Mealybug Infestation

The white cottony masses are characteristic of mealybugs, which secrete a waxy substance to protect themselves. These pests suck the sap from the succulent body of the Conophytum, leading to shriveling and potential rot.

Very Common

Fungal Mycelium (Botrytis/Mold)

High humidity or poor airflow around the Conophytum's fleshy leaves can cause fungal spores to bloom as white, fuzzy mycelium. This often occurs if the substrate remains damp for too long during the plant's dormant period.

Common

How to confirm: Check if the white spots are accompanied by soft, mushy tissue on the body of the plant.

Powdery Mildew

This fungal disease manifests as a powdery white coating on the surface of the plant. While more common in leaves of larger succulents, it can affect the outer epidermis of Conophytum if environmental conditions are stagnant.

Common
