Other types of mushrooms have pores instead of gills. Like gills, pores produce spores, but they appear as small, sponge-like holes instead of thin blades. The little holes lead to tubes inside the cap. As spores mature, they eventually fall from the tubes out of holes and into their environment.

The normal liver cells or hepatocytes contain lipid droplets, more frequent near the central vein of hepatic lobules, that can be demonstrated using osmium tetroxide as fixative. In steatosis or fatty liver disease, the amount of lipid droplets is pathologically very increased.

Phallus impudicus Pers. syn. Ithyphallus impudicus (L.) Fr. Gemeine Stinkmorchel Phallus Impudique, Satyre puant, Oeuf du diable, Stinkhorn. Fruit body initially semi-submerged and covered by leaf-litter, egg-like, 3–6cm across, attached to substrate by a cord-like mycelial strand. The outer wall of the egg is white to pinkish but there is a thick gelatinous middle layer held between the membranous inner and outer layers. The egg is soon ruptured, as the white hollow stalk-like receptacle extends to 10–25cm high, the pendulous, bell-shaped head is covered by a meshwork of raised ribs covered in dark olive slime which contains the spores. This slime has a strong sickly offensive smell which attracts flies from large distances, the slime sticks to the legs of the flies and thus acts as a means of spore dispersal which takes place very rapidly, exposing the underlying mesh of the cap. Spores pale yellow.
