Mallotl's sp. {Kuphorhiaceae). 



Specimens in the Sintrapure herl)arium show leaves of this 

 plant as beinfr attacked by a species of S pliaerella (Sphaeriacecuie) 

 and Festalozzia' (Melancomaccae). Both fungi cause light hrown 

 circular spots on the leaves. 



M.vxoiFKitA JNDK'A, LiiiJi. { A iHicardiaceae) . Mango. 



Only three fungi have so far been definitely recorded on locally 

 grown trees for this species. GJoeosporium mangiferae Koack, 

 {MclanconiC'eac) which Bancroft describes as developing black sjwts 

 on the fruit. These sfpot.s increase in size and run together until 

 sometimes the whole surface is afPected, the pulp l)ecoming soft. 

 Baker found two leaf fungi, one the common black leaf mildew, 

 Meliola mangiferae, Earle, {Perisporiaceae) the other Zimmer- 

 manmella irispora, P. Henn. (Dothideaceae), occurring as raised 

 black knobs on the leaves. 



Maniiiot utilissima, Pohl. (Eupliorbiaceae). Tapioca. Cassava. 

 Bancroft records Cercospora Cearae, Fetch, (Dematiaceae) as 

 causing leaf spots on this plant, and also a curious occurrence of 

 Fovies Ugnosus on the tuberous roots, this latter fungus being ad- 

 mittedly a wood destroyer. 



MusA, sp.. {Scitamineae). Banana. 



The fact that only one fungus has been definitely recorded for 

 this ])lant in Malaya, is without doubt, only due to the fact that it 

 has so far not received much attention locally. Gloeosporium. 

 miisarum Cke. and Massee {Melanconiaceae) is included in Ban- 

 croft's list, as occurring on the ripe fruits. 



Nephelium lappaceum, Linn. (Sapindaceae) . Eambutan. 



A hlack mould, Meliola nepTreUi, Sacc. sp. nov. {Perispori- 

 aceae) was collected on the leaves of this species by Baker, at 

 .Singapore. It is rather surprising that hitherto no other fungi 

 have been recorded for this popular fruit, 



Oncosperma ftlamentosum, Blume (Pahnaceae). jSTibong. 



Bancroft quotes this as one of the jungle hosts of Fomes, 

 lignosus. 



Okmosia sumatrana, (Leguminosae). 



Baker collected specimens of Lemhosia hormosiana Sacc. sp. 

 nov. {Ili/.sferiaceae) on the leaves of this plant. 



Oeyza sativa, Linn. {Gramineae). Eice. 



Only one fungus disease can so far l)e found definitely recorded 

 for this important crop in Malaya. A smut, Uslilago virens Cke. 

 (Usfilaginaccae) is mentioned by Bancroft as being parasitic on 

 grains of rice in Perak.
