Lepiota decorata, also known as the pink parasol, is an uncommon species of gilled mushroom found in North America. The cap of L. decorata usually has a speckled violet pattern, stains orange when scratched, and is about 4 to 8 cm in diameter.
Lepiota decorata is often found in rich soil and leaf litter below trees including coast live oak, alder, eucalyptus, and conifer. A similar, separate, as-yet-undescribed species is associated with Monterey cypress. Leucoagaricus roseolividus, a much more common mushroom, has a superficially similar appearance. L. decorata is possibly properly a Leucoagaricus but has not yet been moved over. Lepiota decorata was first described in Mycologia magazine by S. M. Zeller in 1929.
