In British Basidiomycetae (Cambridge University Press, 30s. net), Mr. Carleton
Rea has given us what will be the standard handbook to the larger British fungi—mushrooms and toad- stools. The different kinds that bad been found in Britain have been described on former occasions, but in such a large and difficult group new forms are being discovered each year, and this fact and recent modifications in nomenclature and arrange- ment, brought about by our increased knowledge of these plants, have rendered a new account desirable. Mr. Rea, in the volume before us, has brought his thirty years' study of the group to the task of presenting this newer knowledge. Mr. Rea is well known as an authority on the Be.sidiomyceirs, and his work, published under the auspices of the British Mycological Society, can be confidently recommended to those readers who are interested in these plants.
