This page of our Control guide contains a walkthrough for a side mission called Removing Mold. You will learn, e.g. where to find the three infected enemies and how to eliminate them.
The mission starts in: Dr. Underhill laboratory. Enter the elevator shaft in Central Research in the Research, use Levitation to mitigate the fall damage and talk with the woman. A more detailed description of reaching that place in the walkthrough for the Old Growth side mission.
Walkthrough: Your task is to eliminate targets infected with mold. They're in three different locations. To make the search easier, the developers have prepared a hint. The infected can be located through mold, which appears on the ground and walls near their locations, which means that the target is close.
The infected is in Extrasensory Lab.
The second target is nearby, in the room with wooden racks.
The last target is in the passageway leading to Parakinesiology.
Use the elevator in Ritual Division and travel to the top floor.
The second target is waiting in the Synchronicity Lab, on the upper level.
The third target is in the bathroom, next to the Luck & Probability room.
First target is beyond the door number one.
Another target is in the bathroom.
The third target is in an isolated room - use levitation to get to it.
