ON THE SO-CALLED TIGER’S MILK. 343 
the mountains and at the roots of tall trees. He compares it 
with the Chinese plant now called Fuhling (Pachyma Cocos). 
This is a well known Chinese drug ofa very similar nature 
to our Tiger’s Milk, and which is probably also the same as 
the Tuckahee or Indian Bread of North America. I obtained 
a specimen of the Chinese Fuhling in the Singapore market. 
It is sold in the drug shops, and appears to have some repu- 
tation as a medecine. The plant differs somewhat from the 
Susu Rimau, and [ should imagine is a different species. It 
is more regular in shape, resembling a large truffle externally 
with a cracked brown skin darker coloured than that of the 
Tiger's Milk. The interior is a little more mealy in texture, 
but perhaps this is due to the age of the specimen, and the rind 
is thicker. In section the microscope shows that there are 
the fungus threads asin the Susu Rimau, but that the glo- 
bose cells are represented in great measure by amorphous 
granular masses. The white substance of Pachyma is stated by 
Professor BERKELEY to consist of masses of pectine traversed 
by mycelium threads, and the whole thing to be of the nature 
of a sclerotium, that is to say, a fungus in a restingstate. Mr. 
G. MURRAY, in a paper read before the Linnean Society in 
1886, described a sclerotium upon which a Lentinus was 
growing somewhat as in RUMPHIUS’ picture which was 
brought from Samoa in the Fiji Islands by Mr. WHITMEE, 
This he thought at first might be identical with the Pachyma. 
Microscopic examination, how ever, showed no pectine in the 
Samoan plant, which consisted merely of a mass of fungus 
threads, and in fact was a typical Sclerotium. 
Our plant i is, however, somewhat more than this, as the pro- 
portion of fungus threads to the white globose ceils is so very 
small. It is evidently more closely allied to Pachyma, but | 
think is quite distinct from that specifically and may indee 
be RUMPHIUS’ long-lost Tuber Regium. 
The Bukit Mandai mass was partially encrusting a piece of 
rotten timber, and from it apparently grew a stalked Polypo- 
rus of large size. I thought at first that I had got hold ot the 
fungus that produced the Susu Rimau, and was much surprised 
to find it was a Polyporus, and not a Lentinus, but a section
