Description
Mushrooms can be classified into poisonous, edible, and unknown varieties. Unknown mushrooms are those whose chemical profiles are not known, flesh is thin and not worth eating, or too small to eat. This year, the last collection of the mushroom series stamps features four unknown species of mushrooms: Pseukdocolus schellenbergiae, Cyptotrama asprata, Laccaria vinaceoavellanea, and Phallus rugulosus.

Phallus rugulosus.
Looking like a picket with a peaked hat on its head, Phallus rugulosus belongs to the "Phallus genus" of the "Phallaceae Family". It is characterized by a cone-shaped cap with silk-textured gills on the surface. Its dark-brown body is covered with blackish brown slime and gives forth a foul odor. It usually occurs in autumn in areas where mixed forest has been recently slashed and burned to allow for cultivation.
