Robellini Trunk Fuzz = Lichen (Harmless), Queen Palm Frizzling = Check for Ganoderma

Robellini trunks: greenish powder = lichen (normal). Queen palm: sparse, fronds falling, fertilized 3–4 mo ago. No conk yet. Robellini stump 6 ft away has conk.

Robellini

Lichen = harmless epiphyte. Ignore.

Queen Palm

Ganoderma spores travel. 6 ft = high risk.
No conk yet = maybe escaped.
Fertilize, water, pray. If conk appears → remove fast.

Other Queen 6 ft Other Side

Same risk. Monitor. No prevention exists.
