VII, p. 516). The technical diagnosis is given in the Kew 
Bulletin, 1894, p. 84. Prillieux and Delacroix (l.c., p. 80) 
identified it with Coniothyrium melasporum , Sacc., which is 
founded upon a specimen from Porto Rico (not Australia), 
named in manuscript by Berkeley Darluca melaspora and 
described by Cooke. According to Massee (Kew Bulletin, 
1895, p. 86), Berkeley’s type specimen is a Diplodia , and the 
identification of Prillieux and Delacroix therefore falls to the 
ground. 
All analogy would lead to the conclusion that the life- 
history of the Rind Fungus comprises more than one repro¬ 
ductive phase. And this proves to be the case. Massee has 
described the formation of macroconidia ‘ in the interior of a 
cane, when the tissue is disorganized/ and of microconidia on 
a wounded surface exposed to the air. Both these were 
obtained in a flask-culture inoculated with Melanconium - 
stylospores, the microconidia being borne on conidiophores 
growing into the air, the macroconidia being immersed. (Ann. 
Bot., vol. VII, p. 518.) 
Prillieux and Delacroix (l.c., pp. 81, 82) confirm Massee’s 
descriptions of the macro- and microconidia. And generally 
‘ a part quelques points de detail, sans grande importance 
pratique, ils confirment Popinion de M. Massee’ (l.c., p. 75). 
They add still another reproductive stage, that of chlamydo- 
spores ( 1 . c., p. 81). These have also been observed by Howard. 
Went has criticized Massee’s results (Ann. of Bot., vol. X, 
pp. 583-600). His paper was written in Java, where the 
Trichosphaeria , if it exists at all, is ‘ only to be found on dead 
canes’ (l.c., p. 595). But as Professor Harrison points out 
(British Guiana Daily Chronicle, Jan. 15, 1897), the work of 
the Java experts ‘ appeared to be done chiefly with the white 
and purple transparent varieties which were relatively immune 
to some of the diseases affecting the Bourbon/ and Went 
apparently had not seen the research of Prillieux and Dela¬ 
croix. 
Went thinks that Massee’s macro- and microconidia belong 
to Thielaviopsis ethaceticus , which produces the ‘ Pine-apple
