354 EXPERIMENT STATION EECOBD. [Vol.35 



A new Cylindrosporium, M. Txtrconi {Atti 1st. Bot. R. Univ. Pavia, 2. ser., 

 9 (1911), pp. 28-30). — C. pollacd n. sp. is the name given to a fungus parasitic 

 on Ilex furcata. 



The hydropsy of Madake (Phyllostachys bambusoides), S. Kawamuba 

 (Extracts from Bui. Forest Expt. Sta., Tokyo, 1915, pp. 127-130, figs. 4).— 

 Madake has recently been increasingly afEected with a disease characterized 

 by accumulations of water in the stem, especially the middle portions, but not 

 in the uppermost internodes. The leaves gradually fall and the stem becomes 

 weak and unfit for use. The symptoms and their alterations are described in 

 some detail. The cause of the trouble has not been determined. 



The red plague of Sugi (Cryptomeria japonica) seedlings, S. KLawamuba 

 (Extracts from Bui. Forest Expt. Sta., Tokyo, 1915, pp. 131-133, fig. 1). — It is 

 stated that since the red plague of Sugi became known a few years ago in 

 Japan, the trouble has spread until it has now been reported from various 

 parts of the country. The symptoms of the disease are described. 



The author's investigations since 1911 have led to the conclusion that the 

 disease attacks only this plant and is confined to seedlings under five years 

 of age. Of the three fungi noted in this connection, Pestalozzia appears to be 

 usually associated with other fungi, mostly on old, decayed leaves, and Cerco- 

 spora is still under investigation, so that this report is confined chiefly to a 

 discussion of Phyllosticta. The fungus attacks first the lower and then the 

 higher leaves, causing discoloration, and later the twigs, causing dark brown 

 spots on the surface, and eventually killing the leaves, causing complete failure 

 of growth. 



A disease of immortel trees, J. B. Robek (Bui. Dept. Ayr. Trinidad and 

 Tobago, H (1915), No. 4, pp. 128, 129). — A disease affecting Erythrina velutina 

 is described, in which the leaves show first a pale green, then a yellow color. 

 This is followed by a dieback, the branches falling away gradually and the 

 bare, dead trunk finally rotting and falling to the ground. This occurs in 

 widely separated groups of from 10 to 20 or more trees. Often, though not 

 always, the cacao trees under the dying immortel trees are affected in much the 

 same manner. The trouble may be connected with insufficient drainage. No 

 parasites have yet been shown to produce the disease, and the symptoms suggest 

 root trouble, poor soil conditions, or bad water relations. Deep and thorough 

 drainage appears to be the best means of control. 



Hypoderma deformans, an undescribed needle fungus of the western yel- 

 low pine, J. R. Weib (C7. S. Dept. Ayr., Jour. Ayr. Research, 6 (1916), No. 8, 

 pp. 277-288, pi. 1, figs. 4). — A technical description is given of H. deformans 

 n. sp., which is said to cause a serious needle disease of the western yellow 

 pine (Pinus ponderosa) in parts of Idaho, Washington, and Montana. 



The fungus is said to be a true parasite, attacking the foliage of all age 

 classes. The first sign of infection is usually a slight browning of the tips of 

 the needles, or, in regions of heavy infection, the entire needle may assume 

 a straw yellow color deepening to a brown on the first appearance of the 

 apothecia. The terminal shoots do not attain their normal development, and 

 witches' brooms are frequently produced. 



The author considers this fungus a possible cause of disease in nurseries, 

 although, up to the present time, it has not been found in the forest tree 

 nursery. Cutting out and burning the infected parts or trees are recommended 

 as means of control.
