Black morel vs common morel: how to tell them apart, with photos

You tell the black morel from the common morel by the cap. The black morel's cap is narrow and pointed, with dark ridges running mostly lengthwise, so the pits line up in rows. The common morel's cap is rounded or egg-shaped, its ridges pale, the same shade as the pits, and the pits are scattered at random. Everything else they have in common: a single cavity running from the tip down to the bottom of the stem, a season in April and May, and both can be eaten only after boiling.

We've already covered when to start your spring forays and why false morels are best left in the forest, in when to pick morels and false morels. This piece is about something else: what these mushrooms really look like, up close and cut in half. All the photos below are our own spring finds, most of them taken in April 2025.

Black and yellow: two groups, not two species

First, a confession from the world of science. For a long time most field guides recognized only a handful of morel species. DNA analysis has shown there are several dozen: as of 2019, about 76 species had been counted worldwide, about 25 of them in Europe. Almost all fall into two large groups: “black” morels with darkening ridges and “yellow” ones with pale ridges. There's also a third, small branch of so-called “white” morels, but foragers rarely come across it.

The name Morchella conica, still used in many field guides, was ruled illegitimate at species level in the 2015 revision of the genus, so modern mycologists don't use it. And European and American morels that look as alike as two peas in a pod often turn out to be different species. Telling them apart reliably is really only possible in a lab.

So what does this mean for a forager? From a photo or in the basket, all you can say with confidence is which group your mushroom belongs to. On our site the “black” ones are described on the black morel page, and the “yellow” ones on the common morel page. We'll stick to those names. (In Ukrainian, “smorchok” and “zmorshok” refer to the same mushrooms: “zmorshok” is the genus name in Ukrainian scientific literature, while “smorchok” is a colloquial form that came from Russian.)

Black morel: dark ridges and pits in rows

We found the black morel in mid-April in a broadleaf wood, among last year's oak leaves. First we spotted one, then, looking closer, four more nearby. The photo shows the key features well: elongated, cone-shaped caps, dark ridges framing paler yellow-olive pits, and short white stems peeping out underneath.

Pick one up and take a close look. The ridges run mostly from top to bottom, with shorter cross-links between them, so the pits line up in vertical rows, like honeycomb stood on its edge. With age the ridges darken even further, to blackish. The cap is tall, 4–8 cm, but only a few centimeters wide.

The second clue is the proportions: a tall dark cap on a short, thick white stem with a finely granular surface. Where the cap meets the stem, “black” morels often have a small groove, as if the cap had been pressed in slightly. There are no rings, scales or membranes on the stem.

And sometimes two mushrooms grow from one thick stem. A few days later, also in a broadleaf wood, we came across just such a pair: two dark caps of different heights and a shared stem that widens noticeably towards the base. This isn't a separate species or a disease; two fruiting bodies simply fused while they were still small.

Common morel: pale, rounded, pits all over the place

The common morel looks completely different. Its cap is rounded or egg-shaped, ochre or light brown, and the ridges are pale, the same tone as the pits. So instead of looking “net-like” like the black morel, it looks spongy. We found it at the end of April in grass on sandy soil, looking like a piece of sea sponge lost in the dry grass.

Look from above and you'll see another difference. The common morel's pits are deep, irregular and scattered without any order rather than drawn out in rows. This pattern and the color of the ridges are what tell a “yellow” morel from a “black” one.

In young yellow morels the stem is also often barely visible. The cap sits low over the sand and is easily lost in the grass. All around is dry grass, last year's leaves and needles, and if it weren't for the pale spot on the dark sand, we'd have walked right past.

A mature common morel, on the other hand, can be a real giant. We found this one in spring in a broadleaf wood, among last year's leaves and fresh greenery. The cap is tall and egg-shaped, the ridges pale and wavy, and the stem thick and white, with an uneven, almost floury surface. Compare it with the photo above: the same type of pits, the same color, only twice the size.

The photo above clearly shows how deep its pits are and how the ridges twist and wind between them. Don't let this “waviness” put you off: these are still proper pits, open to the outside, and the cap clearly sits on the stem. The brain-like folds of a false morel look different, as you'll see a bit further down.

