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

Thanks so much for your comments @Teresa . Unfortunately I wasn't able to head back to gather further observations. Will keep your helpful comments in mind for next time I come across slime mould though!

Mucilago crustacea goes through a white plasmodial stage and is generally associated in grassy areas rather than on chip mulch. Are you able to revisit this today or tomorrow to observe the mature stage? We we last saw some similar to this it took five days to mature before we could positively say it was a Fuligo species, most probably F. septica; its impossible to be 100% certain without microscopic examination, perhaps you can do some micros or collect and lodge at the herbarium.

Stunning find so close to the sea. Do hope you can follow up and revisit this one in a few hours or first up tomorrow to see what it changes into - great shot

Thanks Lisa, we found four different species yesterday, so thrilling - still doing micros to determine species
