This series of books about the larger fungi of the British Isles is suitable for the dedicated amateur and the professional. Each volume provides keys to sections and species together with full descriptions of the taxa based on personal observations of the executive editors or, in the case of rare species, on authoritative descriptions of material. Many species are illustrated by line drawings. Colours are described using the accompanying Colour Identification Chart.

During the summer of 1980, the First International symposium on Arctic and Alpine Mycology (ISAM-I) was held at the then extant Naval Arctic Research Laboratory near Barrow, Alaska, U.S.A., well within the Arctic Circle (Laursen and Ammirati, Arctic and Alpine Mycology. The First International symposium on Arcto-Alpine Mycology. Univ. Wash. Press, 1982). The facility is currently owned and operated by the Utkeagvik Inupiat community and is named the National Academic and Research Laboratory, thus retaining its acronym NARL. Twenty-five scientists participated in that historic first meeting. Their interests in the fungi spanned a vast geographic area of cold dominated habitats in both the northern and southern hemispheres that included four continents (N. and S. America, Eurasia,and Antarctica), nine countries, and numerous islands ranging from Greenland to Jan Mayen in the Svalbard group. ISAM-I helped to develop ongoing interests and initiate others. This is what ISAM-I founders hoped would happen. Asa result, the organizing committee for ISAM-II was formed. Its mandate was to: involve a maximum of one third new participants in future ISAM meetings: divide the responsibility for organizing future meetings at sites located in areas of interest to research thrusts in Arctic and alpine environments: keep the number of participants small enough to ensure manageability, taking full advantage of field collecting opportunities with minimal complications and cost.

Periodic comprehensive overviews of the status of the diverse organisms that make up wildlife are essential to determining trends, threats and future prospects. Just over 25 years ago, leading authorities on different kinds of wildlife came together to prepare an assessment of their status of a wide range of organisms in Great Britain and Ireland in The Changing Flora and Fauna of Britain, also edited by Professor David L. Hawksworth CBE. Now, in The Changing Wildlife of Great Britain and Ireland, he has gathered together some of the original and also new contributors to review changes since that time and look to the future. Contributions range from viruses, diatoms, fungi, lichens, mites and nematodes; through butterflies, dragonflies, flies and slugs; to flowering plants, ferns, mammals, birds and fish. The state of knowledge in different groups is assessed, and the effectiveness of statutory and other measures taken to safeguard wildlife considered. The picture is far from bleak, ameliorating sulphur dioxide levels have benefited sensitive lichens and mosses in a dramatic way, water quality improvement has been beneficial, there have been few certain extinctions and rediscoveries of species thought to have been lost. Biodiversity Action Plans have also benefited targeted species, but habitat restoration and management for some is not always good for others. But there are worrying trends in declining populations, with an increasing number being regarded as threatened or endangered, especially in agricultural areas, and where woodland management has changed, particular threats from introduced species, and concern over the effects of climate change. Some of the smaller organisms remain poorly known, a situation unlikely to change as expertise in many is scant or being lost. This stock-check and look to the future will be a key source book to conservationists, naturalists, and professional biologists for many years to come.

This 1985 book describes research on the ecological, structural, physiological, genetic and molecular factors that control morphogenesis in the higher fungi. Both pure and applied studies of the biology of basidiomycetes are included in this volume, which provides a detailed synthesis of the area, by authors of the highest calibre.

The task of identifying mushrooms and toadstools has long been an overwhelming process. With over 3000 species found in Britain, field guides can add to the confusion. An Initial Guide to the Identification of Mushrooms and Toadstools is a must-have accompaniment to an up-to-date field book. Its easy to use keys follow a flow chart model which pose simple questions that can be read in conjunction with specimens. Even the most inexperienced of mushroom enthusiasts will find this process enjoyable and rewarding. This revised and updated third edition includes larger easier to read diagrams and text. Identifying mushrooms in the field has never been so easy.
