30 Book review
Continued from page 16
After 62 tntroductory pages, the rest of the
book is dedicated to the species account. Maps
are presented for all species, and show that
Baden-Wtrttemberg is one of the best investigated
areas in the world with respect to the
lichen flora. The generic delimitations are to a
large degree based on the central European
school of the last 15 years. For beginners, the
lecideoid genera are problematic, but this is
solved by keying all the genera in the Lecidea
key. In the text, the segregate genera are mostly
accepted, however, and one must look up under
Cecidonia, Porpidia, Tephromela, Miriquidica
and so on. The parmelioid lichens are treated

less consistently, i.e. by fully accepting some
genera hke Parmotremn and Parmeliopsis, while
other genera like Melanelia and Hypotrachyna
are treated as groups under Parmelia. This is
somewhat confusing.
The text in the species account is almost
identical to that in Flechtenflora by the same
author, and I use the latter book more frequently
because of its handbook size. It is especially the
excellent photographs that make Die Flechten
Baden-Wiirttembergs such an important work,
and I believe invaluable in its ability to arouse
interest for lichens among students and amateurs.
