Abstract

Aimed at the non-specialist' hobby-botanist', this book does not claim completeness; about 74 of 100 European species of fern are illustrated, 228 mosses and liverworts, and 306 lichens. The photography is extremely pleasing. Friends who ask ' What do you see in lichens? ' will have this book placed in their hands, for picture after picture captures the texture, the colour, the design, which make the group aesthetically attractive. The printer is to be congratulated on the general standard of reproduction, the photographer on conveying both the quintessence of his subjects and their diagnostic details, and the author on a broad and representative choice of species. For the rest it is a pocket book, with conservative nomenclature, brief keys and a thumbnail sketch of each species mentioning its morphology, ecology, and the species or groups with which it may be confused. Macrolichens naturally predominate in the selection but a few of the more photogenic microlichens are included. The book covers central, northern and western Europe and forms a welcome addition to the European lichenologist's bookshelf.

“…The association has been described from vertical limestone surfaces on water tracks (Poland). The communities are transitional between Verrucariettea nigrescentis Wirth 1980 and Сollematettea cristati. In our opinion, the most typical to Peccanio coralloidisThyreetum pulvinatae is relevé 2 described by Nowak (Nowak, 1960: Table 16) because it includes the lowest number of diagnostic taxa from Verrucarietea nigrescentis.…”

“…The class Collematetea cristati includes few alliances. One of them is Peccanion coralloidis (Collematetalia cristati Wirth 1980) with Peccanio coralloidisThyreetum pulvinatae Nowak 1960(Nowak, 1960 as the type association (Bültmann et al, 2015).