Cross-section: a single cavity from tip to base

The most reliable check, open to anyone with a knife, is to cut the mushroom open. Inside a true morel, black or yellow, you'll find one continuous cavity. Cap and stem are hollow together, like a single tube, with thin pale walls and no cottony stuffing, partitions or chambers. The photo shows a black morel cut in half: thin cream flesh under the ridged cap and an empty space in the middle.

Compare with the lookalikes:

• The false morel is not hollow in cross-section but divided into convoluted chambers and cavities, like a sponge with partitions.
• The early false morel and the thimble morel have a thimble-like cap attached to the stem only at the very top, with the lower edge hanging free. Their stem is often filled with a loose, cottony pith.
• In the morels this article is about, the cap is joined to the stem at its lower edge, and cap and stem share one cavity.

So here's a simple ritual we recommend: cut every mushroom in half lengthwise, in the forest or at least at home before it goes in the pot. You'll also see whether any insects have moved in.

Where we found them, and where you should look

As a general rule, “yellow” morels tend to grow under broadleaf trees: ash, poplar, elm, old apple trees, in orchards and along woodland edges. “Black” ones turn up more often in conifer and mixed forests, on disturbed ground, in felled areas, on bark mulch and especially after fires, where they can come up in great numbers the following spring. That said, some “black” species do grow under broadleaf trees, ash in particular.

Our finds break the pattern a little, and that's normal. Our black morel was in a broadleaf wood, among fallen oak leaves; the common morel grew on sandy soil among grass. The mushrooms clearly read the textbook less carefully than we did. So don't go by a single tree but by the whole picture: spring soil that has warmed up, a sunny spot, last year's litter, sand or loose soil, and also felled areas, old orchards and the verges of forest tracks.

One more thing: the dark caps of black morels blend almost perfectly into brown leaves. Found one? Stop and look around a few steps in every direction. Morels often grow scattered, several at a time.

The harvest: how to pick them and get them home

A good spring morel foray can fill your basket fast, and that's exactly when it's easiest to slip up. With a full basket, it's very easy to miss one false morel among a few dozen morels. A few habits that keep us safe:

1. Cut them with a knife at ground level rather than pulling them up. That keeps sand out of the pits and leaves the spot undamaged. More on this in the article cut or twist.
2. A basket, not a bag. Hollow mushrooms are fragile and quickly get crushed and sweaty in a bag.
3. Sort through every mushroom before cooking: look at the cap, cut it in half, check the cavity.
4. Don't take old, soft or moldy ones. A morel may be a delicacy, but it spoils quickly.

How not to confuse them with the false morel

We'll keep this short, since we covered it in detail in the article false morel: why this spring mushroom is dangerous.

• Cap. A morel has pits like honeycomb cells. A false morel has convoluted folds, like a brain or a walnut, with no regular pits.
• Cross-section. The morel has a single cavity. The false morel has chambers and partitions.
• Color. The false morel is usually chestnut brown to reddish, and its stem is short and thick.

False morels contain gyromitrin, which the body converts into monomethylhydrazine, damaging the liver, nervous system and blood. Boiling and drying reduce the amount of toxin but don't remove it: according to the Finnish Food Authority (2025), even after boiling twice, on average about a fifth of the toxin remains in the mushrooms, and no safe dose has been established. If you have doubts about even one mushroom, leave it in the forest.

How to cook them: boiled only

Both mushrooms are conditionally edible. Never eat them raw or undercooked: morels like that cause digestive upset. The best-known case was in 1991 in Vancouver, when 77 guests fell ill after a banquet salad containing raw morels. Exactly which substance is to blame still hasn't been pinned down, but it's known to break down with thorough heating. So first boil morels for at least 15 minutes, and only then fry, stew or add them to a sauce. We advise pouring off the cooking water: it's a standard precaution, though the long heating does most of the work. No “just fry them lightly” and no “add them raw to a salad”.

The second rule is moderation. French toxicologists reviewing calls to poison centers from 1976–2006 also described a neurological syndrome after eating morels: tremor, dizziness, a drunk feeling, an unsteady gait, sometimes visual disturbances. It set in on average 12 hours after the meal, occurred even after well-cooked mushrooms, and was more common in people who had eaten a lot of them. It usually passes on its own, although in some people the tremor lasted for weeks. So don't eat large portions of morels several days running, and if you're trying them for the first time, start with a small portion. Morels also dry well; more on that in the article how to dry mushrooms properly. General guidelines on boiling are collected in the cheat sheet how long to boil mushrooms.
