Fly Agaric

Amanita muscaria

How to identify Fly Agaric

CapRed or sometimes orange in colour with white spots, which are remnants of the protective veil. They can sometimes be washed away by the rain.
Cap diameter10cm-20 cm when mature
GillsBegin white but become a pale yellow over time. The gills are free from the stem
StemWhite stems around 10cm-25cm long
SporesWhite

 

 

Where to find them?

Fly Agaric can be found in woodlands and along woodland edges. They often reoccur in the same place over multiple years and are widespread throughout Britain and Ireland.

Did you know?

The name Fly Agaric refers to the fungus having been used as an insecticide.

Don’t mistake it with?

If the white spots wash off the Fly agaric cap, it can be mistaken for red Russula species such as the Beechwood sickener Russula nobilis. There are also other Amanita species which look similar to the Fly Agaric but lack the distinctive red cap (e.g. The Blusher, Amanita rubescens)

About the Honey Fungus

The term Honey fungus actually refers to several closely related species, all within the Armillaria group. The two most common Honey fungus species are Armillaria mellea and Armillaria gallica, however there are a total of seven Honey fungus species found in the UK. These fungi are often well known by gardeners, as they can cause severe disease in trees and shrubs. 

As well as producing fruit bodies, Honey fungus forms distinctive bootlace-like structures called “rhizomorphs”. The tough leathery rhizomorphs are formed of bunches of fungal hyphae (root-like threads), and can commonly be seen underneath the bark of trees which have been infected with Honey fungus. Rhizomorphs vary from pale yellow and red, becoming brown or even black as they age. 

Where to find them?

Honey fungus grows in dense clusters on dead or dying wood, and can be found in woodlands, gardens, and parks. 

Don’t mistake it with

The different species of Honey fungus can be easily confused with each other. 

Did you know?

Armillaria mellea are bioluminescent, their gills glow in the dark! The glow from Honey fungus is very weak however, and is usually too faint to be seen by the naked eye in a woodland environment.

How to identify:

CapDeep purple, fading to lilac and sometimes white in dry weather
Size2cm – 7cm
GillsWidely spaced, and similar in colour to the cap
Stem5mm – 10mm in diameter and 5cm – 10cm tallIt is hollow, tough and fibrous, often twisted and sometimes flattened; deep purple at first, but becoming paler as the caps fade
SporesWhite

 

Where to find them?

Often occurring in large, crowded groups and usually found growing amongst leaf litter in coniferous or deciduous woods, commonly with Beech, Silver Birch or Oak.   

Don’t mistake it with

  • Older specimens with their pale caps are easily mistaken for the Deceiver Laccaria laccata, but the Amethyst Deceiver can be distinguished by the purple colouring that remains on the gills and the stipe
  • The Lilac Bonnet Mycena pura is another purple-lilac tinged mushroom, but has pale gills, more of a pink appearance, and the stem is not fibrous
  • The Lilac Fibrecap Inocybe geophylla var. lilacina is also similar, but is paler overall and does not have the purpley gills

Did you know?

The name ‘amethyst’ refers to the purple colouring of the young mushrooms and Laccaria means ‘lacquered’, referring to the shiny appearance of the fresh caps. 

Other Species

Chicken of the woods

Laetiporus sulphureus

How to identify:

BracketsThe fungus is comprised of several  overlapping brackets 
GillsThis bracket fungus does not have gills  
StemIt has no stem
FleshThick yellow-orange flesh which darkens with age. The underside of the brackets have yellow pores, which is the spore-forming surface of the fungus  
SporesWhite

 

Where to find them?

This fungus is a common find in woodlands across the UK. They are found mainly on deciduous trees, for example oak, sweet chestnut and beech. Often they are quite high up on the tree trunk, so its worth casting your eyes upwards!  

Did you know?

The flesh of this bracket fungus has a texture similar to cooked chicken, hence the common name!  

Don’t mistake it with…

The Giant polypore (Meripilus gigantus) can form similar bracket structures. However, the underside of Giant polypore turns black when damaged, which cannot be seen in Chicken of the Woods. 

Other Species

King Alfred’s cakes

Daldinia concentrica

How to identify:

CapNo cap, instead forms round shiny balls
Size2 – 8 cms 
GillsNo gills
StemNo stem
FleshStarts off reddish-brown and turns black. The flesh becomes brittle and charcoal like with age, and when cut in half, reveals distinctive concentric circles 
SporesBlack

 

Where to find them?

Find this fungus growing on dead or dying wood, particularly Ash and Beech.

Don’t mistake it with

There are many other fungi which produce tough black crusts on deadwood, however most of these produce much smaller fruit bodies than King Alfred’s Cakes.    

Did you know?

The common name of this fungus refers to its appearance resembling burnt cakes! As the story goes, a woman giving shelter to Alfred asked him to watch her cakes cooking. He let the cakes burn, and tried to hide the evidence by scattering them in the woodland.  

This fungus also makes a great firelighter! The fruit bodies can smoulder for a long time when lit, so may also have been used to transport a flame when on the move.

Where to find them?

This fungus grows in dense clusters on dead or dying wood, and can be found on deciduous or conifer trees.  

