Why it matters

Gill color, spacing, thickness, branching, and attachment to the stem are major identification features. They also change with age as spores mature.

What it does not prove

Gills do not prove a mushroom is an agaric, edible, mature, or safely identified.

What to check
  • Record whether gills are free, attached, decurrent, or otherwise connected to the stipe.
  • Note spacing, thickness, branching, and short gills.
  • Compare gill color with spore-print color.
  • Observe bruising, latex, or age-related changes when relevant.
