Look-alikes: The similar-looking Smooth White Parasol Leucoagaricus leucothites has no green colour in the cap and no Traditionally known as Leucoagaricus naucinus, most mycologists now regard this name as a synonym of Leucoagaricus leucothites, which has nomenclatural priority.Fieldmarks include a whitish, glabrous cap, sometimes tinged buff to pale-grey, gills that are tinged pinkish at maturity, and a sub-bulbous stipe that bruises yellowish to brown on handling. Although these mushrooms are generally considered edible, some authorities say that White Dapperlings are slightly poisonous. Lookalikes: Amanita virosa-- vulva (cup at base of stem), skirt-like ring It lacks a universal veil, so it does not feature warts or patches on the cap, nor a volva at the base of the stem - but it could be easily mistaken for an Amanita on casual inspection.

Saprobic; growing alone or gregariously in grassy areas or on the disturbed ground (roadsides, cultivated areas, and so on); often in the vicinity of conifers (the most impressive fruiting I have seen occurred in a lawn where a spruce tree had been removed the previous year); occasionally appearing in woods; late summer through fall (but sometimes found in spring); widely distributed and common throughout North America. Leucoagaricus is derived from the Greek Leucos meaning white and Agaricus, the genus name of the 'true mushrooms' as many people call the Field Mushroom, Horse Mushroom and their close relatives all of which have pink gills that darken when the brown or purple-brown spores mature. Clitocybe dealbata is a small, pale mushroom with a slightly rounded cap; other Clitocybe species often have an upturned, funnel-shaped cap with the gills running partway down the stem ( decurrent gills).
