Tanaka : New Japanese Fungi 



327 



globose or depressed-globose, 260-350 /x broad, 130-170 li high, 

 wall fungoid-parenchymatous, black, 12-15 ^ in thickness; ostiola 

 separate but grouped, elongate, 30-300 /x long; asci clavate' or 

 cylindrical, rounded at the apex, narrowed into pedicel at the base, 

 25-30 x 4-5 fx, aparaphysate, octosporous ; ascospores distichous or 

 irregularly distichous, cylindrical, rounded or truncate at both 

 ends, usually curved in one direction, rarely straight, hyaline or 

 flavescent, 5-10 x 1.5-2 li. 



Parasitic on weakened trunk of The a sinensis. 



Type locality: Shidzuoka-ken Hamana-gun Hikuma-mura, De- 

 cember 12, 1918. (K. Hara.) 



Illustration : One half-tone text figure showing cross-section of 

 a stroma with perithecia, asci and ascospores. (Fig. 9.) 



Notes: There are two species of Valsa found on the tea-plant, 

 but it is still undetermined which causes the die-back of the trunk. 

 The other species not described here has no stroma, though it re- 

 sembles this species in other respects. The latter is left unnamed 

 until its characters are more fully studied. 



Diatrype Theae K. Hara sp. nov. in Chagyokai (Tea Journal) 



14 11 : 19. T. 8, xi, November, 1919. (Japanese.) 



Stromata subepidermal, later erumpent, oblong or linear, 1-2 

 mm. long, 0.5-1 mm. wide, cross-section oblate-urceolate, slightly 

 rounded at the upper part, flat or somewhat concave at the base, 

 with a broad neck at the top, cinereous, more or less parenchyma- 

 tous ; perithecia deeply immersed in the stroma, globose or ovoid, 

 300-330 fx high, 100-170 jx in diam., wall parenchymatous, dark 

 colored, 15-30 /x thick, long ostiolate; ostiola penetrating the stro- 

 matic neck, opening round, 20-25 /x across ; asci clavate or obovoid, 

 apex usually narrowed, rarely swollen and rounded, base tapering 

 very much into a filiform pedicel, 20-40 x 6-8 li, aparaphysate, 

 octosporous ; ascospores cylindrical or f usoid, rounded at both 

 ends, straight or curved, plane or nucleate at both ends, hyaline or 

 flavescent, 7-1 1 x 2-2.5 



Saprophytic on the trunks of Thea sinensis. 



Type locality : Shidzuoka-ken Abe-gun Okawa-mura, October 

 24, 1918. (K. Hara.) 



Differs from Diatrype stigma (Hoffm.) Fr. in the shape of the 

 stromata^ also from D. Hochelagae E. & E. in the aparaphysate 

 asci. The former is found in the same village where the present 

 species was discovered.
