Dung Roundhead (Protostropharia semiglobata) This strange little mushroom was about 90mm tall with a cap only about 12mm wide. <br />
The stem was very straight and narrow with an unusual undulated annulus, sticky but firmly attached. <br />
There seemed to be some black within the gills but white material seems to have settled on the ring. <br />
Cap was very viscid and almost spherical.<br />
Found growing on a grassy and rocky path in a national park.<br />

"'Protostropharia semiglobata'', commonly known as the dung roundhead, the halfglobe mushroom, or the hemispheric stropharia, is an agaric fungus of the family Strophariaceae. A common and widespread species with a cosmopolitan distribution, the fungus produces mushrooms on the dung of various wild and domesticated herbivores. The mushrooms have hemispherical straw yellow to buff-tan caps measuring 1–4 cm , greyish gills that become dark brown in age, and a slender, smooth stem 3–12 cm long.. more
