Appendix B. MR. BERKELEY ON HIMALAYAN FUNGI. 381 



The Diatomacesc consisted of: — 



Epithemia Broomeii, n. s. 

 therinalis, n. sp. 



Epithemia imequalis, n. sp. 

 Navicula Beliarensis, n. sp. 



The vegetation in the three sets of springs was very different. As 

 regards the Conferva, taking the word in its older sense, the species 

 in the three are quite different, and even in respect of genera there 

 is little identity, but amongst the Diatomacem there is no striking 

 difference, except in those of the Behar springs where three out 

 of the four did not occur elsewhere. In the Pugha and Momay 

 springs, the species were either identical with, or nearly allied 

 to those found in neighbouring localities, where the water did 

 not exceed the ordinary temperature. A longer examination will 

 doubtless detect more numerous forms, but those which appear 

 on a first examination are sure to give a pretty correct general 

 notion of the vegetation. The species are certainly less numerous 

 than I had expected, or than might be supposed from the 

 vegetation of those European hot springs which have been most 

 investigated. 



In conclusion, I shall beg to add a few words on the Fungi of the 

 Himalayas, so far as they have at present been investigated. As 

 regards these there is a marked difference, as might be anticipated 

 from the nature of the climates between those parts of Tibet inves- 

 tigated by Dr. Thomson, and the more southern regions. The fungi 

 found by Dr. Thomson were but few in number, and for the most 

 part of very ordinary forms, differing but little from the produce of 

 an European wood. Some, however, grow to a very large size, as for 

 instance, Polyporus fomentarius on poplars near Iskardo, exceeding in 

 dimensions anything which this species exhibits in Europe. A very 

 fine JEcidium also infests the fir trees {Abies Smithiana), a figure of 

 which has been given in the " Gardeners' Chronicle," 1852, p. 627, 

 under the name of JEcidium Thomsoni. This is allied to the Hexen- 

 besen of the German forests, but is a finer species and quite distinct. 

 JPolyporus oblectans, Geaster limbatus, Geaster mammosus, Erysiphe 

 iaurica, a Boletus infested with Sepedonium mycophilum, Scleroderma 

 verrucosum, an uiEcidium, and a JJromyces, both on Mulgedium Tata- 

 ricum, about half-a-dozen Agarics, one at an altitude of 16,000 feet 

 above the Nubra river, a Lycoperdon, and Morcliella semilibera, which
