  Autumn crocus (meadow saffron)

  Colchicum autumnale

  Mistaken for

  Wild garlic — its leaves come up in spring in the same damp meadows and woodland edges.

  How to tell

  In spring, a stalkless tuft of a few broad, glossy, strap-like leaves wrapped round one another, often with a green seed pod in the middle, and no smell of garlic. Wild garlic leaves rise one by one on their own thin stalks and smell strongly of garlic. The pink, crocus-like flowers come in autumn with no leaves at all.

  What it does

  Colchicine: vomiting and diarrhoea 4 to 12 hours later, then failure of the heart, lungs, kidneys and bone marrow over the following days. There is no antidote, and foragers who ate it as wild garlic have died.

  Death cap

  Amanita phalloides

  Mistaken for

  Paddy straw mushrooms, young Agaricus, and anything picked as a 'field mushroom'.

  How to tell

  Greenish to olive cap with a faint metallic sheen, white gills, a ring, and a sac-like volva at the base. Introduced with European trees and now widespread, especially under oaks.

  What it does

  Responsible for most fatal mushroom poisonings worldwide. Half a cap can kill an adult; symptoms start only after the damage is done.

  Yew

  Taxus baccata

  Mistaken for

  Its sweet red arils look like berries, and it lines churchyards, parks and hedges where foragers pick spruce tips and juniper.

  How to tell

  Flat, dark green needles in two rows, plain green underneath with no white stripes, and red fleshy cups open at one end with a hard seed showing. No cones, no resin smell.

  What it does

  Taxine alkaloids stop the heart. The needles and the seed inside the red flesh are poisonous, there is no antidote, and about 50 g of needles can kill an adult.

  Thorn apple (Datura)

  Datura (the whole genus)

  Mistaken for

  Young plants come up among amaranth (morogo) and other wild greens in maize fields and gardens, and children eat the seeds.

  How to tell

  A coarse, rank-smelling plant with large, irregularly toothed leaves, big upright trumpet flowers, white or purple, and a spiny, walnut-sized capsule packed with small dark seeds. Amaranth has smooth-edged leaves and only bristly flower spikes.

  What it does

  Atropine and scopolamine: dry mouth, hot flushed skin, a racing heart, huge pupils, then delirium and hallucinations that can last a day or more. It has killed adults and children.

• Can kill

  Small parasols (Lepiota)

  Lepiota (the whole genus)

  Mistaken for

  Shaggy parasol and true parasol mushroom, which are larger relatives worth eating.

  How to tell

  The dangerous ones are small — a cap under about 8 cm — with brown scales on a pale ground and a ring. Size is the whole distinction, and it is not a comfortable one, so the safe rule is to leave every small scaly parasol alone.

  What it does

  Several small Lepiota species carry amatoxins and have killed adults. There is no benefit that justifies the risk.

  Ragworts and groundsels (Senecio)

  Senecio (the whole genus)

  Mistaken for

  Wild greens and herbal teas — and, in the past, home-grown wheat: Senecio in the flour poisoned whole families in South Africa's George district in 1918.

  How to tell

  Daisy-family plants with yellow flower heads (with or without petals), each head wrapped in a single row of narrow green bracts, often black-tipped, and seeds carrying white fluffy parachutes. A yellow daisy you can't name does not go in the pot.

  What it does

  Pyrrolizidine alkaloids, which baking does not destroy. They block the small veins of the liver (veno-occlusive disease): pain, a swollen liver and fluid in the belly, and in many cases cirrhosis. Children are the most vulnerable.

  Lily of the valley

  Convallaria majalis

  Mistaken for

  Ramps and wild garlic — it comes up in the same woods at the same time, with the same shape of leaf.

  How to tell

  Crush a leaf. Ramps smell unmistakably of onion and garlic; lily of the valley smells green and of nothing else. If it does not smell of onion, it is not a ramp. Ramps also have a reddish-purple stalk base.

  What it does

  Cardiac glycosides that disturb the heart's rhythm. Every part is toxic, including the water cut flowers have stood in.

  Brown roll-rim

  Paxillus involutus

  Mistaken for

  Assorted brown gilled mushrooms; it was eaten as an edible in Europe for generations.

  How to tell

  Inrolled felty cap margin, gills that bruise dark brown and can be rubbed off the cap, growing under birch.

  What it does

  Sensitises the immune system over repeated meals, then one day triggers it to destroy the eater's own red blood cells. People have died after eating it safely for years.

• Can kill

  Deadly galerina

  Galerina marginata

  Mistaken for

  Honey mushrooms, velvet shank, and sheathed woodtuft — all wood-growing clusters picked in autumn.

  How to tell

  Small brown cap on dead conifer wood, a ring on the stem, and a rusty-brown spore print. Honey mushroom drops a white print. Take a print before you cook anything you gathered off a log.

  What it does

  Carries the same amatoxins as the death cap in a far smaller body. A handful is enough.

  Euphorbias (milk bushes, naboom, pencil tree)

  Euphorbia (the whole genus)

  Mistaken for

  Prickly pear and other cacti — many African euphorbias are spiny, leafless succulents that look exactly like cacti — and the pencil-stick hedges of Euphorbia tirucalli around farms and villages.

