The island of Juan Fernandez furnished to M. Bertero a good representative collection,[d] 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 concerned, as the aberrant forms are few."[e]
The fungi collected by the Antarctic Expedition in Auckland and Campbell's Islands, and in Fuegia and the Falklands,[f] were few and of but little interest, including such cosmopolitan forms as _Sphæria herbarum_ and _Cladosporium herbarum_, _Hirneola auricula-judæ_, _Polyporus versicolor_, _Eurotium herbariorum_, etc.
In New Zealand a large proportion have been found, and these may be taken to represent the general character of the fungi of the islands, which is of the type usually found in temperate regions.[g]
The fungi of Asia are so little known that no satisfactory conclusions can be drawn from our present incomplete knowledge. In India, the collections made by Dr. Hooker in his progress to the Sikkim Himalayas,[h] a few species obtained by M. Perottet in Pondicherry, and small collections from the Neilgherries,[i] are almost all that have been recorded. From these it may be concluded that elevations such as approximate a temperate climate are the most productive, and here European and North American genera, with closely allied species, have the preponderance. The number of _Agaricini_, for instance, is large, and amongst the twenty-eight subgenera into which the genus _Agaricus_ is divided, eight only are unrepresented. Casual specimens received from other parts of India afford evidence that here is a vast field unexplored, the forests and mountain slopes of which would doubtless afford an immense number of new and interesting forms.
