the writer Peziza-bearing sclerotia from such a disease of this 
plant. Pammel (Trans. St. Louis Acad. 6: 1091. 1893) has 
described a similar disease. W. G. Smith (Gard. Chron. III. 
8: 324. 1890 and III. 9: 791 1891) describes a stem rot of 
hollyhocks caused by Sc/. Libertiana. The disease was entirely 
similar in all these cases and needs no extended description. 
The stem of affected plants rotted just above the ground, being 
filled with a vigorous mycelium as in the diseases already 
described. Sclerotia were produced both upon the surface and 
in the interior cavity of the stem, from which the Peziza form 
readily developed. 
A disease of clover has been described by several writers 
which is very similar to those under consideration but ascribed 
to Sclerotinia Trifoliorum Erik. which is regarded as distinct from 
Libertiana though apparently very similar. The writer received 
alfalfa plants from Mr. F. C. Stewart of the New. York Exp. 
Station which were supposed to be affected with this species. 
The sclerotia, however (text jig. 1 e), both from diseased stems 
-and cultures, were entirely similar to those of Liberfiana, and 
produced a Peziza form which left no doubt that it was that 
species, 
V. General conclusions on Sclerotinia Libertiana and Botrytis 
cinerea. 
During the four years in which this work has been carried on 
a great deal has been done which has no special connection with 
that part of the subject with which the present article deals. A 
large amount of material has been obtained and the fungi grown 
and studied under all sorts of conditions. Most of the results which 
it is intended to emphasize here have already been brought out in 
various places in this description. It is maintained above all that 
Sclerotinia Libertiana and Botrytis cinerea have no connection whatso- 
ever with each other, and that the Jormer species has no conidial stage 
of this type. Growing either as a saprophyte or parasite, it shows 
at all times a mycelium composed of large, branching, septate 
filaments, averaging about 10-15 in diameter, which produce
