with, perhaps, Polyporus gilvus and Pomes senex. Only when 
logs have been roUed into an uncleared ravine, under the 
shelter of the trees and shrubs, is an3rthing rarer to be found. 
Though our knowledge of the distribution of Ceylon Poly- 
pori is only in a preliminary state, it is clear that there are 
considerable differences in the distribution of the various 
species which can be, more or less, correlated with the varying 
climatic conditions in different regions of the Island. Some 
species occur in the wet low-country only, others have only 
been found at the top of the hills (5,000 to 7,000 feet), while 
others again prefer the dry low-country zone. 
Among the species which are generally distributed over the 
wet zone, from sea level to the hill tops, are Lenzites repanda, 
Polyporus gilvus, P. agariceus, P. Gaudichaudii, Pomes senex, 
P. caryophylli, and Trametes occidentalis. Pomes applanatus 
has the same range, and is common at 5,600 feet, but Pomes 
lucidus, though occurring at 5,600 feet, is distinctly rarer in 
these higher regions. 
Among the species apparently confined to the wet low- 
country we find Pomes dochmius, P. rhinocerotis, Trametes 
dubius, Polyporus rubidus, P. Didrichsenii ; but a large 
number of low-country species ascend to the elevation of 
Peradeniya, these latter including Polyporus ostreiformis, 
P. zonalis, P. durus, P. grammocepTialus, P. sanguineus, 
P. xanthopus, Pomes subresinosus, P. lignosus, P. hermes, 
Trametes odiroleuca, and the ubiquitous and polymorphic 
Trametes Persoonii. 
The up-country jungles, at 5,000 to 7,000 feet, have their own 
peculiar species in Polyporus elongatus, P. versicolor, P. anebus, 
P. ochroleucus, Pomes pectinatus, Dædalea subsulcata, and 
P. secernibilis, while P. dictyopus and P. setiporus, which are 
abundant there, descend to medium elevations. In the 
Hakgala Botanic Garden Trametes cervinus abounds, and 
Lenzites betulina and L. abietina occur, but in this locality 
European introductions are to be suspected ; Boletus luteus 
grows there in troops, and Collybia radicata has been found. 
The dry regions have not yet been worked with any approach 
to thoroughness, and we have very few records from them.
