substratum, septate, 2-3.5 f^ across; acervuli of couidial stage 

 (Gloeosporium) minutely tubercUlate, subepidermal, later erum- 

 pent, lisjjht pink in color; stromata disciform, brown ; conifliophores 

 densely seated on the stroma ; conidia oblon^-. frequently ovoid 

 ellipsoid or cuneate, often slii(htly curved, without guttulae or 1-2- 

 guttulate, colorless, light pink in mass, variable in size but chiefly 

 10-18 X 4-6 fi] perithecia subepidermal, black punctiform, solitary 

 or two together, globose or depressed-globose, slightly raised at the 

 apex with orbicular ostiola 17-20 fi wide, brown or brownish-blue. 

 100-150 IX in diam. ; asci numerous in one perithecium. fusoid, 

 broad at the middle, narrowed near the apex, wall often thickened 

 at the apex l)ut not stained by iodine, 46-60 x 8-13 /x, octosporous, 

 aparaphysate ; ascospores oblong, narrowed at both ends, usually 

 curved, hyaline, non-guttulate or guttulate, 10-15 ^ 3-5~S I'- 



On Cinnamomuui cainphora, infesting leaves, petioles, leaf-buds, 

 and young shoots in the nursery, causing considerable damage. 

 Old plants are also infected. Diseased spots are usually orbicular, 

 elliptical, or fusiform, 3-5 mm. in diam., first reddish-brown, later 

 becoming fuliginous, finally fading into light-brown. The infected 

 area is definitely marked from the healthy part, usually sunken, 

 and when severely affected the infected areas become confluent, 

 causing brown rot of the surrounding part, finally girdling the 

 stem and killing the entire plant.

Sawada states that the outbreak of the disease in the nursery and 

 young plantation of camphor trees near Taihoku caused much dam- 

 age in the spring of 1913. The Formosan fungus generally agrees 

 with that described from Kyushu l)y ^'oshino, with the exception
