Category Archives: Slime Moulds

Slime moulds are not a plants or animals. They are a huge collection of single-celled organisms called Protozoa. When the conditions are correct (similar to lawn fungi) they bloom and spore in huge numbers. This is the structure which becomes a slime mould. Once they release their spores for the next generation, they collapse and die.

Slime moulds on lawns

A slime mould can look like an extremely odd growth on a lawn, almost alien. They appear quickly and can disappear almost as quickly.

They can be yellow, white or grey and black. They cover all areas of the UK but only appear on lawns when the conditions are right for them. Usually humid conditions, such as early spring.
