This book brings together the results from over 2000 years of investigations into Greek lichens by workers from many countries. Greece has a rich lichen flora but it is not well known, in large part because previous publications are scattered through a wide, and often obscure, literature. This comprehensive and detailed checklist puts the study of Greek lichens onto a firm foundation, and will be indispensible for any botanist with an interest in Greece. Lichenologists throughout the Balkans and the eastern Mediterranean region will also find it of value.

Based on the acclaimed reference Lichens of North America, this resource for the classroom, field, and laboratory presents updated and expanded keys for the identification of over 2,000 species of lichens indigenous to the continent, twice the number covered by previous keys. The book includes a glossary illustrated with photographs by Sylvia Duran Sharnoff and Stephen Sharnoff and drawings by Susan Laurie-Bourque, all from the original book. The revised keys are an indispensable identification tool for botanists, students, scientists, and enthusiasts alike.--COVER.

This volume presents a revision of the Caloplaca saxicola group (Teloschistaceae, Ascomycetes) of the northern Hemisphere. The revision is based on the study of morphological and anatomical characteristics of approximately 650 specimens and their relevant type material. The specimens and type material studied are documented in drawings of microscopic structures and photos of thallus habit and apothecia. Furthermore the author presents a key to the taxa covered by this study. A statistical analysis was conducted to verify the significance of the spore characters for identification and completes this study. As a result of this revision, the following taxa are now part of the C. saxicola group: Caloplaca arnoldii (Wedd.) Zahlbr.; C. arnoldii subsp. clauzadeana Gaya; C. arnoldii subsp. nana Gaya; C. arnoldii subsp. obliterata Gaya; C. arnoldiiconfusa Gaya & Nav.-Ros.; C. biatorina (A. Massal.) J. Steiner; C. decipiens (Arnold) Blomb. & Forssell; C. pseudofulgensia Gaya & Nav.-Ros.; C. pusilla (A. Massal.) Zahlbr.; C. rouxii Gaya, Nav.-Ros. & Llimona; C. saxicola (Hoffm.) Nordin; and C. schistidii (Anzi) Zahlbr.

This volume focuses on the interaction of lichens with their substrate, environment and their biogeographic effects. In seventeen chapters thirty-eight authors present recent findings and developments in systematics, biodiversity, floristic studies and ecology, as well as newly described taxa, and keys to the identification of Caloplaca and xanthorioid lichens. Molecular phylogenetic analyses of several groups and genera are presented, resulting in an improved systematics of, for example, Caloplaca, Cladonia, Collema and xanthorioid lichens. The genera Arthonia and Usnea in Greece (with key) are reviewed. The volume is dedicated to Prof. Hans Martin Jahns on the occasion of his 70th birthday, featuring papers on some of his favourite fields of research, among them lichen interactions with their substrate and environment and lichen biogeography. A brief biography of Jahns, highlighting his contributions to lichenology, is included in the chapter on the nine Presidents of the International Association for Lichenology. Jahns played an important role during the past 40 years with his highly influential book, co-authored by Aino Henssen, entitled Lichenes. Eine Einführung in die Flechtenkunde. He is well-known for his extensive work and numerous publications on lichen morphology and ontogeny, particularly the development of fruiting bodies in different genera.

Not only an invaluable reference to what is known about lichen bionts and their interactions but also a guide to future studies. Compares various aspects of lichen-forming bionts with those of other fungi, algae and cyanobacteria. Features in-depth descriptions of culture methods. Includes over 1000 references representing a selective sampling in such subjects as air pollution, photosynthesis and respiration.

With well over 2000 species the Parmeliaceae is the largest family of lichenized fungi. Mexico with its huge topographic relief and wide range of habitats is one of the major biodiversity hot spots in the world. Accordingly, it is not surprising that this volume documents over 20% of the world's Parmeliaceae from this country. In fact a vast majority of the Parmeliaceae known from North America are covered in this volume. Descriptions (morphological and chemical), keys, distribution information and extensive specimen citations covering all states in Mexico are provided in the systematic treatments covering 450 species from Alectoria, Anzia, Bryoria, Bulbothrix, Canoparmelia, Cetraria, Cetrelia, Hypotrachyna, Flavoparmelia, Hypogymnia, Imshaugia, Kaernefelita, Letharia, Melanelixia, Melanohalea, Menegazzia, Montanelia, Myelochroa, Nodobryoria, Oropogon, Parmelia, Parmelina, Parmelinella, Parmeliopsis, Parmotrema, Parmotremopsis, Phacopsis, Protoparmelia, Pseudephebe, Pseudevernia, Pseudoparmelia, Punctelia, Relicina, Remototrachyna, Tuckermanella, Tuckermannopsis, Usnea, and Xanthoparmelia. Keys to genera are based on the most recent molecular data. All the species of Parmotrema known for North America are covered in the keys. The book begins with a review of the physiographic aspects and biodiversity of Mexico and proceeds to the first lichen community phylogenetic analysis for the major ecological communities in Mexico based on the Parmeliaceae. The book will be useful to anyone studying the lichens of Mexico as well as adjacent regions in Central America, the Caribbean, and the United States.

"This new edition of the universally acclaimed and widely used textbook on fungal biology has been completely rewritten, drawing directly on the authors' research and teaching experience. The text takes account of the rapid and exciting progress that has been made in the taxonomy, cell and molecular biology, biochemistry, pathology and ecology of the fungi. Features of taxonomic significance are integrated with natural functions, including their relevance to human affairs."--BOOK JACKET.
