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.

[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.

A cult in the Ivory Coast of Africa has found to be centered on "Tamu".
