How to tell White saddle from Pouched false morel

How they differ, how to recognize them and which is more dangerous — a mushroom comparison

Warning: Pouched false morel(Paragyromitra infula)

POISONOUS

Eating it causes poisoning. Do not pick it unless you have identified it with certainty.

Gyromitrin poisoning — similar to G. esculenta. The gyromitrin concentration in P. infula fruit bodies is usually lower than in G. esculenta, but variable and potentially lethal.

Active toxin: GYROMITRIN — the same as in the spring false morels. It is metabolized into monomethylhydrazine (MMH) — a liver toxin, hemolytic agent, neurotoxin and carcinogen (IARC 2B).

Latency period: 6-12 hours (as with the spring false morels).

Symptoms and clinical picture — identical to G. esculenta poisoning. See the full details on the false morel page.

First aid: CALL 112 or your local emergency number, activated charcoal; in hospital — IV pyridoxine (vitamin B6) as a specific antidote, rehydration, liver monitoring.

PREVENTION: do not eat any species of the genus Gyromitra (Gyromitra esculenta, G. gigas, G. infula and others) in any form. No processing method guarantees safety.

If you suspect poisoning, call an ambulance immediately: 112 (the European emergency number) or your local emergency number

🔬 Morphology

Cap

White saddle

Cap 2-4 cm, irregularly saddle-shaped, with 2-4 lobes that look like crumpled fabric. Color white or creamy white, with a yellowish tinge in wet weather. Surface smooth on the outside (where the hymenium is), finely warty underneath. Partly fused to the stem at the top. Margins contorted, uneven.

Pouched false morel

Cap 3-8 cm tall, clearly lobed, miter-shaped, with 2-3 pointed lobes that form a "hood". Overall shape: a bishop's miter or a pointy gnome hat. Surface smooth or slightly wrinkled (not pitted!). Color chestnut-brown to dark brown, deepening to blackish brown in the center. The inner surface of the cap is pale cream and partly hidden.

Hymenophore

White saddle

Smooth hymenium on the upper (outer) surface of the cap lobes. Ascomycete structure — spores form in asci. Spore print white. Spores ellipsoid, smooth, with one large oil droplet.

Pouched false morel

Ascomycete — the spore-bearing surface covers the outer surface of the cap lobes. Spores form in sacs. Spore print yellowish white to pale ocher.

Stem

White saddle

Stem up to 10 cm tall, 1-2.5 cm thick, cylindrical, hollow inside. Color white, smooth to the touch, BUT with prominent lengthwise ribs (grooves) running its whole length. This is the key feature — a ribbed white stem.

Pouched false morel

Stem 3-7 cm tall, 1-2 cm thick, cylindrical, firm when young, hollow when old. Color whitish to cream-gray. Surface smooth with fine lengthwise wrinkles.

Flesh

White saddle

The flesh is thin, waxy and brittle, white. Doesn't change color when cut. Fragile texture — the mushroom easily falls apart if handled carelessly.

Pouched false morel

Flesh thin, brittle, dirty white to cream, does not change color when cut. The cap is partly hollow inside; the stem may be hollow in old specimens.

Smell

White saddle

Faint, nondescript mushroomy smell. Don't taste it raw — potentially toxic.

Pouched false morel

Faint and neutral, with no warning signs.
