Collins Fungi Guide: The most complete field guide to the mushrooms and toadstools of Britain & Ireland

Product Information

Always keep aside a specimen of anything you collect to eat and if it is a species you have not eaten before then sample just a little—even good edibles can cause upsets in some people (many people can’t eat strawberries or nuts for example). I bought this guide because I take photos of fungi during autumn and it is notoriously difficult to identify them. Other fungi books are limited in species so I could never be sure of a correct identification. Although practically everyone realises that the mushrooms they see in the supermarket are fungi, relatively few shoppers know how they fit into the overall scheme of living things, and how they are related to the fruit and vegetables nearby on the same shelf or to the animal carcasses on the butchery and fish counters. The truth is that mushrooms are not related to either, although there has been a tradition of teaching what little is taught about fungi in plant science rather than animal science courses – largely because, like plants, they often grow from the soil and do not move. It is now recognised, however, that living things can no longer be placed in two simple Kingdoms of plants and animals. Over the past fifty years, others have been added, and for some time Fungi have been referred to as the Fifth Kingdom, although some of the latest scientific thinking recognises six or even more to accommodate the wide range of microscopic organisms now known to exist. Nonetheless plants and animals are still the major groups with which most people are familiar. Always offer the results of your survey to the landowner or manager and explain the significance of what you have found.

Some fungi cannot be identified without a microscope, however those in this blog can be identified using macro characteristics displayed by the fruiting body. Most are umbrella or mushroom shaped with gills on the cap underside. Below are some key characteristics to look out for when identifying:Some of the woodland habitats discussed already, like birch woodland and alder carr, are essentially wetlands. Other habitats dominated by trees may present fungi with a moist, fairly uniform environment but they must adapt to poor aeration and the possibility of high concentrations of sulphurous gases. These are the conditions of bogs on acidic peaty soils, fens on less acidic peats and marshes on silty soils. Bogs may occur at both high and low altitudes, grading from moorland in the former where rainfall is high and drainage impeded. Fens occur typically in the upper parts of some old river estuaries but in all these habitats, mosses, especially species of Sphagnum, make up important components and it tends to be fungi that grow in close association with mosses that are the most characteristic species. Galerina, Pholiota and Hypholoma are among the genera of small, brownish and often inconspicuous Basidiomycetes found most frequently. Some of them have greatly elongated stems to facilitate spore dispersal clear of the Sphagnum or other vegetation. A very few Basidiomycetes like Arrhenia lobata that grow on and among the bases of rushes, sedges or other herbaceous plants may even be almost entirely aquatic. Dunes and salt marshes Dimensions. The diameter to be used is the average measured in centimetres across at least two diameters of a mature cap. The height, which is used normally only with markedly conical or bell-shaped caps, is the average in centimetres of at least two heights measured from the apex to the cap edge. Cap diameter and height vary considerably with overall growing conditions, and whilst there are obviously large and obviously small types of agaric, size alone is almost never a criterion for determining the limits of a species. Moreover, the size ranges given in the species descriptions should never be considered as excluding the existence of some particularly large or small individuals.

Spores and most other features of microscopic interest do retain their form more or less indefinitely and can be examined at leisure after small pieces of dried tissue have been macerated in warm water, Melzer’s reagent ( see here), methylene blue or cotton blue (see here). It should be remembered nonetheless, that for some fungi, such as those in the genera Lactarius and Russula, features like spore print colour, taste and smell are of such importance for identification that accurate naming of dried specimens without detailed notes on the fresh material is often impossible. Identification: Has a blue to violet tinged cap and gills when young, however older caps turn tan or grey from the centre. Gills are crowded and grow into the stalk and fade to brown as the mushroom matures. The cap is roughly 5-15 cm across, and the stem 5-10 cm tall.

