Habitat: Compost piles, potted plants
Conservation Status: Not of concern
In the PNW, we have at least three greenhouse or compost leucocoprinuses---one is a yellow species related to L. birnbaumii,the second is L. cepaestipes, found in compost heaps, and the third is Leucocoprinus ianthinus (= L. lilacinogranulosus (Hennings) Locquin). In addition to greenhouses, L ianthinus occurs in potted plants. The cap has a finely scaly, purplish to reddish brown center and white margin, often with small purplish fibrils. The gills are white with a slight lilac tint, and the stipe is club-shaped and white to yellowish with purplish fibrils on the lower portion. The ring is white with a purplish edge and it may disappear in age.
