The four species of Cordyceps known from Japan are as follows: 

 CORDYCEPS GUNNII (see Synopsis of the Cordyceps of Aus- 

 tralasia, page 6, fig. 618). This is known from a single collection at 

 Museum of Paris. It is a large Australian species, and has never 

 been collected outside of Australia, excepting this one Japanese col- 

 lection. 



CORDYCEPS SOBOLIFERA (see Myc. Notes, page 529, fig. 

 721). This is a species of the West Indies, said to be common there, 

 but not known from any collection in the museums now r . It grows 

 on the Cicada. A specimen was sent me from Japan by Dr. Kawa- 

 mura, the only specimen I have seen. Dr. Kawamura reports it as 

 common in Japan, but none of my other correspondents have met 

 with it. 



CORDYCEPS NUTANS (see Myc. Notes, page 529, fig. 720). 

 This is apparently the most frequent Cordyceps in Japan. It grows 

 on a Hemiptera, and (excepting the next) is the only species recorded 

 on this bug. I have specimens from J. Umemura and also A. Yasuda, 

 from Japan. 



CORDYCEPS TRICENTRUS (Fig. 775), FROM PROFESSOR 

 A. YASUDA, JAPAN. Stipe slender, 1 mm. by 6 cm. Head nod- 

 ding, smooth, \y 2 mm. by 7 mm. Entire plant yellow. Perithecia 

 not prominent. This species grows on Tricentrus, and is 

 very similar to Cordyceps nutans. It differs in its host, 

 Tricentrus a name we have not located in any entomological 

 work in our library and in its color, pale yellow in all its 

 parts. Cordyceps nutans has a black stem below and deep 

 orange above, as in the club. We present a figure (Fig. 775) 

 made from a drawing sent us by Professor Yasuda. Also a 

 photograph (Fig. 776), enlarged six diameters, of the Cordy- 

 ceps club. From the figures, the species cannot be told from 

 Cordyceps nutans, and it grows on a 

 similar host. The only difference is 

 the color, as noted above, and which 

 is quite marked, according to Profes- 

 sor Yasuda, and he is familiar with 

 both species. It is probably better, 

 however, to consider it as a form of 

 Cordyceps nutans. 



ISARIA ATYPICOLA (see Letter 

 Fig. 775. 56, Note 257). This occurs on a 

 large, burrowing spider, and much re- 

 sembles to the eye a Cordyceps. Its fruit, however, is only conidial, 

 hence it is an Isaria. Most Isarias are supposed to be preliminary 

 stages of Cordyceps, and this probably is; but the Cordyceps form 

 has never been found. We trust those living in Japan will watch 

 closely for a Cordyceps, on their burrowing spider.
