Protostropharia semiglobata, commonly known as the hemispherical stropharia, the dung roundhead, or the halfglobe mushroom, is an agaric fungus of the family Strophariaceae. The mushrooms have hemispherical straw yellow to buff-tan caps measuring 1–4 cm (0.4–1.6 in), greyish gills that become dark brown in age, and a slender, smooth stem 3–12 cm (1.2–4.7 in) long with a fragile ring.
A common and widespread species with a cosmopolitan distribution, the fungus produces mushrooms on the dung of various wild and domesticated herbivores. Accounts differ as to whether it is edible or perhaps poisonous.
