Leucoagaricus roseilividus, commonly known as the rosy parasol, ^[1] is a species of mushroom in the family Agaricaceae. It is found in the Pacific Northwest. ^[1]

Taxonomy

Leucoagaricus roseilividus was first described as Lepiota roseilivida by William Murrill in 1912. ^[2] However, it was later reclassified as Leucoagaricus roseilividus by Erhard Ludwig in 2012. ^[3]

Description

The cap of Leucoagaricus roseilividus is fibrillose. It is purplish in the center and wine-colored or pink outwards. It starts out egg-shaped or hemispheric, later becoming conical. The gills are whitish. The stipe is white, and it is 4–9 centimeters long and 0.3 to 0.9 cm wide. There is a thin ring around the stem that is usually pointed upwards. It sometimes disappears when the mushroom gets older. Lepiota decorata is similar, but is larger and less hairy. ^[1]

Habitat and ecology

Leucoagaricus roseilividus is found in coastal forests ^[4] in the Pacific Northwest. It is found under coastal redwood and Monterey cypress trees. ^[4] It is also found in cedar and alder leaf litter. ^[1]
