lated with spores from a pure culture from the tomato remained 
for ten days in a moist chamber until they ripened without show- 
ing signs of the rot, and cultures made from tomatoes just begin- 
ning to rot would not yield the Al/ternaria. Alternaria Jasciculata 
was found on the dead leaves of beans, cabbage, Lathyrus palustris, 
on hulls of oats and dead stems of buckwheat; also on dead leaves 
of corn where it equals Macrosporium maydis E. & E., on paste- 
board, equalling JZ. chartarum Pk., on ripe pods of radish, equal- 
ling MW. fasciculatum E. & E. 
Doubtless, further investigations will identify many other 
Macrosporium species with this omnipresent saprophyte, and 
doubtless an older name than the one given above will be given 
to it.
