Artist's Conk
Ganoderma browniiAlso known as Brown's Artist's Bracket, Pacific Artist's Conk
Hard, shelf-like bracket fungi form perennial growths along the trunks of broadleaf trees, particularly California bay laurel in West Coast forests. The stark white lower pore surface darkens instantly when scratched or pressed, creating a permanent canvas for fine line drawings as the specimen dries. As a heart-rot pathogen, it slowly decomposes heartwood inside older trees, creating essential nesting cavities for forest wildlife.

- Very high
- Why interaction risk is low
- Many wild mushrooms have toxic look-alikes; never eat wild fungi based on app identification alone.
Responsible observation
- Observe the pore surface: Fresh white undersides turn dark brown with gentle pressure or light etching.
- Inspect host trees: Look for heavy bracket formations low on mature California bay or oak trunks.
- Leave in place: Allow brackets to remain attached to continue dispersing spores into the surrounding woodland.
