Panaeolus semiovatus

Cap	Hemispherical or like half an egg (hence the specific name); 2 to 6 cm in diameter; clay coloured or cream-brown; drying smooth and shiny but tending to wrinkle in dry weather. The cap flesh is thin and off-white.
Gills	Off-white becoming mottled brown and darkening to black as the spores mature; often paler at the edge; adnate and crowded.
Stipe	The stipe (stem) is tall and slender. Although the lower two-thirds of the stipe is the same colour as as the cap, the colour becomes noticeably paler towards the apex. A white, fragile, superior (upwards facing) ring persists to maturity. The stem flesh is yellowish and very brittle.
Spore print	Black.
Odour/taste	Not distinctive.
Habitat	On or beside dung, particularly on upland meadows and common land.
Season	Mainly May to November, but these fungi may appear throughout the year if there is a spell of mild weather.
Occurrence	Fairly frequent.
Similar species	Stropharia semiglobata, the Dung Roundhead, is more spherical, has a transient ring and leaves a brown spore print.
