A fungus exactly like it in appearance has been found on Sida spinosa 
by Mr. W. T. Swingle at Manhattan, Kans. Some attempts at produc¬ 
ing tiie disease on hollyhock by the spores from Sida have been made, 
but as far as known they have not been successful. This might easily 
be accounted for by the lateness of the season and consequent low 
temperature, and it seems almost certain from a comparison of the 
fungi that they belong to the same species. 
Dr. P. A. Saccardo writes that the fungus is probably not a new 
species at all, but was described in 1854 by Braun and Caspary as 
Steirochcete malvarum on Malva in Europe (Sacc. Syll., IV, 316). The 
descriptions certainly agree in many respects, but the description in 
the Sylloge reads, “Conidiis ex pseudostromate immediate (ut videtur) 
orientibus,” and the spore measurements are given as 8-9 x 3-4 //. In 
the fungus on hol^-hock there was no question as to the spores being 
borne on basidia and they measured 11-28x 5 p. The fact of the spores 
being borne an basidia may, however, have been overlooked, and as the 
spores vary greatly anyway, the difference in size is not sufficient 
reason for making a new species. 
After comparing the two descriptions it seems very probable that 
the fungus must stand as Colletotrichium malvarum , (Br. & Casp.). 
There also seems to be a possibility that Steirochwte graminicola , 
(Ces ) Sacc. may be identical with Colletotrichium bromi , Jennings, an 
nndescribed species on Bromus secalinus , noted in Bull. 9 of the Texas 
Experiment Station.— E. A. Southworth. 
LEPTOTHYRIUM PERICMYMENI, DESM.* 
x Specimens of what seemed to be this species on Lonicera , sent this sea¬ 
son from Perry Sound, Ontario, Canada, by Mr. Dearness, have the 
sporules (pseudo) septate near the lower end and agree accurately with 
the description and specimens of Marsonia lonicerce , Hark., except in be¬ 
ing mostly shorter (22—30x7 — 9yu). European specimens in Thiim. M. 
U. 1893, Kunze, F. Sel. 591, Linliart 474 and F. G. 4674 do not show 
any septum, though the F. G. specimens show some indications of one. 
The European specimens also have the sporules less attenuated below. 
In the specimen from Dearness and Harkness the lower part of the 
sporule is so much narrowed as to appear like a stipe or pedicel. The 
Canadian and Californian specimens are certainly the same and can not 
be referred to Marsonia , as they have a very distinct scutellate perithe- 
cium of radiate fijbrous texture. We propose to designate the American 
form as Leptothyrium perichymeni , Desm. var. Americanum , E. & E.—J.
