NOTICES OF NEW BOOKS. 



A Pocket Guide to British Ferns. By M. S. Ridley. London : David 



Bogue. 1881. 



Ferns seem to be the most popular of all "wild plants." People that 

 consider it beneath their dignity to look at any flower but a garden one, will 

 condescend to take, or affect, an interest in Ferns, if these are what they are 

 pleased to call " rare." Hence of the " writing of books." on Ferns " there 

 is no end. " This new candidate for the support of the Fern-loving public is 

 intended to afford to its readers a work which gives the distinctive specific 

 characters apart from the full description. While in most cases doing this 

 satisfactorily, it will, we think, also do good by teaching the reader how 

 niuch better it is to use technical botanical language (that is, words which 

 have a definite and precise meaning) than the slipshod style in which many 

 more pretentious works are written. It must at the same time be noted that 

 full explanation is given of every technical term that is employed. 



Illustrations of British Fungi. By M. C. Cooke. London and Edin- 

 burgh : Williams & Norgate. 



Those who are acquainted with Dr Cooke's ' Mycographia seu Icones 

 Fungorum,' will welcome 'Illustrations of British Fungi,' by the same 

 author, now in course of publication. The former work was confined to 

 Discomycetes. and contains illustrations of Morchella, Gyromytra, Helvella, 

 Verpa, Cidaris, Leotia, Mitrula, Spathularia, Geoglossum, Wynnea, and 

 Peziza. It contains 113 carefully executed plates, including 406 coloured 

 figures, with descriptive letterpress. 



The ' Illustrations ' now being issued contain figures of Hymenomycetes. 

 The work is intended to serve as an 'Atlas to the Handbook of British 

 Fungi.' Six numbers have been issued, containing 100 plates. In the case of 

 the smaller Agarics, a single plate will contain figures of more than one species.
