Notes: The finding of aecia on Pyrus spcciabilis by Shirai in 

 Tokyo was reported by Dietel as ? Gymnosporangium claviaeforme 

 Jacq. {in Hedwigia 37: 216. July, 1898) and by P. Sydow as 

 Gymnosporang'mm ? clavariifonnc (Jacq.) Rees (do. Beibl. 37^: 

 (207) Nov.-Dcc, 1898). ]\ Hcnnings listed an accAuii on Pyrtis 

 Toringo collected by Shirai at Nikko as ? (7. clavariifonne (Jacq.) 

 Rees (in Engler's Bot. Jahrb. 28: 262. Mar., 1900), and he later 

 reported G. clavariifortnc from Tokyo, found by Hori on P. spec- 

 tahilis (do. 31'"': 72,2. Aug. 1902). The^e are all iikely to 

 represent G. Yamadac. Under G. Yamadae Miyabe sp. nov., 

 Kern presented a description of the aecial stage found on Pyrus 

 spcctabilis by Nambu at Tokyo (in Bull. N. Y. Bot. Gard. 7-": 

 466. Oct., 191 1 ), and Sydow later described the telial stage under 

 the same name from material presented by M. Miura (in Ann. 

 Mycol. 12: 159-160. Apr., 1914). Ito (in Byodiu-gai Zasshi, 

 Journ. PI. Prot. 4*: 244-245. Apr., 1917) ventured, however, to 

 bring this name into the synonymy with G. chinensis Long (in 

 Journ. Agr. Res. i : 345. Jan., 1914) but all later investigators 

 have considered the latter to be identical to G. asiaticiim (= G. 

 haracanum = G . korcacnsis). Sec Clinton, in Ann. Rept. Conn.
