Lepiota maculans
''Lepiota maculans'' is a rare species of agaric fungus in the family Agaricaceae. It was originally collected in Missouri, and then 105 years later in eastern Tennessee. It is the only member of ''Lepiota'' known to have a pink spore print instead of the usual white or cream color. The fruit bodies have caps up to in diameter, with brownish, sparsely scaled centers. The gills are closely spaced, not attached to the stipe, and discolor reddish at the edges.
==Taxonomy==
The species was first described in 1905 by American mycologist Charles Horton Peck. The type collection was made by physician and amateur botanist Noah Miller Glatfelter from St. Louis, Missouri. Peck characterized it as a "small but pretty species, easily known by the flesh of both pileus and stem changing to a reddish color where wounded and by the lamellae assuming a reddish or pink color with age or in drying."〔 The mushroom was found again 105 years later in a survey of macrofungi in the Great Smoky Mountains National Park. Molecular analysis of DNA sequence data confirmed its placement in the genus ''Lepiota'', despite its pink-colored spore print (an unusual color for that genus; usual is white or cream). Comparison of the fruit bodies with the original type material demonstrated that, based on the shape, size, and staining reactions of the spores, both collections represented the same species. ''L. maculata'' is classified in the section ''Lepiota'' of genus ''Lepiota'', and is closely related to the European ''L. ignivolvata''.〔
