Introduction '''''Gigasperma''''' is an inactive genus of fungi in the order Agaricales with a single species. It was treated either as the only genus in the monotypic family '''Gigaspermataceae''', or part of the wider Cortinariaceae. ''Gigasperma'' was circumscribed by Austrian mycologist Egon Horak in 1971.
Taxonomy No species remain within this genus since ''Gigasperma'' ''cryptica'' was reclassified as ''Thaxterogaster crypticus'' in 2022''.''
