means by which any real advance would be made, and pointed 

 out various recent ideas on intensive description. Mr. Cotton 

 also has a short paper on the production of impoverished spores 

 by decapitated agarics. Other papers on Basidiomycetes are : — 

 " The Fruit-body Mechanism of Bolbitius," by Professor A. H. R. 

 Buller, in which it is shown that this genus stands far apart from 

 Coprinus ; " Some Notes on the Genera of the Thelephorese," 

 showing the origin of the present ideas on the group, by Miss 

 E. M. Wakefield, who also has a note " On the Identity of Corti- 

 ciuvi porosum Berk, et Curt," which is held to be identical with 

 the C. stramineum of Bresadola. Mr. F. T. Brooks records his 

 observations on pure cultures of certain Ascomycetes and 

 Basidiomycetes, the lignicolous species dealt with being grown 

 on sterilized blocks of wood. In the Uredineae, Mr. J. Eams- 

 bottom deals with the nomenclature of some of the species 

 according to the International Rules of Nomenclature. Mr. W. 

 Watson describes as new a Pyrenomycete, Pleospora hepaticola. 

 In the Discomycetes, Mr. Ramsbottom gives " Some Notes on the 

 History of the Classification of the Discomycetes," beginning 

 with Theophrastus and ending with the present systems ; and 

 " A List of the British species of Discomycetes arranged accord- 

 ing to Boudier's System, with a Key to the Genera." The names 

 given in Massee's " Fungus Flora " are appended. Dr. Bayliss 

 Elliott describes, diagnoses, and illustrates a new variety of 

 mould, Sepedonium mucorinum Harz var. botryoides. New records 

 for this country and new species to science are dealt with by Dr. 

 J. W. Elhs (" New British Fungi "), Miss A. Lorrain Smith and 

 Mr. J. Ramsbottom ("New or Rare Microfungi"), and Mr. Rea 

 (" New and Rare British Fungi "). The last paper is illustrated 

 by three plates, two of which are coloured, and are from drawings 

 by Mrs. Rea. The results obtained by cytologists in the study 

 of the reproductive processes of fungi during the past year are 

 dealt with by Mr. Ramsbottom. It will be seen that all branches 

 of the study receive attention in the Transactions, and both the 

 Society and their indefatigable secretary, Mr. Carleton Rea, are 

 to be congratulated on the appearance of a handsome number.

 Swart. Pp. 1-118, 5 Tafeln. 6 Mark. Jena: Gustav Fischer. 

 This interesting addition to the literature of vegetable 

 physiology begins with a general introduction of a couple of 

 pages, occupied chiefly with a discussion of previous conclusions, 

 such as those of Ebermayer (1876) concerning the behaviour of 

 various food-materials stored in the leaf in the autumn up to the 

 time of its fall. The opinion of the earlier students of this sub- 

 ject was that the food-materials in question travelled into the 

 stem, or perennating parts, when the deciduous leaves made their 

 preparations for fall. Wehmer's subsequent work (1892) and 

 criticism of this is mentioned, especially in regard to erroneous 

 deductions made from ash-analysis. The rest of the work is 

 divided into three parts. The first (pp. 4-69) deals with the
