production of conidia seems to have ceased, and the ends of the 
hyphe terminate in the enlarged bodies. 
The Gloeosporium found on the quince produces also a dark 
brown depressed spot which increases by well-marked concen- 
tric rings. The tissue remains quite firm, becoming more oF 
less hardened, and frequently cracks. In the growth characters 
of the colonies, and in the habit on bean stems, the resemblance 
to the species found on the apple is so close as to leave no 
doubt that the two fruits are infested by the same species ; the 
slightly different effect produced on the host being doubtless 
accounted for by the firmer tissue of the quince. Professor 
Halsteds further confirmed the identity by inoculating the 
quince with “virus” obtained from the apple. The writer has 
also successfully transferred the Glceosporium from the quince to 
the apple. However, since these forms easily adapt themselves 
to artificial cultures and are in a measure saprophytic, too much 
importance should not be attached to the results of laboratory 
inoculations, where the conditions are more or less artificial. 
No indication of a yeast form has been found in connection 
with the development of the species, 
GLa:OsPORIUM PHOMOIDES Sacc. ( figs. 5-7, 39-41); on tomato 
(Lycopersicum esculentum). 
An anthracnose causing a ripe rot of the tomato is mani- 
fested at first by a small circular depressed area. Older spots 
show a lighter central portion surrounded by a dark marginal 
band 2-3™ in diameter. Upon the central portion, the dark- — 
colored fruiting pustules first appear, producing irregular fissures 
in the epidermis, which often turns a bright yellow on the ma 
gins. From the pustules the conidia ooze out in light pink : 
masses. With age the diseased portions become quite black. : 
The spore measurements vary considerably from those giver 
in Saccardo (3:618), some of them measuring 18.5 X 5-O#- fe 
shape they may be oblong, elliptical, fusoid or reniform, and 
sometimes curved. —