  How to tell

  Break a stem: a euphorbia bleeds white milky latex at once. Cacti such as prickly pear bleed clear or slimy sap, and their spines grow from small fuzzy cushions; euphorbia spines grow singly or in pairs, never from a cushion.

  What it does

  The latex burns skin and mouth, and in the eye can cause temporary blindness. Wear gloves and eye protection near a cut plant, and never rub your eyes.

  Dwarf elder (danewort)

  Sambucus ebulus

  Mistaken for

  Elder — it carries the same flat white flower heads and black berries.

  How to tell

  Not a shrub: soft green stems 1–2 m (3–6 ft) tall that die back to the ground every winter, growing in dense patches from creeping roots, with leaves that smell foul when crushed and berry heads held upright. Elder is woody, with corky bark, and its ripe berry heads droop.

  What it does

  Every part is poisonous, the seeds especially: vomiting and diarrhoea.

• Hospital

  Sulphur tuft

  Hypholoma fasciculare

  Mistaken for

  Honey mushrooms and other autumn clusters on stumps.

  How to tell

  Sulphur-yellow to greenish gills and a bitter taste on the tip of the tongue. Honey mushroom has white to cream gills and a white spore print.

  What it does

  Prolonged vomiting; in quantity it has caused liver damage.

• Hospital

  Panther cap

  Amanita pantherina

  Mistaken for

  The blusher and other brown Amanitas some foragers eat.

  How to tell

  Brown cap with white warts, a ring, and a distinct rim at the top of the bulbous base. The blusher stains pink-red where damaged; this does not.

  What it does

  A stronger dose of the same compounds as fly agaric, with more hospital admissions and occasional deaths.

• Hospital13 records nearby

  Mediterranean jack-o’-lantern

  Omphalotus olearius

  Mistaken for

  Chanterelles, in southern Europe.

  How to tell

  Bright orange clusters growing from stumps and buried roots — especially of olive trees — with sharp, true, crowded gills running down the stem, and the same orange right through the flesh. A chanterelle grows singly from the soil, has blunt forking ridges, and is pale inside.

  What it does

  Illudin S: severe cramps, vomiting and diarrhoea. Not normally fatal.

• Hospital

  10 records nearby

  Pokeweed

  Phytolacca americana

  Mistaken for

  Its shoots are a traditional southern green, and the berries look like elderberries.

  How to tell

  Thick magenta stem and berries in a drooping raceme, each with a flattened top. Elderberries sit in a flat-topped cluster on green stems.

  What it does

  Roots, seeds and mature plant are toxic; the young shoots are eaten only after several changes of boiling water, and people are hospitalised every year for skipping that.

• Hospital

  7 records nearby

  Fly agaric

  Amanita muscaria

  Mistaken for

  Rarely mistaken once it is open — but the buttons, before the cap expands, look like white eggs and get picked as puffballs.

  How to tell

  Cut any 'puffball' in half. Solid white all the way through is a puffball; the outline of a cap, gills and stem inside is an Amanita button.

  What it does

  Ibotenic acid and muscimol: nausea, then confusion, agitation and deep sedation for several hours. Not usually fatal, but genuinely dangerous in children.

• Hospital

  4 records nearby

  Livid entoloma

  Entoloma sinuatum

  Mistaken for

  The miller, and aborted entoloma, which is eaten in eastern North America.

  How to tell

  Pink spore print and gills that turn salmon-pink with age, on a stout pale mushroom growing from soil under hardwoods.

  What it does

  One of the commonest causes of serious mushroom poisoning in Europe: hours of vomiting, and liver damage in quantity.

• Hospital3 records nearby

  Yellow stainer

  Agaricus xanthodermus

  Mistaken for

  Field, horse and wood mushrooms — about half the poisonings among people who gather Agaricus mushrooms are this one.

  How to tell

  Scratch the cap edge or cut the base of the stem: it turns an instant, bright chrome-yellow that later fades brown, and smells of ink or carbolic soap — more strongly as it cooks. Edible field and horse mushrooms smell pleasant and yellow only slowly and faintly, if at all.

  What it does

  Sweating, flushing, severe cramps, vomiting and diarrhoea. Some people eat it without trouble, which keeps its reputation muddled; it is banned from sale in Italy.

• Hospital3 records nearby

  Fibrecaps (Inocybe)

  Inocybe (the whole genus)

  Mistaken for

  Little brown and buff mushrooms picked in lawns, parks and woods by people after fairy ring champignons, St George’s mushroom or anything ‘meadow-ish’.

  How to tell

  Small brown or straw-coloured caps, often with a pointed centre and radiating fibres that split at the rim, gills turning grey-brown to snuff-brown, a brown spore print, and often a spermatic or green-corn smell. There are hundreds of species, separated only under a microscope — leave every one.

  What it does

  Many contain muscarine: sweating, salivation, tears, cramps, blurred vision and a slow heart within 15–30 minutes. Atropine reverses it; a large dose can stop breathing.

These are recorded within about 40 km of here in this month, from verified public observations. It is not a complete list of what is dangerous — nothing is — and a species missing from it may still be in your woods. Never eat anything identified from a photograph and a description alone.