The list of those species that are classed as magic mushrooms is only provisional and there is uncertainty about the validity of some of the chemistry on which it is based. Nonetheless, it does have legal standing. The relevant species are indicated in the text of this Guide. Equipment For collecting

Prepare Melzer’s reagent by adding 1.5 g iodine, 5 g potassium iodide and 100 g chloral hydrate to 100 ml of water. Warm carefully (do not boil) and stir thoroughly. When added to tissues or spores (especially white spores) en masse, a colour change to dark blue is called an amyloid response; a change to red-brown is dextrinoid; no change is non-amyloid and non-dextrinoid. At home, it is possible to begin a systematic examination of your specimens, but whilst numerous macroscopic features of the fruit bodies and microscopic details of their structure can be recorded, not all are needed to identify every fungus and each individual species description in this book uses only some of them therefore. The basis of this account is the identification of agarics which will comprise the bulk of the harvest from most collecting expeditions. Additional and different features needed for other groups are described here. Identification: A grey to fawn cap that is at first egg-shaped and then later bell shaped. The surface is smooth and splits into a few tiny scales from the apex, the edges are often wavy and split. Stem is white and hollow. Cap is around 4-8 cm across and stem is 5-15 cm tall.Collect only specimens in good condition; old or rotten specimens will not make a good meal and can cause serious stomach upsets. Shape. Most stems are equal (more or less parallel sided) but some taper either upwards or downwards; most species with rooting stems taper downwards into the ‘root’, while others are markedly club-shaped (clavate) with a highly pronounced taper upwards or even bulbous (with a pronounced swelling at the base like an onion). Some bulbous forms have a marked and rather sharp margin around the upper edge of the bulb; these are called marginate bulbous while those that swell very abruptly at the base are called abruptly bulbous. Stem shape in transverse section should be noted if it is other than circular; some species have markedly flattened or grooved stems for instance, while it is sometimes important to observe if it is solid in section, hollow or stuffed (apparently with a central hollow filled with cottony tissue).

There are an awful lot of fungi – 2,400 species in the latest field guide and that’s just the larger ones. Fortunately, perhaps, most of them are rarely seen. There are only about a hundred really common ones, and they are the ones you need to know.

Marginal characters. The margin of the cap may differ significantly from the remainder in colour or surface texture, and the edge may be either perfectly smooth (entire) or more or less wavy, split or eroded. There are often small radial lines around the circumference associated with the gill attachment but some caps are lined radially as a separate marginal feature. Remove the specimens carefully from the substrate, noting especially if the stem base is rooting (inserted deeply into the ground, rather like a carrot root). Make a record of any features that are immediately obvious and striking (a hairy cap, a smell of almonds or a bright red colour for example) and also those characters that change on handling (such as a colour change similar to bruising where the tissues have been touched, or an aroma that becomes suddenly apparent). Whenever possible, try to take at least one immature fruit body but remember that without some fully mature individuals identification will usually be impossible. It is much better to place only one collection in each container for bringing home; many toadstools look remarkably similar, especially when seen apart from their habitat, and trying to relate a mixed collection to one species can cause endless frustration. The need not to mix collections is even more important when collecting fungi to eat because an inedible or poisonous species can so easily be tossed into the pan along with the edible ones. Mushrooms is my personal take on the world of fungi in Britain, about the pleasures of searching for mushrooms and toadstools, and why they matter. I have written it as a narrative, in current TV parlance as a ‘journey’, beginning with the extraordinary diversity of fungi and the ways in which they exploit the natural world to the history of the fungus foray and the controversy over gathering wild mushrooms for the pot. In the process I zoom in on the nature of names, both Latin and English, at the places which hold the greatest diversity of fungi, and our attempts to conserve rare and vanishing fungi. It is, I hope, a refreshing and amusing look at this ‘third world’ of life, written without jargon and in lively style. I hope it can be read with pleasure by anyone. It is full of lovely colour photographs. A small range of chemical reagents will be necessary for use with particular groups of fungi, which cause characteristic colour changes when the chemicals are applied to them (either as macroscopic reactions, visible to the naked eye, or as microscopic effects, to be seen under the microscope). These reagents are shown here, along with details of the various tests. Collection and examination in the field
