Black morel or false morel? How to tell them apart
Black morel is edible only with care, while the false morel is a deadly poisonous mushroom. Compare the two mushrooms point by point.
Deadly poisonous. The false morel has a brain-like folded head without pits, and its interior is divided into many chambers; the morel – regular pits and a single hollow chamber.
The black morel has a conical head with pits in vertical rows and a single hollow chamber; the false morel – irregular, brain-like convolutions.
Feature by feature
| Feature | Black morel | False morel |
|---|---|---|
| Edibility | Edible with care | Deadly poisonous |
| Cap | Head 3–7 cm across, elongated, bluntly conical, grey-brown, olive-brown to blackish; pits elongated, arranged in vertical rows between lengthwise ribs; hollow inside. | Head 5–15 cm wide, irregularly globose, strongly brain-like folded (convolutions, no pits), yellow-brown through chestnut-brown to blackish-brown. |
| Under the cap | No gills or tubes – the spore-bearing layer is in the pits of the head. | No gills or tubes – the spore-bearing layer covers the outer, folded surface of the head. |
| Stem | Whitish to cream, narrower than the head; the margin of the head stands slightly away from the stem at its base (a sinus-like notch) – a feature distinguishing it from Morchella elata. | Short and thick, irregularly furrowed, dirty white with purplish-brown spots; with a few irregular channels inside. |
| Flesh | Brittle, waxy, whitish; head and stem form a single hollow chamber. | Brittle, cartilaginous, whitish; the interior of the head is divided into irregular chambers, cream-coloured. |
| Smell and taste | Smell and taste pleasant, indistinct. Spore print dark cream, yellowish. | No distinct smell or taste. Spore print cream. |
| Habitat | In early spring in damp, light places: forest edges, scrub, stream valleys (more common in the mountains, often near butterbur), and also parks and gardens – especially on freshly spread bark mulch in its first or second year. Red List: R. | In early spring in pine forests on sandy soils, often in clear-cuts, young stands, plantations and in places with disturbed ground (churned-up litter, edges of roads and streams). Fairly common in Poland. |
| Season | March, April, May | March, April, May |
How to recognise it: black morel
- Spring, often on bark mulch in gardens and parks
- Dark, conical head with pits in vertical rows
- Margin of the head stands slightly away from the stem
- A single hollow chamber inside
- Never eat raw
How to recognise it: false morel
- Spring in pine forests on sand
- Head brain-like folded, without pits
- Chestnut- to blackish-brown
- Interior divided into many chambers (morel – a single hollow chamber)
- Vapours from cooking are also toxic
Safety rule
Never eat a mushroom identified only from a website, a photo or an app. Show any doubtful specimen to a certified mushroom inspector at the sanepid (state sanitary inspection); in season the advice points are free. Do not give wild-picked mushrooms to children.

Black morel or false morel: how can you tell them apart?
Deadly poisonous. The false morel has a brain-like folded head without pits, and its interior is divided into many chambers; the morel – regular pits and a single hollow chamber. The black morel has a conical head with pits in vertical rows and a single hollow chamber; the false morel – irregular, brain-like convolutions.
False morel: what to do if you have eaten it?
Call 112 at once or go to A&E (SOR), and take any leftover mushrooms with you. Gyromitrin, metabolised to monomethylhydrazine (MMH); damages the liver, kidneys, nervous system and red blood cells (haemolysis). First symptoms usually after several to a dozen or so hours: nausea, vomiting, diarrhoea, dizziness, loss of coordination, seizures, coma, liver failure. The antidote is intravenous vitamin B6. Poisoning by inhalation during heat treatment is possible.
