Alb. and Schw., and Ag. Eookcri, Klot. belong to it, for the ring is very 

 evanescent. Ag. aureus occupies in the series Dermini the space between Lepiota 

 and Psalliota which would readily maintain the type of its subgenus (Togaria), 

 but I am unwilling to found a new subgenus from a single species. 



"Hypholoma partly answers to the Entolornata, and partly (section 

 Fascicularis) to the Flammulse. The FlammuL-e and the Fasiculares section of 

 of the Hypholomata are often confused. The Panseoli, moreover, should not be 

 in the second group, but in the third, since I should consider them analagous 

 with Naucoria and Psilccybe, because the stem is sub-cartilaginous, and the veil 

 is sometimes present, though sometimes searched for in vain — for example, on 

 comparison there is a clear analogy between Ag. foenisccii and Ag. papilionaceus. 



" I do not know whether you have seen my new work ' Iconea Hymeno- 

 mycetum.' I have sent to my dear friend Berkeley the figures of very many new 

 species.

" What Nylander and Hoffman (Op. p. 26) ca'l a trama in my viaw is not 

 a trama, but the base of the Hymenium. The trama according to my definition 

 is the Bubstanco of the pileus entering between the folds of the gills." 



3.— In the Gardener's Chronicle for September 2nd, 1870, the following 

 criticism was published, written by the Rev. M. J. Berkeley, author of the 

 standard work on British Fungology, and well known as the highest authority 

 in Britain on Mycological Science : — 



" Clavis Agaricinorum : an Analytical Key to the British Agaricini, with 

 Characters of the Genera and Subgenera. By Worthington G. Smith, 

 F.L.S. London: Reeve and Co., 1870. 8vo. Pp. 40, with six plates. 

 " This memoir was originally read before the Woolhope Club, Hereford, 

 Feb. 22, 1870, and we are glad that the author, who has done so much to illus- 

 trate the Fungi of this country, has thought fit to publish it separately, as it 

 undoubtedly must prove a great help to every student of an extremely difficult 

 tribe. We by no means assert, as some have done, that all difficulties are re- 

 moved, and that now nothing is easier than to determine any species of Agaric. 

 A line cf the old algebraic problem in verse — 



" He took it and tried, but it puzzled his prating, 

 would undoubtedly be the result if the critic went at once without any previous 

 knowledge to the determination of almost any species of Agaric. No doubt the 

 colour of the spores is a most important element in the distribution of Agarics 

 into subgenera, but even this will sometimes prove a difficulty, as anomalies 

 occur, and the tints are so very different in the Derrninum section. Lepiota 

 U confessedly very closely allied to Psalliota ; indeed in those species which 

 change their colour, and with the colour of the flesh at the same time that of 

 the spores, it is often impossible, from the inspection of dried specimens only,
