Black Tar

Mushroom Trees grow throughout the Shivering Isles in two distinct types. A Mushroom Tree (Demenetia)  is a dull plant with a russet-colored star shape on a eggshell-colored cap. From sapling to full-grown tree, the mushroom tree (Demenetia) produces black tar.

Black Tar is a powerful ingredient for poisoners as it has only negative effects. In the youth of the mushroom the tar must be harvested directly from the plant but in maturity the black tar oozes from the tree in rope-like vines.
