Weraroa is a genus of mushrooms in the Strophariaceae family. The genus was initially described by mycologist Rolf Singer in 1958 to accommodate the single species Secotium novae-zelandiae reported by Gordon Herriott Cunningham in 1924. It has been suggested that the genus may represent an intermediary evolutionary stage between an hypogeous (underground) ancestor and the related epigeous (above ground) genus Stropharia.
