Cerebrumous Spattergroit was a particularly virulent sub-strain of the infectious fungus spattergroit. In addition to the regular symptoms of the disease, such as the formation of purple pustules on the skin, it caused severe confusion and memory loss.
- The cerebrum (Latin for "brain") is the part of the brain comprising the cerebral cortex, as well as several subcortican structures. In humans, it is the largest part of the brain and is the seat of motor and sensory functions, and the higher mental functions such as consciousness, thought, reason, emotion, and memory.
- "Brumous" (from the French brumeux) means "misty, hazy, foggy, wintry".
