magnificent herbarium, containing nearly 12,000 species, of which 
over 5,000 are type specimens, now deposited in the Kew Herbarium ; 
it is probable that his name will, in the future, be more associated 
with the morphological and physiological side of Mycology than as a 
systematist. 
The existence of basidia had been demonstrated before Berkeley’s 
time, but in an important paper, entitled, “On the fructification of 
the Pileate and Clavate tribes of Hymenomycetous Fungi” (Ann. 
Nat. Hist., vol. 1, 1838), Berkeley was the first to clearly indicate 
that basidia, usually bearing four spores, were universal throughout 
the group. At this date the fructification of the Gasteromycetes 
was entirely unknown, save through some investigations made by 
Berkeley, which were communicated to Montagne, the celebrated 
French Cryptogamist. The latter, quick to appreciate their true 
value, translated Berkeley’s correspondence, and it appeared under 
the title, “Sur la fructification des genres Lycoperdon, Phallus, et de 
quelques autres genres voisins” (Ann. Sci. Nat., Sept. 18 30). 
In this paper, accompanied by excellent figures, Berkeley de- 
monstrated the fact that basidia, bearing the spores, are equally 
characteristic of Hymenomycetes and Gasteromycetes, and thus 
established the natural group entitled Basidiomycetes. Next appeared 
a very important paper, entitled, “Observations, Botanical and 
Physiological on the Potato murrain” (Journ. Hort. BOG. 1. f. 9, 
1846). Berkeley was for some time editor of the Journal of the 
Horticultural Society, and during this period numerous important 
papers on plant diseases emanated from his pen. This especial phase 
of Mycology was continued in after years in the pages of “The 
Gardeners’ Chronicle,” where scores of brilliant articles on plant 
diseases caused by fungi testify to his thorough grasp of the subject, 
and secure for Berkeley the great honour of being the founder of the 
important science known to-day as Vegetable Pathology. In con- . 
clusion, Berkeley’s “Introduction to Cryptogamic Botany ” (1857), 
although superseded at the present day, contains numerous suggestive 
paragraphs, which are much more frequently utilised than acknow- 
ledgments would indicate by writers at the present day. 
Louis-René Tulasne, a member of the staff of the Natural History 
Museum, Paris, was a Mycologist of whom the French are justly 
proud. The following papers, selected at random from amongst 
numerous important contributions extending over a quarter of a 
century, suffice to indicate the calibre of mind possessed by the author. 
“Sur Porganisation et le mode de fructification des champignons de 
la tribes des Nidulariées ” (Ann. Sci. Nat., 1844). This paper illus- 
trates clearly for the first time the structure of the members consti-
