Mushroom and fungi identification can be tricky in the UK, but some that you’ll find are so distinctive that you won’t have any difficulties at all.
Mushrooms or toadstools – call them what you will – are the colourful manifestations of subterranean fungal webs or mycelia, which comprise the real engine room of our woods.
Some fungi are saprotrophic: they obtain their nutrients by breaking down organic remains. Others form mycorrhizal associations with trees or other plants: the mycelia bond with the root cells and thus ferry nutrients to the hosts. Up to 90 per cent of all plants are thought to have such fungal ‘helpers’.
Putting a name to the trees in a wood will tell you what fungi to expect. The magpie fungus occurs mainly in beechwoods, for example, while the sickener prefers pines and the larch bolete is (you’ve guessed it) a denizen of larch plantations.

Chanterelle mushroom Cantharellus cibarius
Chanterelle mushrooms can be found in coniferous and deciduous woods. Brilliant yellow; gills run part of way down thick stem. Edible (delicious).
Chanterelles are common and widespread in the UK.
Horn of plenty mushroom Craterellus cornucopioides
The horn of plenty mushroom is a woodland mushroom that favours deciduous woods and is often found in groups. Blackish, funnel-shaped or tubular cap with frilly edges.
They’re quite localised, but horn of plenty mushrooms are easy to see in some spots.
The sickener mushroom Russela emetic
Sickener mushrooms occur in pine woods. A ‘brittlegill’ with a scarlet cap and pure white gills and stem; gills break easily when touched. Poisonous.
Sickener mushrooms are common and widespread.
Charcoal burner mushroom Russell cyanoxantha
You can find charcoal burner mushrooms in deciduous woods. A ‘brittlegill’ with a lilac or red wine-coloured cap, often with olive tints.
Common and widespread in the UK, it shouldn’t be hard to find a charcoal burner mushroom.
Wood blewit mushroom Lepista nuda
Wood blewit mushrooms are found i deciduous woods and hedges. Rich tan cap; lilac stem and gills. Has a sweet, perfumed smell.
Like many other mushrooms here, wood blewit mushrooms are common and widespread in Britain.
Larch bolete mushroom Suillus grevillei
As you might guess from then name, larch bolete mushrooms are found under larches. Cap sticky, orange when young, yellower as it matures. Has pores instead of gills.
Larch boletes are localised but easy to see in the right spots.
Common stinkhorn mushroom Phallus impudicus
Common stinkhorn mushrooms aren’t particularly choosy and can be found in all kinds of woods. Cap covered in slime when fresh; releases foul smell to attract flies that spread its spores.
Given their non-choosy nature, it’s not surprising that common stinkhorns are common and widespread.
Hedgehog mushroom Hydnum repandum
Hedgehog mushrooms can be found in most woodland types. Cap creamy on upperside; underside has soft, pale spines (hence the name).
Hedgehog mushrooms are common and widespread.
Violet webcap mushroom Cortinarius violaceus
You’ll mainly find violet webcap mushrooms in birch woods. Big, beautiful mushroom with a rich violet cap; browns with age.
Violet webcap mushrooms are scarce and will generally require some thorough searching.
Verdigris roundhead mushroom Stropharia aeruginosa
Verdigris roundhead mushrooms occur in all types of woodland and also on heaths. Unique turquoise colour with white, fleecy patches when young. Poisonous.
Common and widespread, verdigris roundhead mushrooms shouldn’t be too tricky to find but are well worth searching out for their unique colour.
Magpie fungus Coprinus picaceus
You’ll find magpie fungus in deciduous woods, mainly beech. Bell-shaped cap with irregular white patches. Liquefies when old.
Magpie fungus doesn’t exist everywhere in the UK, but it’s easy to see in some spots in its localised distribution.
Yellow stagshorn fungus Calocera viscosa
Yellow stagshorn fungus can be found in coniferous woods, on rotten logs and stumps. Slimy when wet; when dry a deeper shade of orange.
Yellow stagshorn fungus is common and widespread.
HOW TO IDENTIFY MUSHROOMS AND FUNGI
- Join a fungi foray – it’s the best way to pick up ID tips. Many local conservation organisations organise forays on their reserves.
- Take spore prints from your fungi. Place the cap on a piece of clean paper, cover it overnight and next morning you should have a perfect spore print. Fungi fun!
- Specialise in a few fungal types, such as colourful waxcaps, coral fungi or boletes. Report unusual finds to your local records group; find a list here.
Correctly identifying fungi to species level is extremely difficult and many species are poisonous, and even fatal, so if you wish to forage fungi, we would advise doing so with an expert.
