10-Oct October's Olfactory Oasis

Summary

Step into the crisp October air and let your senses guide you. Beyond the visual beauty of autumn, this month offers a unique symphony of scents that transform the landscape. Forget the heady perfumes of summer; October unveils the "sweet smell of decay" in damp woodlands and the yeasty aroma of windfall fruits, reminiscent of Chaucer's beloved apples. Even in wild and cultivated gardens, subtle fragrances linger – from the spicy notes of winter savory to the musky allure of hoary plantain. But the true olfactory adventure lies beneath our feet, where wild fungi release an astonishing array of unexpected aromas. Prepare to be amazed by fungi smelling of peaches, garlic, old wine casks, or even a hot photocopier. Join us on an aromatic journey through October's hidden scents!

Scents

The air in October is said to be sweet, which is certainly true if you walk into a wood on a warm day, especially after it has just rained. Then that quintessential autumn scent referred to as “the sweet smell of decay” is all pervasive. Gone now are the thick heavy smells of winter plants as well as the highly floral and spicy scents of spring and summer.

Quite a number of flowers can still be seen across the landscape. However, they are largely bedraggled, possibly water-sodden or running to fruit and as such will be producing little or no scent. It is the yeasty smell of windfall apples and pears that is more likely to be noticed and Londoners even buy quinces Cydonia oblonga purely to enjoy their scent alone. Chaucer compared the scent of apples to sweet breath and it was believed to comfort tired minds.

Among the wild flowers still in bloom in October there are still a small number that are highly scented. On waste ground there is still plenty of yarrow, deadnettles and annual mercury. Others such as henbane and white horehound are now virtually extinct. Henbane with its famous smell of dead rats was thought to induce a coma-like sleep and a distilled liquid made from white horehound was used to cure coughs and said to have an “Eastern fragrance”.

Hoary plantain, still common enough on the North downs, was distilled to produce a popular musk-scented oil. However, in woods now there are far fewer flowers to enjoy except perhaps honeysuckle and on heaths there is always the ever present gorse.

Gardens, as you might expect, have a richer compliment of scents. October would have been a time in the past when many scented leaves were gathered to be dried and then used for nosegays, pot pourris or strewing herbs. Herb gardens were a particularly rich source of these leaves where winter savoury and one or two others would still be in flower.

The pungent smell produced by winter savoury’s dried leaves when trodden upon was said to rival both lavender and fennel. Elsewhere in gardens, climbers such as honeysuckle and jasmine flowers are still scented as well as some of the late repeat flowering roses. Geranium and pelargonium leaves still offer a range of spicy scents and Salvias an equally wide range of fruity scents. Among the shrubs Deutzia, Buddhlia and Ceanothus may also still be holding on to some fragrant flowers. Some of the smaller cyclamen have very light, sweet scents.

The increasingly popular New Zealand Cabbage Palm Cordyline australis may well still be in full flower. Its flowers are often too high up to enjoy their heavy, sweet smell but its ginger scented roots, eaten by the Maoris, are more accessible. The spicy scented roots of our own native Ploughman’s spikenard Inula conyza when it was more common would also have been dug up at this time of year and either been hung up or burned on fires to scent musty rooms, especially in ale-houses.

Putting flowers and roots to one side, the most interesting and unexpected scents of this month are to be found among the wild fungi. Most, when brought to our nose, have the typical mushroomy smell but other very common scents are flour, almond, musk, rancid and foetid. Mycologists, due I suspect to different nasal receptors or missing ones, disagree fiercely about the odours produced by some species but for most there is general agreement. Quite a number smell of particular fruit e.g. Russula amoena (peach), R. pectinatoides (stewed apple), Cantharellus cinereus (Mirabelle plum), Hygrophorus eburneus (mandarin peel) and chanterelles (apricot).

In others it is a particular vegetable e.g. Dermolona pseudocuneifolium (cucumber), Marasmius alliaceus (garlic), M. oreades (hay), and Micromphale foetidum (rotting cabbage). It is the more unusual and frankly bizarre fragrances that are worth seeking out. Unfortunately it may take several years attending quite a number of forays led by competent mycologists before you are lucky enough to be shown them. A selection of the more unusual in the London area would have to include Macrocystiden cucumis (cucumber and putty), Agrocybe cylindracea (old wine casks), Leptonia incana (caged mice), Tricholoma acerbum (hot photocopier) and Clitocybe hydrogramma (wet hen feathers).

Then there are the scents forgotten or lost in time such as Hygrophorus russo coriaceus ( Russian leather), H. cossus (goat moth) and Russula delica (bed bugs). There are also those that smell of gases e.g. Lepiota bucknallii (coal gas) and young Magpies Coprinus picaceus (naphthalene).

Even the unpleasant smells seem exaggerated in fungi e.g. Hygrocybe laetus (burning rubber), Camarophyllopsis foetens (dog faeces) as well as the notoriously foul smelling common and dog stinkhorns Phallus impudicus and Mifinus caninus. The opposite of these are the particularly attractive scents e.g. Lepista irana which is variously described as violets, orange blossom and even eau de cologne. More reliable are Hygrocybe russo coriaceus (sandlewood) and Russula lepida (cedar) the two scents so sought after by lovers of fine claret.
