Tanaka: New J.\1'ani:sk Fungi 152 



Locality: Northern Japan (very common). 



Illustration: Two collotype plates showing infections of twigs 

 and fruits of apple, one lithograi)hic plate giving detailed struc- 

 ture of the fungus in various stages. 



Note: The fruit spot of apple (Hcikwa uo Hantenbyo in Jajja- 

 nese) here described is very widely distributed throughout the 

 territory, most frequently occurring on Jonathan apple, the 

 spotted fruit of whicli i5 almost considered as characteristic of 

 the variety. Though closely resembling Phoma Pomi Pass, in 

 the cylindrospore formation, the Phomopsis stage is entirely 

 dil'fercnt from that, indicating a common identity with Plioinopsis 

 Mali Rob. which is reported as occurring only on twigs and not 

 on fruits. The discovery of the ascogenous form in culture 

 enabled the investigator to prove these observed forms stages 

 of Diaporthe. " Diaporteose " is proposed as the new English 

 name for this disease.

III. Telia hy{)ophyIlous, elongated, orange yellow, {|uite con- 

 spicuous macroscopically as silky protrusions of veins through 

 laciniately ruptured epidermis, discoloration of the upper surface 

 being brownish, the margin of which is rather indefinite ; hyphae 

 bundles projecting from cortical as well as bast portion of sub- 

 strata attain to 2.200 /u, in whole length when measured with tclio- 

 spore bundles ; teliospores elongate-lanceolate with conspicuously 

 long pedicels, mostly 5-celled, gradually narrowed and sharply 

 l)ointed at the apex, 136-221 X I5-6)U,, the terminal cell occupying 

 nearly one half of total length, slightly constricted at the septum, 

 membrane smooth, equally thick, hyaline, 2 /a across, contents 

 granular, mixed with oil globules, orange yellow ; pedicels very 

 long, average 2.000 /* in length, membrane thicker than that of 

 spore, measuring 3 /x across, smooth and hyaline, contents also 

 hyaline.
