Black-stalked Marasmius
Tetrapyrgos nigripes
A species of Tetrapyrgos.
The diminutive fruiting body of the black-stalked Marasmius (Tetrapyrgos nigripes) presents a peculiar aesthetic, almost as if its cap and stem originated from separate fungi before being joined. This unusual pairing results in a distinct and easily recognizable look. These mushrooms are remarkably small, typically not exceeding the dimensions of a bottle cap. They exhibit a preference for emerging from small organic debris like twigs and fallen leaves.
