🔬 Morphology

Cap

Pig's ear

Fruiting body funnel-shaped or spatula-like, 4-15 cm tall and wide, with an uneven wavy or deeply cleft edge. It often grows as a cluster of “ears” fused on a common base. Upper surface color: young ones are violet-lilac, turning purplish brown to brown with age; the center is darker, the edge paler. The surface is smooth, faintly shiny in wet weather and matte in dry.

Horn of plenty

Fruit body funnel-shaped or tubular, 3–10 cm tall and 2–6 cm across, with no clear boundary between cap and stem. The outer (upper) surface is dark gray or blackish brown, slightly scaly. Margin wavy or irregularly lobed.

Hymenophore

Pig's ear

The hymenophore is not gilled and not tubed — it consists of folds and wrinkles running down the “stem”, uneven, forked and blunt (like a chanterelle's but coarser). Color violet-lilac to purplish brown, paler than the top of the cap. Spore print yellowish ocher.

Horn of plenty

The hymenophore is on the outer surface of the fruit body — smooth or slightly wrinkled, with no true gills or false gills. Gray or bluish gray, with a powdery bloom of spores. This feature sets it apart from the hymenophore of true chanterelles.

Stem

Pig's ear

There is no separate stem — the fruiting body is one piece, funnel-shaped. The lower part narrows into a sterile base 2-5 cm high, the color of the hymenophore or slightly paler.

Horn of plenty

There is no stem in the classic sense — the fruit body is one continuous cone-shaped tube. The lower part is narrowed, hollow inside, and the whole structure is open from top to bottom. Grayish or brownish black.

Flesh

Pig's ear

The flesh is whitish to yellowish, firm in young ones, fibrous in old ones. It doesn't change color when cut. It has a pleasant, mild taste.

Horn of plenty

Flesh very thin, brittle, gray or blackish. Taste delicate, pleasant, slightly nutty. When dried it concentrates, taking on a rich, intense, truffle-like flavor.

Smell

Pig's ear

A faint, pleasant mushroomy smell, sometimes with a fruity note. The taste is mild, with nothing sharp.

Horn of plenty

Smell unobtrusive, pleasant, slightly floral and woodsy in fresh mushrooms. When dried, the aroma intensifies sharply and becomes deep, earthy and truffle-like. That's exactly what makes the dried horn of plenty such a valuable culinary ingredient.
