67. T. 2, i, Jan., 191 3. Japanese). This identification was made 

 by Sydow according to Hara's second report (1. c. 27 319 : 348. 

 T. 2, vii, July, 191 3. Japanese), but as he had formerly succeeded 

 in inoculating Amelanchier he considered this to be identical, at 

 least partly, to G. juniperinum mentioned by Shirai in his " List " 

 p. 39. Hara later obtained materials from Yamada who proposed 

 the present scientific name according to the results of his inocu- 

 lation. See Engei no Tomo (Friend of Hort.) 13 9 : 812. T. 6, 

 ix, Sept., 1917 (Japanese). 



The present species was later acknowledged by Ito as a distinct 

 species, differing from G. clavariiforme by having much flatter 

 telia; from G. amelanchieris in the elongated shape of the telio- 

 spores; and from G. clavipes in the different shape of the pedicel 

 of the teliospores. See Byochu-gai Zasshi (Journ. PI. Prot.) 4 5 : 

 325-326. T. 6, v, May, 191 7 (Japanese). 



Hara's descriptions are based upon the specimens collected at 

 Kawauye-mura, Mino province (Gifu-ken) (O. I. III.) ; various 

 localities in Totomi province (Shidzuoka-ken) as Sakabe, Makino- 

 hara, Kasuisai, and Mikatagahara (III.).
