Shaggy parasol vs parasol mushroom: how to tell them apart

The shaggy parasol differs from the parasol mushroom first and foremost by its stem and its cut flesh. The parasol mushroom has a tall, thin stem with brown bands that look like snakeskin, and its flesh stays white when cut. The shaggy parasol has a smooth, pale stem with no pattern, and its flesh quickly turns orange-red when cut, then browns. On top of that, the shaggy parasol is smaller and stockier, and the scales on its cap are coarse and curled up, like roof tiles.

We photographed both mushrooms this autumn: parasol mushrooms at the end of September in a pine and oak forest and in early October in a hornbeam and birch forest, and the shaggy parasol on 5 October among oak leaves. Below we go through them feature by feature.

Why it's worth telling them apart at all

The parasol mushroom is a good edible mushroom; its caps are fried like cutlets. A detailed portrait is in the article parasol mushroom, a giant worth knowing, and on what to call it properly, in the piece “zontyk” or “parasolka”.

With the shaggy parasol things aren't so simple. On our species page it is marked as conditionally edible: many people eat it without any trouble, but field guides warn that in some people it causes stomach upset. The British guide First Nature advises not picking it at all. So parasols that turn red when cut are worth recognizing and not mixing with parasol mushrooms in the same basket.

The shaggy parasol in our photos

We found this young shaggy parasol in an oak forest, right among the fallen leaves. The cap hasn't opened yet and looks like a ball covered in coarse brown scales. The scales are large, with their edges curled upward, and lie in rows like tiles on a roof. The stem is short, thick, smooth and white, browning slightly only at the top. There's no snakeskin pattern on it at all.

The photo at the top of the article clearly shows the proportions: the cap is massive, and the stem beneath it is a short white “stump”. In mature mushrooms the stem lengthens, but it still stays thicker than the parasol mushroom's: according to First Nature, about 2 cm in diameter versus 1–1.5 cm.

From above this mushroom has a smooth, dark brown crown, with the scales spreading out around it in rings. The farther from the center, the coarser and paler they get, with brown tips on a whitish, felty background.

The mushroom seems to sink into the oak litter. Unlike the parasol mushroom, the shaggy parasol is less fond of open clearings and more often found in shade: in forests of various kinds, and in places even in gardens on loose, humus-rich soil.

An honest confession: we didn't cut this mushroom, so there's no reddening in the photos. We identified it by its smooth, unpatterned stem and coarse, curled scales. If you find one like it, slice the stem lengthwise: the cut gives the most reliable answer.

The parasol mushroom in our photos

Now, for comparison, the parasol mushroom. At the end of September we came across several young ones in a pine and oak forest. Before the cap opens, a young parasol looks like a drumstick: a smooth brown “head” on a long stem. Its base is swollen, with soil stuck to the little bulb.

In the palm of a hand you can see the whole stem. It's much longer and thinner than the shaggy parasol's, and brown scales are already showing on it.

And here is the main feature of the parasol mushroom in close-up. The stem is covered in small brown scales that form crosswise bands — that same “snakeskin” pattern. On the egg-shaped cap the dark skin is already cracking into scales. Next to it lies a picked mushroom with a swollen base.

A mature parasol mushroom opens into a wide, flat cap on a tall stem, and you can spot it from far away. In this shot one stands deep in a clearing among oak leaves. That's a typical place for it: bright clearings, forest edges, grassy patches next to woodland.

In early October, in a hornbeam and birch forest, we found another young parasol mushroom. The cap has already spread a little, its scales are ragged, and the snakeskin pattern is clearly visible on the long stem. Compare it with the shaggy parasol's smooth white stem above.

From above, this parasol's cap is pale and creamy, with a brown center and smaller, ragged scales. The shaggy parasol's cap in our shot is much darker and coarser. But cap color in parasols is variable, so you can only take it into account; it's better to tell them apart by the stem and the cut.

Five features: how to tell the shaggy parasol from the parasol mushroom

1. Stem. The parasol mushroom's is tall and thin, with brown bands like snakeskin. The shaggy parasol's is smooth and whitish, browning with age and when touched, with no pattern. This is the most reliable field feature.
2. Cut. In the shaggy parasol the cut flesh turns pink, then orange-red, and then browns, most noticeably at the top of the stem. The gills turn red too if you bruise them. In the parasol mushroom the cap flesh is white and doesn't change noticeably.
3. Cap scales. In the shaggy parasol they're large, coarse and curled upward. In the parasol mushroom they're smaller and brownish on a pale background.
4. Size. The parasol mushroom really is bigger: according to First Nature, the cap is 10–25 cm and the stem up to 30 cm. The shaggy parasol is shorter, with a 5–15 cm cap and a shorter, thicker stem.
5. Habitat. The parasol mushroom loves light: clearings, forest edges, meadows. The shaggy parasol more often grows in the shade of the forest, and in places in gardens too.

But we wouldn't add the base of the stem to this list. It's often said that the shaggy parasol has an abrupt, rimmed bulb. But according to the MushroomExpert guide, such a rimmed bulb is typical of the closely related species *Chlorophyllum brunneum*, while in the shaggy parasol the base simply thickens gradually. The parasol mushroom has a swollen base too, so you can't tell them apart by the base.

Both have a white spore print, free white gills and a broad double ring that can eventually be slid along the stem. So the ring helps tell parasols from amanitas, but not parasols from each other.

Who else turns red, and why it matters

The parasol isn't the only mushroom that turns red when cut. The blusher also goes pink where it's damaged, but its cap carries greyish-white patches of veil, and its ring is thin, hanging and grooved. It's poisonous raw and is considered edible only after thorough cooking, so it must not be confused with a parasol.

The most dangerous moment is young, unopened mushrooms. While the cap is closed, a parasol is easier to confuse with amanitas, including the death cap. So always dig the mushroom up whole and check whether there's a sac-like volva at the base. First Nature advises not taking “parasols” with a cap under 10 cm, because they can be confused with small poisonous Lepiota species. Some of them are deadly, such as the deadly dapperling, which damages the liver.

There's also an exotic lookalike — *Chlorophyllum molybdites*, a poisonous parasol of the tropics and subtropics. Its main sign is a green spore print and greenish gills in old mushrooms. In 2020–2021 an Italian poison control center described ten poisonings by it in Sicily, with severe digestive upset. The GBIF database has no records of this mushroom from Ukraine, but it's useful to know about it if you forage in southern Europe.

If you do take parasols

• Cut every stem: flesh that turns red is a reason to set the mushroom aside separately.
• Don't take young closed “eggs” without clear features, or small parasols under 10 cm.
• Check the base for a volva, and the cap for patches of veil.
• Cook wild mushrooms for at least 15 minutes: that's what Germany's Federal Institute for Risk Assessment advises for any mushroom dish.
