Pale oyster or Branching oyster
How they differ, how to recognize them and which is more dangerous — a mushroom comparison
The short answer
Pale oyster and Branching oyster are similar species that can be mixed up while foraging. The main visible difference: size: Pale oyster — medium (5–15 cm), Branching oyster — large (over 15 cm). The mushrooms also differ in the following features: cap color, cap shape, cap surface.

🔬 Morphology
Cap
Pale oyster
The cap of the pale oyster reaches 4 to 8, occasionally up to 15 centimeters across. It is fan-shaped, tongue-shaped or almost semicircular, with a thin, often wavy or slightly split margin. The surface is smooth, dry and matte. The coloring is pale: whitish-gray, cream or pale ocher, often darker where it attaches to the wood; with age and in sunlight the cap turns noticeably yellow. It's this pale, almost white color that sets the species apart from the grayish-brown oyster mushroom.
Branching oyster
Cap up to 15 cm across, funnel-shaped with a deeply sunken center — the hallmark of the species (hence the name “cornucopiae” — “horn of plenty”). Whitish when young, turning creamy brown or ocher with age. Surface smooth, slightly sticky in wet weather. The margins are often wavy, sometimes raggedly torn.
Hymenophore
Pale oyster
The underside has gills. The gills are white or cream, fairly distant and thick, running noticeably down the stem, and where there is no stem, running all the way down to where the cap attaches. The spore print is white or with a barely noticeable lilac tinge. Decurrent white gills that stay pale for a long time are a characteristic feature of oyster mushrooms.
Branching oyster
The gills run far down the stem and form a distinctive network (“anastomoses”) on the lower part of the stem — the gills interweave like a cobweb. White, cream with age. Spore print white or pale lilac.
Stem
Pale oyster
The stem is short or almost absent, usually lateral or off-center, up to 4 centimeters long, dirty white, downy-hairy at the base. Several mushrooms often grow together at the stems in a single cluster. The stem flesh is tough, especially in mature specimens, so mostly the caps are eaten. There is no ring and no volva.
Branching oyster
A stem is always present (unlike the oyster mushroom, where it often almost merges with the cap), 3–12 cm tall, 1–2 cm thick. Sometimes branched, central or slightly off-center. White, cream in mature ones. Tough and fibrous in old ones.
Flesh
Pale oyster
The flesh is white, tender and juicy in young mushrooms, becoming firmer and fibrous with age, especially closer to the stem. It does not change color when cut. The taste is mild and pleasant, with no bitterness. For the table, choose young caps with tender flesh.
Branching oyster
The flesh is white, springy in young ones, getting tougher with age, especially in the stem. It does NOT change color when cut. The texture is like the oyster mushroom’s, but a little denser and springier.
Smell
Pale oyster
The smell is pleasant and mushroomy, sometimes with a barely perceptible hint of anise or flour. The aroma is fresh and not sharp, so for identification rely first of all on the pale fan-shaped cap, the decurrent white gills and growth in clusters on hardwood.
Branching oyster
The smell is distinctive — a blend of anise and flour notes over a faint mushroomy base. Stronger in young specimens. The taste is mild, with a hint of hazelnut.
