Sterigma

A sterigma (pl. sterigmata) is an extension of the basidium (the spore-bearing cells) consisting of a basal filamentous part and a slender projection with a spore at the tip.[1] They are formed on the basidium as it develops and undergoes meiosis, to result in the production of (typically) four nuclei. The nuclei gradually migrate to the tip of the basidium, and one nucleus will migrate into each spore that develops at the tip of each sterigma.[2]
