In October Mr. Henderson visited Tasek Bera, Pahang, in company 
with Mr. W. Birtwistle, Officer-in-charge, Fisheries Department. The 
District Officer, Temerloh, kindly arranged to supply launches and boats. 
Results were disappointing as regards the number of specimens collected, 
but some interesting ecological observations were made. 
Mr. E. j. H. Corner made two expeditions during the year, to collect 
fungi, chiefly Basidiomycetes. From June 23rd to July 8th, Mr. Corner 
visited Negri Sembilan with Dr. G. A. C. Herklots, of Hong Kong 
University, and collected in the forest reserves round Kuala Pilah and 
Jelebu and on Gunong Angsi. Thanks are due to the District Forest 
Officer, Kuala Pilah, for the service of two forest guards during the stay in 
that neighbourhood, and to the Resident, Negri Sembilan. for permission to 
occupy the bungalow on Gunong Angsi. Special attention was given to 
fungi parasitic 011 the larger trees. Fomes setulosus Fetch was seen 
commonly on the large dipterocarp trees, usually at a considerable height 
above the ground, and Fomes pachyphlceus Pat. was found on Dialium sp. 
in three localities. No basidiomycetes were found, however, on the 
numetous trees of Dainar Minyak (A gat his alba) both living and dead, 
which were examined on Gunong Angsi, and the wood of this species seems 
exceptionally resistant to decomposition by fungi. A large variety of 
wood-destroying fungi were collected on the standing and fallen trunks of 
the Class II trees which had purposely been killed by ringing. A striking 
feature on Gunong Angsi was the great number of true mushrooms 
(Psalliota spp) which were developing in clusters through the jungle: some 
of these were tried at the table but they proved very unpalatable. About 
330 collections of fungi were made. 
f rom 2nd November to the 7th December an expedition was made by 
Mr. Corner to Tembeling, and thanks are due to Mr. C. E. Carr, of 
1 embeling, for his hospitality and assistance in making local excursions. 
Fraser’s Hill, Sungei Cheka and Kota Glanggi were also visited from 
Tembeling. On account of the large number of forest trees killed by the 
floods in 1926 to 1927 the lowland jungle was extraordinarily rich in wood- 
destroying fungi. About 800 collections of fungi w r ere made, comprising 
some 600 species, and three quarters of these were gathered from the rotting 
timber. Of special interest were numerous fructifications of Fomes 
sctidosus and Ganoderma sp. found parasitic on large jungle trees by the 
Sungei Cheka and the discovery of 9 or 10 species of Gcaster growing in 
troops on the forest floor. F. pachyphlocus was found parasitic on Ficus 
sp., F. pectinatus Klotz on Irvingia malayana, and Ganoderma {Fomes) 
applanation on a flood damaged rubber tree. Fomes rimosus Berk, and 
F . kermes Berk were very common on the fallen timber, 
A good deal of local collecting was also done by Mr. Corner in Singa¬ 
pore and numerous observations have been made on the seasonal appearance 
and the rates of development of certain fungi. Several short excursions 
were made also to Gunong Panti in joliore; and to neighbouring islands 
with Mr. W. Birtwistle, Officer-in-charge, Fisheries Department, for the 
purpose of collecting algae. 
HERBARIUM WORK AND OTFIER INVESTIGATIONS 
ddie reconstructed Herbarium building was completed in January 1930. 
The general herbarium of flowering plants was arranged in 7 uniform double 
ranks of cases (in all 84 two-unit teak cases) on the ground floor. The * 
remaining floor space is occupied with sorting tables, storage cases, etc. The 
gallery holds the herbarium of cultivated plants, museum specimens and 
spirit collection. The extensive collection of timber specimens w T as handed 
over to the Forest Research Institute during the year. 
Routine work in the herbarium continued as usual. All 1929 collection 
of flowering* plants (amounting to about 2,000 numbers) w r ere dealt with 
except the families which are in the hands of specialists at Buitenzorg. A 
number of new' species in these collections will need further study. About
