GEOGRAPHICAL DISTRIBUTION. 283 



Gardner in Brazil * Gaudichaud in Chili and Peru,f Gay in 

 Chili,} Blancbet in Bahia,§ Weddell in Brazil, || and Auguste 

 de Saint Hiliare IT in the same country. Small collections have 

 also been made in the extreme south. All these collections 

 contain coriaceous species of Polyporus, Favolus, and allied 

 genera, with Auricularini, together with such Ascomycetes as 

 Xylatia, and such forms of Peziza as P. tricholoma, P. Sindsii, 

 and P. macrotis. As yet we oannot form an estimate of the 

 extent or variety of the South American flora, which has fur- 

 nished the interesting genus Cyttaria, and may yet supply forms 

 unrecognized elsewhere. 



The island of Juan Fernandez furnished to M. Bertero a good 

 representative collection,** which is remarkable as containing 

 more than one-half its number of European species, and the rest 

 possessing rather the character of those of a temperate than a 

 sub-tropical region. 



Australasia has been partly explored, and the results embodied 

 in the Floras of Dr. Hooker and subsequent communications. 

 In a note to an enumeration of 235 species in 1872, the writer 

 observes that " many of them are either identical with European 

 species, or so nearly allied that with dried specimens only, 

 unaccompanied by notes or drawings, it is impossible to separate 

 them ; others are species which are almost universally found in 

 tropical or sub-tropical countries, while a few only are peculiar 

 to Australia, or are undescribed species, mostly of a tropical type. 

 The collections on the whole can scarcely be said to be of any 

 great interest, except so far as geographical distribution is con- 

 cerned, as the aberrant forms are few." ft
