This book focuses on two families of lichenized ascomycetes: Pyrenulaceae and Trypetheliaceae. It illustrated the majority of the accepted species in these families, which are most diverse on bark in tropical regions, most especially the Amazon. Fully updated dichotomous identification keys are given to all species in these families and to some similar groups and species, especially those in the same habitat, several of which are also illustrated in full. The illustrations are made from relatively recent material which still shows all characters, including gelatinous ascopore sheaths. For relatively recently described species, often type material is illustrated.

This book illustrates lichens that were recently collected in Alagoas state in Brazil. For many species, this is the first time that colour pictures are published. Full references to the descriptive literature and to synonyms are given. New species Staurolemma lineare Aptroot & Schumm

"The Lichen Flora of Great Britain and Ireland published in 1992 was an outstanding achievement for British Lichenology. It was a pioneering work and the first of its type in Europe. This much enlarged revision reflects the considerable accumulation of new information that has occurred since the publication of the first edition and is symptomatic of the enormous advances in lichen taxonomy over the last two decades. There are keys to 327 genera and 1873 species, which is an increase of 386 species since it was first published. The publication provides detailed information on morphology, chemistry and distribution for each species written in language that is readily accessible, avoiding obscure terminology. Both the glossary and introductory sections have been expanded and the latter includes helpful advice on the identification and examination of lichens. The preparation of this new treatment has involved a large number of contributors both in the UK and overseas and represents the culmination of lichen studies at this time. This book is undoubtedly the standard work for the identification of lichens in Great Britain and Ireland and will be indispensable to all serious students of British, Irish and overseas lichenology and other biologists working in related fields of ecology, pollution, chemical and environmental studies."--Publisher's description.

A comprehensive, up-to-date review of lichens as biomonitors of air pollution (bioindication, metal and radionuclide accumulation, biomarkers), and as monitors of environmental change (including global climate change and biodiversity loss) in a wide array of terrestrial habitats. Several methods for using lichens as biomonitors are described in a special section of the book.
