Sergipe and Amazonas are the smallest and biggest states of Brazil. The Amazone is famous because it is the richest biome for most terrestrial organism groups. Lichens are no exception, even though they are not very abundant in rainforest. Lichens are very species rich in the Amazon, and a single tree easily harbours 100 different species, and a small location up to 500 species. Also, many species grow on living leaves, easily up to 50 on a large, well-placed palm frond. In this book, some of these species are illustrated, in many cases for the first time, or for the first time in colour. New species Myriotrema psormuriforme Aptroot & Schumm, sp. nov Paraporpidia neotropica Aptroot & Schumm sp. nov New combination Fissurina bothynocarpa (Redinger) Aptroot & Schumm new comb. = Graphina bothynocarpa Redinger
The lichen genus Caloplaca is very diverse. Species are often colouring whole rock faces bright yellow or orange. This is the first book illustrating hundreds of species of this genus. From many species microscopic sections are illustrated, often for the first time. It includes all common species and many rarer ones. Of the most common species usually several specimens are illustrated to show the variation. This book is a resource for the identification of Caloplaca species.
