ning from the outside, at least in some cases. Also, mites were 
found in all buds with the characteristic rot. Usually, there were 
but two or three mites in a single bud, sometimes only one, while 
occasionally as many as ten or more were found. 
“ Following an initial determination by Mr. Hodgkiss, Mr. H. E. 
Ewing of the University of Illinois made a careful examination of 
the mites in the diseased buds and found that, except in one bud, 
they were all Pediculopsis graminum Reuter. In the bud excepted, 
the mites were of the species Tyroglyphus lintnert Osborn. This 
bud had been left in a covered lamp chimney used as a breeding 
cage and when examined several days later over 100 mites and 50 
or more eggs of the same were found in the bud, all of which 
proved to be of the last mentioned species. Whether they were the 
original inhabitants that carried the fungus spores to the bud or 
whether they got into the rotting bud accidentally could not be de- 
termined, but in any case they are not the species generally asso- 
ciated with the bud-rot. The fungus which is associated with these 
mites and is the cause of the rot was determined by Mr. J. T. Bar- 
rett of the University of Illinois as a species of Sporotrichum. 
“Flowers attacked by this fungus are not only decayed in the 
center but are also characteristically deformed, sometimes being 
more or less lop-sided and in every case with the inner petals closed 
at the top as if all of the tips of the petals were fastened together 
in the center. 
“So far as I know, all of the carnation growers around Chicago 
use sod soil and renew it every year. At two houses in Centralia 
where examinations were made the bud-rot was not found and 
upon inquiry it was learned that sod soil had not been used.” 
Through the kindness of Mr. Davis we have had an opportun- 
ity to examine two lots of diseased buds from Chicago. The first 
lot consisted of three buds all of which contained the usual mites 
and were abundantly infested with ‘Sporotrichum. The second lot 
contained 13 buds. Three of these proved to be normal. The other 
ten presented the usual symptoms of bud-rot. Nine of the latter 
contained an abundance of Sporotrichum. Some mites, also, were 
present. Both the Sporotrichum and the mites were identically like 
those found in the New York and Nebraska specimens. Eight of 
the nine buds contained no other fungus besides the Sporotrichum, 
but the ninth showed also an undetermined hyphomycetous fungus 
with small, elliptical-oblong, non-septate, hyaline spores. The re- 
maining bud of this lot was peculiar. In a general way it showed
