Dung Roundhead - Stropharia semiglobata

A small fungus associated with herbivore dung.  The hemispherical cap is sticky when wet, smooth and shiny when dry and varies in colour from pale cream to ochre. Gills are greyish-brown.  The stem is whitish, sticky under the thin ring and darkening towards the base.  The ring is white at first but becomes purple-brown as spores are released. 

Other small mushrooms may be found on dung - e.g. Deconica species
