And yes, that is brown slime around the edges.
Mmm, could this be my inspiration for the KAL?
Edited: I have just done some googling and found my triffid. It appears to be a member of the Stinkhorn Fungi (charming), the slime can smell like sewerage or rotting meat (even more charming), the smell is attractive to dogs and consumption can kill small dogs, if humans ingest them they are to seek urgent medical attention!! I guess I’ll be removing them from my garden & looking elsewhere for inspiration for the KAL. Do I really want a Stinkhorn Fungi scarf?
