Slime Moulds


Slime moulds are a diverse group of organsims that are neither plants, animals nor fungi. They spend most of their life as microscopic single-celled amoeboid individuals in leaf litter, soil or decaying wood, and when conditions are right they reproduce and form a larger, spreading structure called a plasmodium, which in turn produces fruiting bodies (Secretive Slime Moulds: Myxomycetes of Australia By Steven L. Stephenson). 

For beginners, here is a “A Key to Common Genera of Slime Moulds” written and illustrated by Peta McDonald, a Melbourne primary school teacher: https://upload.wikimedia.org/wikipedia/commons/f/f6/A_Key_to_Common_Genera_of_Slime_Moulds.pdf

A more technical key can be found in “Taxonomic Keys and Plates from The Myxomycetes”, a book by George W. Martin and Constantine J. Alexopoulos: https://www.myxotropic.org/wp-content/uploads/2021/04/MyxoKeys.pdf

For a photo gallery of slime moulds from around the world check out this one on a Spanish myxomycetes website: https://www.myxotropic.org/galeria/

This one will not become more yellow with age; generally the pale yellow ones will harden, then generally change to a brownish shade before cracking to release the spores
