Seta (mycology)

Setae in the fruit layer of Hymenochaete damicornis under the light microscope

Setae (plural from Latin seta ~ bristle) in mushrooms are thick-walled, rigid and pointed ends of mushroom threads ( hyphae ), which are usually pigmented in the cell wall . They can appear as hair, sterile elements in the fruit layer ( paraphyses , cystids ) or other surfaces of the fruit body , but also in the flesh ( trama ) or fungal tissue ( mycelium ). Setae are not homologous formations, for the designation as Setae only the spear-like shape is decisive.
