 Hist. Soc.) 4 15 : 4-5. T. 3, v, May, 1914. (Japanese.) 



Ovary infesting, appearing in group on the ear of the host plant, 

 dark olive in color, balloon- or top-shaped, rounded at the apex, 

 3 mm. long, first covered by a membrane, later rupturing at ma- 

 turity, exposing the dark-olive spore mass inside, lower part of the 

 mass being associated with glume and palea, hard, sclerotium-like, 

 inside of the mass white or very light straw-color, composed of 

 closely arranged angular cells ; spores globose or ovoid, covered 

 with comparatively large-sized warts, dark-olive, 4-5.5 usually 

 4-5-5 /*• 



Parasitic on Saccharum narenga. 



Type locality : Akocho Hanshoryo Keishusho, Formosa, Dec. 

 10, 1907. (Y. Shimada.) 



The cross-section of the sclerotium-like body is entirely paren- 

 chymatous, and no parallel hyphae are visible as in the case of 

 Ustilaginoidea Oryzae Bref. 



Plasmopara Wildemaniana P. Henn. var. macrospora K. 

 Sawada var. nov. in Taiwan Hakubutsu Gakkwai Kwaiho 

 (Journ. Formosan Nat. Hist. Soc.) no. 16: 2-4. T. 3, vii, July, 

 1914. (Japanese.) 



Foliicolous ; spots irregular, often occupying the entire leaf, light 

 yellowish-green, white mouldy on the lower surface; hyphae in 

 mesophyl intercellular, invading the cell only by haustorium, color- 

 less, continuous, branching, 7-13 n thick; haustoria globose or 

 ovoid-globose, 13-17 x 9-18 /x,; conidiophores fascicled from the 

 stoma, upright, 320-605 ^ long, main axis 8-12 /x thick, slightly 

 swollen at the base, first branching at about one half or one third 

 of the whole length from the base, usually branching 5 to 7 times, 

 terminal branchlets (commonly 4-8 /jl long) and their underlying 

 branchlets very short; conidia ovoid or elliptic-ovoid, rounded at 

 the apex, papillate at the base, colorless, 14-18 x 11-13 fx.

Type locality : Formosa. Taihokucho Chonaihosho, Sept. 12,, 

 1908 (Y. Fujikuro), Apr. 5, 1913 (Y. Fujikuro). 



The present variety has noticeably larger-sized conidia than those 

 of the type species described by P. Hennings and later by Sydow
