Ganoderma zonatum
Ganoderma zonatumAlso known as Palm Butt Rot Fungus, Zone-Capped Ganoderma
Ganoderma zonatum forms distinctive, woody, shelf-like fruiting bodies on the lower trunks of susceptible palm trees. The upper surface displays reddish-brown concentric zones with a pale growing margin, while the undersurface consists of tiny pores that release microscopic brown spores. Infection causes internal rot near the base of the tree, frequently leading to structural failure and the sudden collapse of mature palms.

- Very high
- Why interaction risk is low
- Many edible mushrooms have toxic look-alikes; never eat wild fungi based on app identification alone.
Responsible observation
- Tree inspection: Check the bottom four to five feet of palm trunks for emerging reddish-brown brackets.
- Preventing spread: Avoid wounding host palms with yard equipment to limit fungal entry points.
