Leucopaxillus giganteus is an uncommon worldwide species of saprobic fungus with a cap that can reach a diameter of up to 45 cm. The funnel-shaped cap is white/pale cream and has cream gills which run down the stem. The spore print is white.
The stem is typically 4 to 6cm tall and 2 to 3cm in diameter. It is initially creamy white, turning a buff colour.
It is typically found in late summer to late autumn, growing in groups or rings in grassy pastures, roadside hedges, or woodland edges.
Leucopaxillus giganteus contains a number of bioactive compounds, one of which has displayed antibiotic and anti-tumour properties in laboratory tests.
