Lepista tarda is very similar to Lepista (Clitocybe) nuda, the Blewit, a well-known and choice edible mushroom common to Europe and North America but unknown in Hawai‘i. Lepista tarda differs from the Blewit in forming more delicate, thin-fleshed caps, but like L. nuda is an excellent, tasty mushroom. This medium-sized mushroom is easily identified by its vivid purple color in young, moist specimens. Besides lawns, L. tarda is also found in banana patches, bamboo thickets, around compost piles, and in montane pastures. Is: HA, KA.
