the confusion by changing the name to Coniothyrium mela- 
sporum , and by quoting Cooke’s diagnosis incorrectly in Syll. 
Fung., vol. iii, No. 1799. 
‘ Finally, Prillieux and Delacroix, in their paper on Sugar- 
cane Diseases (Bull. Soc. Mycol. de France, tom. xi, p. 75, 1 895), 
have fallen into the error of considering the Melanconium- 
stage of Trichosphaeria Sacchari (Massee) to be synonymous 
with Coniothyrium Melasporum , (Berk.) Sacc. Examination 
of Berkeley’s type specimen shows that the Fungus is a 
Diplodia * 
There can hardly be any doubt that this Diplodia is iden- 
tical with the species discussed in this paper.

EXPLANATION OF FIGURES IN PLATE XXXVII. 
Illustrating Mr. Howard’s paper on Diplodia cacaoicola. 
Fig. 1. Portion of the stem of a sugar-cane, showing the pycnidial colonies 
of the Fungus breaking through the rind. Nat. size. 
Fig. 2. Transverse section of the sugar-cane stem, showing pycnidia. Zeiss, a a. 
Fig. 3. Transverse section of a pycnidium breaking through the rind of the 
sugar-cane. Zeiss. D D. Drawn with the help of a camera lucida. 
Fig. 4. Stages in the germination of a spore obtained from a pycnidium on 
a diseased sugar-cane. The sowing was made at 9.30 a.m. Dec. 22, a , at 
3 p.m. ; b, at 3.55 p.m. ; and c, at 5 p.m. the same day. Temp. 27-29° C. At 
8 a.m., Dec. 23, a hypha had developed from the other half of the spore, but the 
single-spore colony was too complex to draw, x 375. 
Fig. 5. Stages in the germination of a young spore in which the transverse 
septum has not yet appeared. The spore was obtained from a pycnidium from 
a diseased sugar-cane, and the sowing was made at 9.30 a.m., Dec. 22 ; a, at 
1 1.30 a.m. ; b, at’12 noon ; c, at 1.30 p.m. ; and d , at 4 p.m. the same day. Temp. 
27-29° C. a, b, c x 375. dx 6 o. 
Fig. 6. Stages in the fusion of hyphae in a hanging-drop, two days after sowing : 
a, at 2.5 p.m. ; b, at 4.45 p.m. ; and c , at 5.0 p.m., Dec. 24, Fusion was complete 
at 5.30 p.m. the same day. x 375.
