Where to find Milk-white Toothed Polypore

Deciduous Forests

Commonly found in deciduous forests across temperate regions, growing on fallen logs, branches, and stumps of various hardwood species.

Mixed Forests

Can also be found in mixed forests where hardwoods are present, though less frequently on conifers.

Urban and Suburban Areas

May appear on dead wood in parks, gardens, and other urban or suburban settings where suitable hardwood substrates are available.

Foraging tips

  1. Substrate Preference. Focus your search on dead hardwood, especially oak, maple, birch, and beech. Look for logs and branches that are well-decayed but still firm enough to support fungal growth.
  2. Growth Habit. Observe the growth pattern. It often forms extensive patches on the underside or sides of logs. The effused-reflexed form will have a small, projecting cap-like edge.
  3. Hymenophore Transformation. Pay close attention to the hymenophore. The transition from pores to flattened teeth is a key diagnostic feature. Younger specimens might still show more poroid characteristics.
  4. Color and Texture. Note the white to cream color and the tough, fibrous texture. The upper surface, if present, will be finely hairy.

Quick Check

Substrate:
Dead hardwood.
Fruiting:
Resupinate to effused-reflexed, white to cream, with a hymenophore that develops into flattened teeth.
Odor:
Indistinct or slightly fungal.
