Another fungus was found which 
produced a roughness on the sur- 
face of the tomato, and usually 
made a rather dry mass beneath 
as far as its abundant white myce- 
lium extended. It corresponds very 
well with the figure and description, 
by Saccardo,* of Gloeosporium pho- 
moides, which was found upon  to- 
matoes in Italy in November, 1878, 
and may be identical with it. The 
fungus develops just beneath and 
within the epidermis or skin of the Bigg, S-Oidiumlacites Rew trom
