 Multiple numbers of basidiospores can result, including odd numbers via degeneration of nuclei, or pairing up of nuclei, or lack of migration of nuclei.For example, the chanterelle genus "Craterellus" often has six-spored basidia, while some corticioid "Sistotrema" species can have two-, four-, six-, or eight-spored basidia, and the cultivated button mushroom, "Agaricus bisporus".can have one-, two-, three- or four-spored basidia under some circumstances.
