Photos

Appearance

Cap

Measuring 2 to 10 centimeters across, it is fan-shaped or shell-shaped and often appears in overlapping groups or shelves. The color ranges from white or cream to beige or tan, and the edges may show fine lines.

Stem

Very short or nearly absent, typically attached to the side of the cap. It is white and can reach up to 4 centimeters in length.

Gills

Crowded and closely spaced, running deeply down the stem. They begin white and may turn a yellowish-cream color as they mature.

Flesh

White and relatively tough in texture.

Spore print

Varies from white to lilac.

Smell

Mild with a scent reminiscent of flour or ammonia.

Edibility

This species has a mild flavor and can smell of flour or ammonia, though the white flesh is described as quite tough. It can be confused with Pleurocybella porrigens or Pleurotus dryinus, the latter of which is distinguished by a cottony ring on the stem. Other lookalikes include Pleurotus ostreatus, which typically has a brown cap and fruits in cooler weather, and Pleurotus populinus, which grows exclusively on poplar or aspen and lacks a lilac spore print.

Nutrient Source

It obtains nutrients by breaking down dead organic matter, such as wood and decaying plant material.
