Are there any fungi that can tense their tendrils?
It'd be cool if their were small dirt creatures which lumbred around powered by a network of fungi, which effectively ate their own bodies.
Nematophagous fungi lasso and kill/digest nematode worms, that's probably as close as it gets desu
Some fungi are capable of trapping nematodes

Alright, the real question is, can I breed fungi that make complex structures yet can tense?
