Lepioata cristata is a widely distributed species in North America, Europe, Northern Asia and New Zealand and it is commonly known as ‘stinking parasol’. The common features of this species are flat, brownish scales on the cap, bald stem having fragile ring and a sharp odor.

L. cristata commonly grows in disturbed grounds (lawns, paths) and under the wood stumps (hardwood or conifer). It has 2-4 cm bell shaped cap. Mature species consist brownish scales arranging as concentric rings on the cap and the center of the cap remains bald and darker (Figure 1). L. cristata is a gilled mushroom and the gill arrangement is free from the stem. The stem of L. cristata is typically 3-7 cm long with a white fragile ring which may disappear at early stages and the basal mycelia are white. The spore print of L. cristata is white and spores are 5-8 x 2.5-4 µ. Theses spores are wedge shaped with a flattened bottom (Figure 2).
