Leveille added 87 species, making a total of 246 species. . The 

 fungi of Sumatra, Borneo, and other islands are partly the same 

 and partly allied, but of a similar tropical character. 



The fungi of the island of Ceylon, collected by Gardner, 

 Thwaites, and Konig, were numerous. The Agarics comprise 

 302 species, closely resembling those of our own country.* It 

 is singular that every one of the subgenera of Fries is repre- 

 sented, though the number of species in one or two is greatly 

 predominant. Lepiota and Psalliota alone comprise one-third 

 of the species, while Pholiota offers only a single obscure species. 

 The enumeration recently published of the succeeding families 

 contains many species of interest. 



In Africa, the best explored country is Algeria, although 

 unfortunately the flora was never completed, f The correspon- 

 dence between the fungi of Algeria and European countries is 

 very striking, and the impression is not removed by the presence 

 of a few sub-tropical forms. It is probable that were the fungi 

 of Spain known the resemblance would be more complete. 



From the Cape of Good Hope and Natal collections have been 

 made by Zeyher,J Drege, and others, and from these we are 

 enabled to form a tolerable estimate of the mycologic flora. Of 

 the Hymenomycetes, the greater part belong to Agaricus ; there 

 are but four or five Polypori in Zeyher's collection, one of which 

 is protean. The Gasteromycetes are interesting, belonging to 

 many genera, and presenting two, Scoleciocarpus and Phellorinia, 

 which were founded upon specimens in this collection. Batarrea, 

 Tulostoma, and Mycenastrum are represented by European species. 

 There are also two species of Lycoperdon, and one of Podaxon. 

 Besides these, there is the curious Secotium Gueinzii. The genus 

 Geaster does not appear in the collection, nor Scleroderma. 

 Altogether the Cape flora is a peculiar one, and can scarcely be 

 compared with any other. 



At the most, only scattered and isolated specimens have been
