Lepiota is a genus of gilled mushrooms, in the order Agaricales. Though they have white spores, they are related to the familiar brown spored mushrooms of the genus Agaricus. They typically have rings on the stems, which in larger species are detachable and glide up and down the stem. The cap usually has scales: the colours of the cap, gills and scales are important in determining the exact species, as is sometimes the smell.
With respect to mushrooming, this is a genus to be avoided as several species contain amanitins and are highly toxic.[1] Those known to have caused death (or would have caused death except for intensive medical therapy) include L. josserandi in upstate New York in 1986, [2], L. brunneo-incarnata in Spain,[3] and L. helveola.[4][5]
Previously, the most familiar species were the larger species, such as the parasol mushroom and the shaggy parasol. However, these have now been placed in the different genera Macrolepiota and Chlorophyllum. However the status of the genera is not unanimous as some current books still leave the members of Macrolepiota in Lepiota.[6]
