Vol. XIX, p. 45. He described this fungus from a specimen of 

 sugar cane labeled Bailey 871 from Queensland, as follows: 



"Pustules gregarious, erumpent, black, patelloid or subclavate, with a short 

 stemlike base, or cylindrical multiform (Yj mm. diam.), hyphae short, hyaline, 

 simple; conidia cycindrically elliptical, continuous, pale fuscous, 10-12x3 mi- 

 crons." This description is purely one of the fungus and does not indicate 

 the symptoms of the disease other than to say that the pustules are erumi^ent. 



In 1878 Cooke published a description (8)^ of one of Berkeley's 

 species as follows: 



Darluca Melaspora Berk, in litt. Pustulis prominulis, nigris, sporis oblongis 

 binucleatis, cirrhis nigris. . 015 x. 115 mm. From sugar cane in Australia. 



In 1892 was published a new species by Ellis and Everhart in a 

 paper by Cockerell (7). The name of the new fungus was TruUula 

 sacchari and its description as follows: 



Aeervuli innate-erumpent or entirely black, conicglobose, % to Vz mm. diam., 

 resembling perethecia. Conidia catenulate, forming at first a continuous, hyaline 

 filament, 70-75 microns long, soon separating into oblong 2-.3 nucleate, olivaceous 

 conidia, 8-11x21^-3' microns, rounded at the ends, and closely resembling the 

 sporidia of some Hypoxylon. The chains of conidia are densely crowded and 

 simple. The erumpent aeervuli blacken the surface of the culm with the dis- 

 charged conidia, but some of the aeervuli are entirely buried in the inner sub- 

 stance of the culm and are apparently never erumpent. Found in Jamaica, 

 Barbados and Trinidad on sugar cane. 



In 1893 Massee (26) described the black erumpent fungus on 

 sugar cane as a Melanconium stage of Trichosphaeria sacchari. In 

 a later paper (27) he gave the succession of these various stages 

 as follows: from Melanconium stage to macro- and micro-conidial 

 stages and thence to the ascigerous stage which he called Triclio- 

 sphaeria sacchari. His work was based on material received from 

 Trinidad and other English colonies. 



Fawcett (14) in 1894 wrote that he found Trichosphaeria sac- 

 chari (the Melanconium stage) present in Jamaica, but he found 

 other diseased material, which he" sent to Kew and which was exam- 

 ined by Massee and pronounced Collet otrichum falcatiim. Later he 

 Avrote (15) that he found Trichosphaeria (Melanconium stage) and 

 that Massee considered it only a form of Colletotrichum falcatnm. 



In 1895 Saccardo (32) changed the name of Cooke's Darluca 

 melaspora to Coniothyrium melasporum. In the same year Prillieux 

 and Delacroix (31) studied material from Mauritius which showed 

 the same black erumpent fungus on the cane as did Darluca and
