CEYLON POLYPORI. 
115 
— Favolus cucullatus Mont. 
Recorded by Cesati for Peradeniya from Beccari’s 
collection. Lloyd (Synopsis of the Genus Hexagona, 
p. 35) states that Beccari’s Ceylon collection at Kew is 
named by Cesati Favolus chartaceus, and is probably 
Hexagona cucullata. From Cesati’s description, suh F. 
cucullatus^ it would appear to be identical with the 
Ceylon species assigned to F. multiplex. 
The following list includes all the Polyporoids known to the 
writer to occur in Ceylon, either from herbarium specimens or 
recently-collected examples, with the exception of some 
species as yet unnamed, and others, Resupinati, recorded by 
Berkeley and Broome, which are based on undetermined 
mixtures, or which have not been recently collected and 
consequently cannot be redescribed. 
The prevalence of Polypori, or at least of those species 
which are saprophytic, in any country depends obviously on 
the quantity of fallen timber and decaying stumps available, 
provided that climatic conditions are favourable to their 
development. Over the south-western parts of Ceylon 
chmatic conditions are favourable almost throughout the year, 
and the drier northern and eastern regions have a rainy season 
of about three months, which suffices for the growth of a 
normal number. Fallen timber and old stumps are plentiful, 
at least in the wetter regions, with the consequence that 
specimens, if not species, of Polypori are abundant. 
When any great extension of planting occurs in Ceylon, 
large tracts of jungle are felled and burnt, a process which 
leaves tree trunks scattered in all directions, and countless 
huge stumps up to 4 feet in height over thousands of acres. 
Such conditions prevailed during the extension of rubber 
planting in 1905-1910, and it was possible then to gather 
cartloads of Polypori. Yet the nett results in such a case are 
disappointing, as comparatively few species colonize the logs 
which lie on the bare hillsides, exposed alternately to the 
scorching sun and the tropical rains. Vast numbers appear, 
_ but they are, as a rule, limited to a few species, and one grows 
weary of seeing Trametes ochroleuca, Trametes occidentalism 
Trametes Persoonii, Polyporus sanguineus, Lenzites repanda,
