Third, The Giant Funnel, Leucopaxillus giganteus, which looks a bit like the Geotropa but with a much shorter, stouter stem and a .larger flatter funnel shaped cap up to 30cm across or more.

Initially ivory white and convex or flat with finely velvety surface and a down-turned margin, the cap of Leucopaxillus giganteus soon becomes funnel shaped and its surface may lose its velvet texture. Use chicken or turkey sausage for a leaner version, and add 2 tablespoons of cream cheese to the mixture to facilitate placing the filling in the caps.
