Fungus Subtype

The fungus subtype applies to creatures (almost always plants) that are “more fungal” than ordinary plant creatures. It distinguishes common plant creatures like treants from other plant creatures such as shriekers and phantom fungi. Other than the fact that this subtype applies to certain types of plant creatures, fungus creatures have no specific traits. The fungus subtype simply identifies creatures that may be vulnerable to spells, psionics, and effects that specifically target or affect fungi.

Though some of the monsters are classified as hazards (such as yellow mold and russet mold), they still gain the fungus subtype and are considered fungus creatures with regards to certain spells and effects.
