Product Information

Collins Fungi Guide: The most complete field guide to the mushrooms & toadstools of Britain & Ireland 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. 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. Identification: Initially cup-shaped and smoothed, the fruiting body develops lobes in the shape of a wrinkled human ear. Soft, gelatinous and a date-brown colour, but when it dries it is much smaller, darker and harder. Upper surface is velvety, and is attached laterally by a small stalk. Up to 8cm across. Many species can only be distinguished with certainty by using a microscope to examine their spores and other microscopic structures, or by the application of specific chemicals to produce colour reactions. More technical monographs are needed for these.

Identification: One of the most iconic toadstools depicted in fairy-tale illustrations. It has a shiny, scarlet red or orange cap with white wart-like spots dotted across. Cap is 8-20 cm across. The gills are white and free, and the stem is swollen with rings of scales. 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. Where to find: Usually found low on the trunk of old, living oak trees and sweet chestnut trees, and sometimes on their stumps. Recommended Reading/Guides:Apply a streak across the cap of Agaricus species with a glass rod dipped in pure aniline and cross this with another rod dipped in concentrated nitric acid. A flame red colour at the point of intersection gives Schaeffer +; no red colour gives Schaeffer -. This test has been included in the Guide because it is useful for advanced study in the genus Agaricus, but concentrated nitric acid is an extremely dangerous chemical and the procedure should not be used by inexperienced collectors or those unfamiliar with the practices of laboratory chemistry.

For fungi an x20 magnification hand lens is useful. At some point the dedicated forayer will need a microscope, but that, as they say, is a whole new ball park. Or playing field, as they are also known. Identification: Are cup-shaped and scarlet, however can also be bright orange. Stems attach to the leaf litter making them appear as hollow bowls lying on the woodland floors. Cups are roughly 4cm across. This book allows everyone to identify mushrooms found in Britain and Ireland. The book is illustrated with beautiful photographs throughout, featuring the species you are most likely to see. Collect only specimens in good condition; old or rotten specimens will not make a good meal and can cause serious stomach upsets.

This fantastic guide is essential for foragers of all levels, from absolute beginners to the experienced fungi forager who would like to become an expert. Fungal nutrition is a complex subject but one aspect of it is nonetheless of particular importance in relation to their occurrence in the field. Anyone who has ever collected toadstools will have noted that many, perhaps most, occur in particular types of woodland, beneath particular types of tree or consistently in company with certain types of plant. This is not mere chance, nor the result of two species requiring a similar ecological niche. It is because of an intimate association called a mycorrhiza, which means that under certain circumstances the one cannot exist, or can do so only inadequately, without the other. A mycorrhiza is a symbiotic association between fungal hyphae and the roots of higher plants, and also, to some extent, of some Pteridophytes (ferns and their allies) and the rhizoids of Bryophytes (mosses and liverworts). The fungal mycelium forms an outer sheath around the fine rootlets and this can be seen if the rootlets are examined closely with a lens. Penetration of fungal hyphae into the root is limited and occurs only between the cells of the cortex. Precisely how the mycorrhizal mycelium assists its host plant, and vice versa, is still imperfectly understood, but it seems that the fungus obtains much of its necessary supply of carbon from the roots and, in return, acts as an intermediary in the uptake of nutrients such as nitrogen, phosphate and potash from the soil. The mycorrhizal fungus seems better able to achieve this uptake, especially from poor soils, than does the plant acting on its own.

These acids are extremely dangerous chemicals and should only be used by those experienced in their handling. Microscopic features The manifestations of a universal veil are somewhat different. Universal veils are not formed by all agarics but when present they envelop the entire developing ‘button’ and as the fruit body expands and matures, fragments of the veil remain as flakes on the cap surface, often in contrasting colour to the remainder of the cap. More significantly, however, the veil remains enveloping the base of the stem as a structure called a volva, the presence of which is characteristic of certain genera. The volva takes one of two main forms: when its tissues adhere closely to the stem base, it is called adherent and its surface may be loose and scaly, powdery or, sometimes, marked with characteristic concentric zones; when the volva envelops the stem base like a loose bag, it is said to be free and its tissues may then vary from very fragile to fairly tough and membranous.

Although the Law and its interpretation is rather complex, and no prosecutions have yet been brought, it is clear that deliberately and knowingly collecting magic mushrooms is illegal unless you intend immediately to destroy them or pass them to someone who is licensed to hold them. Licences are held by such bodies as the two Royal Botanic Gardens at Kew and Edinburgh but are unlikely to be issued to individuals. If you collect magic mushrooms without knowing what they are, it appears you will only commit an offence if you retain them once they have been identified. You will not be committing an offence of possession if magic mushrooms are growing uncultivated on your premises.Living organisms are given names and are classified into groups; fungi are no exception. The scientific names used for organisms today are based on a binomial or two-name system based on Latin and other languages and using Latin grammar derived from one devised by the Swedish biologist Linnaeus (Carl von Linné, 1707–1778). The binomial of each organism does more than signify its uniqueness, however, as it also attempts to indicate its relationship to other similar forms. Whilst each group of basically identical individuals is called a species, designated by the second of the two names, the larger groups to which similar species are considered to belong are called genera (singular genus) and it is the genera that contribute the first name. So, the fungus genus Lepiota includes species like Lepiota lilacea, Lepiota magnispora and Lepiota obscura. The specific or trivial name often attempts to give some information about the organism, for example lilacea signifies a lilac-coloured fungus and magnispora one with large spores, although sometimes, as in obscura, it does no more than recognise some undefined peculiar feature. This is the most comprehensive field guide to mushrooms ever published. With descriptions of over 3,000 species that can be identified with the naked eye, this book is all the reader will need to correctly identify any fungus.

Within these broad divisions, however, there is a wide range of environments. Broad-leaved woodland for instance embraces such disparate habitats as the almost pure stands of beech on the chalk downs with their extremely sparse ground flora, the rich oak wood with a ground flora dominated by early season species like blue-bells that flower before the canopy closes, and the carr, dominated by alder and willows and with almost permanent standing water. Copses and hedgerows are among several other more specialised types of woodland habitat. Each woodland type will be considered briefly in turn.Hbr S 10 Must Reads On Making Smart Decisions With Featured Article Before You Make That Big Decision By Daniel Kahneman Dan Lovallo And Olivier Sibony Shape. Cap shape shows the greatest difference between mature and immature specimens and this difference should be noted. The description of cap shape used normally in species descriptions relates to the mature form and five main types are recognised: bell-shaped, conical, convex (or in its extreme form, domed) with the appearance of an upturned bowl, flat and, finally, uplifted, where the entire cap is depressed into a bowl-like form with uplifted margins. In describing shape, the presence and form of any central bump or depression should also be noted. A cap with some form of central bump is called umbonate or, if the bump is very small and pimple-like, papillate; one with a depression is called depressed although a very deep depression rendering the cap funnel-shaped is found quite commonly and is characteristic of some genera. A depression in the cap with a small bump or pimple in the centre is also fairly common and is called umbilicate.
