Weraroa

thumb|right|A cross-section of the type species Weraroa novae-zelandiae (Psilocybe weraroa).

Weraroa was a genus of mushrooms from the families Hymenogastraceae and Strophariaceae. 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 was thought that the genus represented an intermediary evolutionary stage between a hypogeous (underground) ancestor and the related epigeous (above ground) genus Stropharia. Advances in phylogenetics and taxonomic changes since 1958 found it contained unrelated species from multiple genera. It is now considered a synonym of the genus Psilocybe.
