The same lemark niav e(|iially well apply to the present list 

 l)ut it is to be lioped tliat the hitter part ot" it may now be modified 

 considerably. One miiilit iiuh'ed at first wonder whether the Hevea 

 tree wonld urow at all niider the burden of siu-h a nunilier of un- 

 invited guests, and so far no other kind of tree in Malaya lias so 

 many fungi observed on it. It must be remembered however that 

 the chief reason so many fungi are here recorded is that so much 

 individual attention has been paid to the Hevea by Malayan my- 

 cologists. Tlu-re is no doubt that an equally large number of 

 fungi would be found on any other tree grown uinler similar con- 

 ditions and studied so assiduously and symjjathetically by experts. 



In the ])resent list tlie fungi are grouped according to their 

 res]K'ctive habitats. It will be seen that all parts of the tree carry 

 their (piota and that all the great groups of fungi are re)u\>i^ented. 



IJoor AND COLLAU. 



Follies lii/iii)siis„ Klotsch (J'olyjjoraceae). An orange coloured 

 Itracket fungus, [)robably the l)est known of rubber diseases. Pre- 

 viously, this fungus M'as known as F. seinitosfus, Saec. owing to a 

 wrong determination in the first instance. The first specimens in 

 Malav were collected by liidley in 1896 and forwarded to Kew. 

 (Considerable work lias been carried out in connection with it chieflv 

 by Gallagher and Bancroft, and is published in the bulletin of the 

 Department of Agriculture. Federated Malay States. 



Fomes ])xeudoferreus, Wakefield ( Poli/ijoracerw) . The "Wet 

 Eot" of Hevea, preTiously described under Poria lii//iolaterifia. 

 Investigated by Belgrave in 1!) 17-191 9. 



TI elicohasirlium , (?) //. nionipa, Tanaka (Tlielejiliomceae). 

 The specimens which were (ollected by Eidley in Selangor in 19U1 

 were sterile, and could not be definitelv determined. Massee con- 

 sidered them a species of Jfi'Iicohasidiiiin probably //. mompa 

 which is very destructive to the mulberry in .lapan. Xo further 

 collections of this fungus have been recorded. 



Ilyiiienocliaefe no.ria. Berk. {TheIe[ilioraceae) . A common 

 brown root disease. 



Irpe.r flavus, KlotSch. {II ijdnaceae). A bright yellow woody 

 fungus first collected on rubber by Eidley in 189T. Bancroft's 

 investigations are published in the bulletins of the Department of 

 Agriculture Federated Malav States. It is considered to !be 

 parastic. 



Mantsiiiiiis rotalis, B. et Br. (Agricaceae) . Bancroft re- 

 cords the mycelium of this fungus as oecuring at the base of trees, 

 like " horse hair." 



I^oria hypolateriin, Berk. (Polyporaceae) . Investigated by 

 Belgrave and orginallv determined as this species at Ceylon. Later 

 a re-determination has referred the specimens to Foines psiido- 

 ferreus. 



Ustulina zonafa, Sacc. {Sjdiaeriaceae). A black crustaccous 

 fungus which attacks the trees at their collar causing loss of foliage
