Dryad's Saddle Identification (Cerioporus squamosus)

Check the fruiting body shape, attachment, and pore surface first.

• Caps are broad and fan- to kidney-shaped, often overlapping in shelves on wood.
• A single cap is often 4-12 inches (10-30 cm) across, with a thick, rounded outer edge.
• The top is pale tan to cream with darker brown scales, giving a mottled, pheasant-back pattern.
• Instead of gills, the underside has large, angular pores that run slightly down the short stem.

A dark, off-center stem attached to wood supports the cap rather than a central stalk from soil.

Dryad's Saddle shows clear visual changes as each fruiting body expands and ages.

• Young plant: New fruiting bodies begin as thick, rounded knobs or fan-shaped buds. The upper surface is pale and only lightly patterned before the dark scales stand out clearly.
• Mature plant: At maturity, the cap broadens into a shelf or semicircle, often 4-12 inches (10-30 cm) across, with distinct brown scales over a tan background.
• Fruiting stage: The underside starts with very fine pores, then develops larger angular pores that become easier to see. The flesh also shifts from tender to tougher with age.

Dryad's Saddle is most noticeable in spring and early summer, when fresh brackets appear on trunks, stumps, or fallen wood. Young caps look pale tan with dark brown scales and a thick, rolled edge. As they age into summer, the caps broaden, flatten, and often fade. Older fruiting bodies become tougher and less distinct, so the fresh spring stage is the clearest seasonal clue.

A few bracket fungi can be mistaken for Dryad's Saddle at a glance.

Cerioporus squamosus is native across much of Europe, Asia, and North America. It is usually found in deciduous woodland, parks, and along streams or roadsides where broadleaf trees are present. For identification, habitat is useful because this fungus grows on living or dead hardwood, especially trunks and large fallen logs. Finding it on hardwood in these settings helps separate it from similar bracket fungi more often tied to conifers or drier sites.

This mushroom is not a skin-contact hazard, but identification matters because mushrooms can be confused and some look-alikes cause poisoning if eaten.

• Misidentification risk: Ingestion is the main concern for humans and pets. Cerioporus squamosus grows on wood and has large pores under the cap, not gills. Confusion with gilled mushrooms on wood is a more serious safety issue because some are poisonous.
