I have not been able to examine the large number of forms 
included by Saccardo under Monilia. Of these it is probable 
that many have no real affinity with that above discussed; 
while others may be closely related. ‘Such appears to be the 
case with a rather common form which attacks the immature 
fruits of Prunus serotina and related species, forming delicate 
white tufts, with spores very like, but somewhat smaller than 
those of M. fructigena. This is probably the plant called by 
Saccardo?® Monilia Peckiana, var. angustior. The few cult- 
ures I have been able to make have yielded only the common 
spore-chains, but the form will probably repay further investi- 
gation as to its pleomorphism and its affinities. -