Don’t mistake it with

The Brick Tuft (Hypholoma lateritium) is very similar, but typically has a darker reddish cap, and its gills are more yellow rather than the green-ish tinge of Sulphur tuft gills. 

Did you know?

Sulphur tufts are bioluminescent, that is they glow in the dark! They don’t glow strongly, so the effect is best seen using a long camera exposure, or by shining the fruit bodies with a UV light.  

 

 

Other Species

Red Dead-nettle is traditionally known as the ‘bumblebee flower’ in some British counties as bumblebees love it! Other names include ‘sweet archangel’ and ‘bad man’s posies’. Red Dead-nettle is related to the stinging nettle but has no sting – hence the ‘dead’ in ‘dead-nettle’.

How to spot it

Red Dead-nettle has whorls of pink-purple flowers clustered amongst leaves towards the top of the plant. The aromatic leaves are hairy, heart-shaped and have toothed edges. Some leaves near the top of the plant take on a purple tint. This plant can be mistaken for henbit dead-nettle which has similar flowers. They can be differentiated because Red Dead-nettle leaves have short petioles (leaf stalks).

Where to spot it

Found throughout the UK, Red Dead-nettle likes arable and waste land and can also be found in gardens, hedgerows and on roadsides.

Best time to spot it

Red Dead-nettle has a long flowering season that can begin in February and last until November.

Things you might not know

  • The generic name is from the Greek lamia meaning ‘devouring monster’. This refers to the helmet shape (galeate) of the flower which has the appearance of open jaws.
  • The vernacular name ‘Archangel’ may refer to their virtue of being non-stinging.
  • It is likely that this plant was introduced to Britain with early agriculture and evidence for it has been found in Bronze Age deposits.
  • The whole plant is astringent, diaphoretic, diuretic, purgative and styptic. In terms of traditional medicinal uses, dried leaves have been used as a poultice to stem hemorrhaging whilst fresh bruised leaves have been applied to external wounds and cuts. The leaves are also made into a tea and drunk to promote perspiration and discharge from the kidneys in treating chills.

Habitat

A mature yew is compelling for its dense, dark evergreen foliage and buttressed trunk that has a colour close to mahogany.

Yew has a unique and remarkable association with churchyards where it was planted over graves to protect and purify the dead, and also for more mundane reasons such as being planted on a protected site to provide wood for long bows and to keep poisonous foliage out of reach of browsing cattle. It is also used for providing decoration for churches.

Where to spot it

Yew is concentrated in south-east and central England. It is primarily found in churchyards and woodland.

It is principally a species of well-drained chalk and limestone soils. In ancient woods it grows alongside ash, maple and beech.

Best time to spot it

The best time to spot Yew is over the winter, specifically in November, December and January.

Does Yew have any medicinal value?

It’s important to note that every part of the yew is poisonous except the flesh of its red berrylike fruit (the aril), although even that contains a toxic seed. The aril is slightly sweet which makes it tempting for children. Eating just a few seeds or a handful of leaves causes gastrointestinal problems, a dangerous drop in pulse rate and possible heart failure. Many victims are found dead and therefore are never able to describe their symptoms. Suicide by Yew was a way of avoiding defeat in Ceasar’s Gallic Wars.

However, Yews do contain an alkaloid named taxol which seems to be effective against ovarian, breast and lung cancers. Drug companies and research laboratories are offering to buy the foliage in bulk.

Things you might not know

  • Yew’s sticky red berries are popular with birds, and bird-sown seedlings can colonise open chalk downland as well.
  • In some parts of the UK you might hear Yew referred to as ‘Hampshire weed’ or ‘Snotty-gogs’ (for the berries).
  • The world’s oldest known wooden artefact is a 250,000-year-old yew-spear that was found at Clacton in Essex. The timber is so hard that it outlives iron.
  • The slow-growing yew can live two or three centuries but it is difficult to date mature trees because the dense wood does not always produce rings.
  • Yews are often pruned into formal hedges such as Hampton Court Palace’s famous 300-year-old hedge maze.

Other Species

String-of-sausages Lichen

Usnea articulata 

  • Grey-green tassels of up to 1 m hanging down or draped across the substrate but rarely anchored to it.  
  • Main stems have inflated sections which are pinched at intervals, and so resemble a string of sausages. This is a key feature to look for as there are other pendulous Usnea species but none have this characteristic.

Habitat

It is most common in the south west’s temperate rainforest zone. 

Favouring well-lit conditions and dry, open situations, it is most often found in tree canopies or on lower branches where trees are well-lit, in woodland or on scattered trees in open moorland. You can also find it on the ground after stormy weather. 

Similar species

Other large, bearded lichens include Usnea ceratina, Usnea dasopoga and Usnea hirta but these lack the sausage-like lobes. 

Did you know

  • It is a Section 41 species which means that it is considered of “principal importance for the conservation of biodiversity in England” under Section 41 of the Natural Environment and Rural Communities Act (2006).
  • A clean air indicator, rare outside of south-west England’s rainforest zone. Highly sensitive to sulphur dioxide pollution, it was once much more widespread in Britain but now appears to be making a comeback, perhaps due to improved air quality and a warming climate. 

Distribution 

Largely restricted to south-western parts of the UK with most records in south-west England.
