Conocybe siligineoides, also known as cone caps, Ya'nte, Ta'a'ya, or Tamu,[1] is a species of macro-fungus in the family Bolbitiaceae. It has seldom been observed by the mycological community with all specimens having been collected in Mexico. Originally reported as a sacred mushroom, no chemical studies have been undertaken on this species although other members of the same genus have been shown to contain psilocybin, which causes strong hallucinations.[2] They are crushed, dried, and used in tea, and consumed fresh.[1]


It is a thin, small, about 3 inches (7.6 cm) in height, mushroom that is reddish-orange with a cone or bell shaped cap. When spores are forming the cap will turn a rusty color.[1]

Traditional uses

The Mazatec used this fungus as an entheogenic. The Aztec called them sacred mushrooms and used them for healing and various rituals. A cult in the Ivory Coast of Africa has found to be centered on "Tamu".[3][4][5]
