In this report on the parasitic fungi on Pinus, Populus, and Quercus 

 in India, the diseases will be rated as follows: XXX-Dangerous, 

 XX-May be dangerous, X-Not dangerous. 



Pinus 



Six species of Pinus occur in the forests of India: (1) P. armandi 

 Frauchet, a Chinese pine, which occurs in northeastern parts of India, 

 (2) P. gerardiana Wall, ex Lamb, localized in NW. Himalayas, (3) 

 P. insularis Endl., in E. India, Upper Burma, and Philippines, (4) P. 

 merkusii Jungh & De Vr., a tropical pine in Far East, (5) P. vox- 

 burghii Sargent, and (6) P. ivallichiana Jack., the last two essentially 

 Himalayan. Diseases are known for only three of the species. They 

 'are as follows : 



1. Pinus insularis Endl. (Khasya pine). Eastern Distribu- 

 tion — Khasia and Naga hills, Manipur, Upper Burma a and Philip- 

 pines. 



Fomes pinicola Swartz. ex Fr. (XX) 



Attacks standing trees, causes brown cubical 

 rot. 

 Peridermium sp. (XX) 



The infection results in large woody out- 

 growths or galls on stem. The alternate host 

 of the rust is not yet known, but is believed 

 to be Quercus griffithi on which III develops. 



2. Pinus roxhurghii Sargent (Chir pine). Distribution : Outer 

 ranges of Himalayas, and on ridges of the Siwaliks flanking the 

 Himalayas, Bhutan in the east to Afganistan in the west. 



Oapnodium pint Berk, and Curt. (X) 



Coleosporium campanulae (Pers.) Lev. (X) 



A heteroecious needle rust, and I on needles 

 of chir, II and III on Campanula colorata 

 Wall. 

 Cronartium Mmalayense Bagehee (XXX) 



A heteroecious stem rust, and I on 3 needle 

 chir pine, II and III in Sioertia spp. 

 Fames annosus (Fr.) Cke. (XX) 



Fomes pint (Thore) Lloyd (XX) 



Fomes pinicola Swartz. ex Fr. (XX) 



Attacks standing trees, causes brown cubical 

 rot. 

 Ganoderma applanatum (Pers.) Pat. (X) 



Ganoderma lucidum (Leyss.) Karst. (X) 



Lophodermium pinastri (Schrad.) Chev. (X) 



Causes needle cast. 

 Pestalotia funerea Desm. (X) 



On needles. 

 Polyporus schweinitzii Fr. (X) 



Causes brown cubical rot in butt portions. 

 Septoria pisi Berk. (X) 



Causes leaf spot. 



3. Pinus wallichiana Jackson (blue pine). Distribution: 

 Throughout temperate region of the Himalayas, chiefly at 6,000-
