Phoma lanceolata. But the specimens on Gladiolus, Dahlia, and 
Asparagus, are all very much alike and belong to the same group 
as the Phoma fusigera already mentioned (see under no. 910). 
They probably belong to Diplodiae such as D. Georginae, Lév., 
but what they really mean cannot be decided now. Cooke gives 
the spores on Asparagus as 30 X 7, but none so large were 
seen; they were mostly even shorter pi ee on Gladiolus.

The following specimens were examined :— 
“ Sphaeropsis Musarum,” Cooke, Herb. no. 230!, wateiiem, 
India, coll. Hobson. (Fig. 4a.) 
“M acrophoma Musae,”’ see Fung. Exot. Exs. no..189!, 
Manilla, coll. Graff. (Fig. 40.) 
(Both of these are on dead leaves of Musa paradisiaca, but it 
is also pat i by Petch on fruits of Plantain, Peradeniya). 
IPLODIA Rapvuta,” Herb. Berk.n o. 305!, on leaves of 
Musaceae, Ceylon. (Fig. 4c. 
Cooke’s specimens (no. 230) have the pycnidia in dense round 
clusters: they suggest at the first glance a Botryodiplodia, for 
under the microscope all the characters of a young Diplodia are 
present, except that there were no sporophores visible. Now 
Berkeley described his Diplodia Radula on leaves of Musaceae, 
but his specimens (no. 305) show no signs of having the pycnidia 
conglomerated ; nevertheless the gap is bridged over by Sydow’s 
specimens (no. 189), for in them there are numerous single 
pycnidia, and also they show many clusters exactly like those of 
Cooke’s no. 230. 
It is Higgs suggested that Macrophoma Musae = Diplodia 
Radula, B. & Br., although with reservation. The spores of 
both are all but the same, for most of the spores of Berkeley’s 
specimens of his Diplodia are colourless, though granular, and 
are nearly of the same size and appearance: only a few of the 
older pycnidia were exuding long strings of brown 1-septate 
spores. Sydow’s spores are smaller than those of Cooke. In all 
these specimens, including D. Radula, no sporophores are now 
discernible; this is known also to be the case in D. atrata.— 
In Berkeley’ S$ specimens (no. 305) long slender gelatinous para- 
physes occur similar to those which are found in some pycnidia 
of Botryodiplodia Theobromae, Pat., and the pycnidial walls 
show traces of the same violet- or purple-brown tinge as it 
possesses. Is it possible that the Diplodia on Musa is only 
a biologic form of B. Theobromae? Musa is not mentioned 
among the hosts of that species by Petch (see the next no.
