisingly slime moulds are not static, but slowly move around in a search for food; apparently even being able to traverse mazes in pursuit of a suitable meal.
