Dark-brown Wood-hair

Stemonitis fusca

Also known as Chocolate Tube Slime, Pipe Cleaner Slime Mold, Chocolate Tube Slime Mold

Dark-brown Wood-hair starts life as a microscopic, single-celled amoeba before merging into a slimy plasmodium that creeps through moist wood to engulf bacteria and fungal spores. When mature, it transforms into clusters of delicate, hair-like chocolate brown stalks that rise from the decaying wood surface. These fruiting structures eventually release millions of tiny airborne spores to colonize new damp forest habitats.
