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

Product Information

Finally, it should be noted if the gills are deliquescing or self-liquefying and turning inky, a characteristic of many species in the genera Coprinus, Coprinopsis, Coprinellus and Parasola. Many people come into mycology via a desire to try eating something a little more exotic than the shop bought mushroom. There are many edible species and they can have tastes and textures quite unlike the cultivated species. Hunting for edibles can be a wonderful experience but there are several rules to follow if your hunt is to have a happy outcome: The vital role of fungi in the ecology of grasslands is becoming more widely appreciated, sparking an increasing interest in identification. Mycology, or mushrooming, can appeal on many levels, from the simple pleasure of seeing strange and wonderful organisms to the intellectual challenge of trying to identify them and understand their intricate life cycles. But the starting point is, and always will be, a good book! And finally… hand lenses to help with mushroom identification

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.Note: we cannot stress strongly enough the caution with which you should approach mushroom identification. Some mushrooms are edible, but some are deadly, and identification can be very difficult. As Geoffrey Kibby says below, if in doubt, throw it out!). Dimensions. The length of the stem is measured from its point of emergence from the substrate to its attachment to the gills (which may be some distance from the cap surface if the gills are markedly decurrent). The diameter of the stem is a fairly variable character and difficult to measure accurately; but make note of a markedly stout or markedly thin stem (taking width in relation to length).

Fungi are not related to plants or animals because they differ from them in many important ways. Whereas the basic structural elements of plants and animals are cells which, en masse, form tissues, fungi are built up of uniquely different microscopic tubular thread-like bodies with multiple nuclei called hyphae; and collectively hyphae form, not tissue, but mycelium (although the word ‘cell’ is used widely in relation to small fungal structures that look like cells). The reproduction of fungi also differs greatly from plants in that they produce, not seeds, but microscopic structures called spores. 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 Add 8 ml concentrated sulphuric acid to 3 ml water and dissolve 1 g pure vanillin in this. A characteristic colour change occurs in some groups when this is applied to the stem. Concentrated sulphuric acid is an extremely dangerous chemical and the reagent must be prepared with the greatest care and only by those experienced in its use.

The sixth title in the bestselling Collins Guide series, this book covers the fungi of the British Isles, with considerable relevance for Europe and the wider temperate world. If you have permission to collect for scientific purposes do not abuse it by also collecting to eat.

A few types of Basidiomycete such as the jelly-like members of the family Dacrymycetaceae do not dry satisfactorily, and although they can be preserved in alcohol, formaldehyde or other liquid, the results are not very satisfactory. Most types of Ascomycete, apart from a few terrestrial species, are much less fleshy than most large Basidiomycetes and will dry very adequately in the air at room temperature. Identification An up-to-date, comprehensive and brilliantly illustrated book on fungi foraging in Britain and Europe. It covers every known edible species, and all the poisonous groups, as well as a few other extremely common ones. 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 Grasslands in Britain today are entirely artificial habitats, created largely in historical times on areas cleared of the ancient forest and used for grazing animals. Some grasslands are essentially short-term environments, lasting for one or a few years as breaks from other crops being grown in rotation on arable farmland. As habitats for macro-fungi, they are almost barren because no large basidiomycete has enough time to build up a mature mycelium in the soil before it is disturbed by ploughing. Such grasslands also tend to be subject, either directly or indirectly, to the fertilisers and crop-protection chemicals that form such an integral part of much modern farming and which do little to create a favourable environment for fungi. Apart from a few species such as Volvariella gloiocephala and Cyathus olla that grow on and among stubble, the modern farm field environment, with the exception of old set-aside land, will not repay much mycological study. 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.Geoffrey Kibby is one of Britain’s foremost experts on identifying mushrooms in the field and has published a range of excellent guides/handbooks to mushroom identification. To produce a spore print, use a fresh, mature but not over-ripe fruit body. The freshness is important because it can be difficult to obtain a print from specimens that have been kept in a fridge or allowed to dry out slightly. It is an operation that should be started immediately on returning home after a collecting expedition. Cut the cap from the stem at the apex with a sharp knife and place it gills downwards onto a piece of smooth, stiff white paper or card. Cover the cap with an inverted jar or similar cover and leave it undisturbed. Depending on the state of cap maturity, it may need to be left for anything between half an hour and 24 hours. The spores will then be discharged from the gills as described later and produce a pattern on the card; this is the spore print, and for most identification purposes the colour of the pattern on the paper, when dry, can be used. For critical genera like Russula, however, scrape the spores into a small heap with a microscope slide cover glass, flatten the heap gently with the cover glass and assess the colour of this mass of spores in daylight (take the card to a window during the daytime, because evening light in autumn and artificial light can give confusing colours). Chemical tests on the fruit body Dilute or concentrated solutions of hydrochloric, nitric or sulphuric acids. These acids are extremely dangerous chemicals and should only be used by those experienced in their handling. Microscopic features Heal Pelvic Pain The Proven Stretching Strengthening And Nutrition Program For Relieving Pain Incontinence I B S And Other Symptoms Without Surgery 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.
