Not Ghostbusters slime … but Mycetozoa – slime moulds, more discovered this time in local woods. This species looks to be the same as in the previous post Trichia botrytis. Like all slime moulds, they creep across a surface very slowly devouring food until they run out, and when they run out they will release their spores.
These appear to be in the early stages of ripening. Each Sporocarp – the bright fruiting bodies you see – are around 5 mm (1/4 in) tall and 0.8 mm (3/64 in) in diameter, so they can be easily missed out in the field unless you keep an eye out for them. These were found on the underside of fallen bark on the ground.
