Gundravian hookspores, a fungal infection that spreads rapidly.
Fungus, or fungi when referring to multiple, encompassed a diverse category of organisms. Examples include lichen, kahel cave fungus, and marsh fungi. These particular examples thrived on the planets of Hoth, Mustafar, and Dagobah, respectively. On the planet Narq, entire forests were composed of blue fungi. Certain fungi, such as the Wirutid, possessed both the ability to move and sentient thought. Some fungal varieties served as the base ingredient for wine production, acting as a substitute for fermented fruit or other vegetation, utilizing a raising agent like yeast. The well-known liquor merchant Derla Pidys once remarked that she had sampled some fungal wines that were "truly remarkable." Furthermore, the fungus served as a food source for the small creature known as the Blismal.
