half, pierced by a pore, surrounded by dark-brown creeping 
hyphae, at length collapsed; texture thick, opaque, dark-brown. 
Spores elongate-fusoid, rounded at both ends, granular, colourless, 
20-25 x 4-5-5-5; sporophores oblong, thick, more or less 
curved, blunt at apex, colourless, 15-16 x 3-4. (Fig. 3a.)

In some of the larger pycnidia actual Diplodia-spores were to 
be seen, translucent, pale-brown, somewhat fusoid, 18—20 x 5-6 p, 
but no intermediate stages could be detected. Nevertheless, it 
is impossible to come to any other conclusion than that the 
two kinds of spore belong to the same fungus: the cases now 
established of such a connection are too numerous to permit of 
any doubt. So far, however, no Diplodia on Gladiolus seems to 
have been described. The appropriate name for this would be 
Diplodia elongata ; the species of the genus, which have spores 
that are fusoid when young, should form a distinct section, the 
Fusisporae. See nos. 910 and 994.
