Lichens—Stereocaulon, Pilophorus and Thamnolia, by 
Carolyn W. Harris, The Bryologist, 7:71-3, Sept. 1904, is a 
popular article with four illustrations in the text. Seven or eight 
species receive notice. 
Bulletin 137, Ontario Agricultural College, is devoted 
to a Bacterial Disease of Cauliflower and Allied Plants, author 
F. C. Harrison. A brief introduction is followed by a consid¬ 
eration of the subject under the heads of Pathenogenesis, Patho¬ 
logical History, and Inoculation experiments. 
A short article, with ten beautiful half-tone plates, on 
Abberant veil Remnants in some edible Agarics, by William Tre- 
lease, was published in the 15th Annual Report of the Missouri 
Botanical Garden. The species represented are Lepiota nauci- 
nus, Agaricus amygdalinus and Hypholoma appendiculatum. 
Under the head of Tobacco Diseases and Tobacco 
Breeding, the Ohio Agricultural Experiment Station issued Bul¬ 
letin 156, November 1904, by A. D. Selby. In the section giving 
account of diseases due to parasitic fungi and Bacteria we find 
the following listed: Root rot (Black Rot) [Thielavia basicola 
Zopf]; Bed Rot [Rhizoctonia] ; Decay of Tobacco Seedlings [Al- 
ternaria-A. tenuis?]; the Granville Tobacco Wilt; Leaf Blight 
(Frog-eye) [Cercospora nicotiana E. & E.]; White speck and 
Brown spot [Macrosporium tabacinum E. & E., and M. longipes 
E. & E.] ; Downy and Powdery Mildew. 
An interesting lecture, largely historical, on the Study of 
Parasitic fungi in the United States, by G. P. Clinton, before 
the Massachusetts Horticultural Society, is printed in the Tran¬ 
sactions, 1904, Part I, pp. 91-106. 
O. Appel und R. Laubert: Die Konidienform des Kar- 
tofflepilzes Phellomyces sclerotiophorus Frank. Berichte der 
Deutschen Botanischen Gesellschaft, 1905 [23:218-220]. The 
authors succeeded in inducing the stromata of this fungus of 
which hitherto “neither in nature nor by culture, has any typical 
fungal fructification been observed,” to develop and they ob¬ 
tained a form identical with Spondycladium atrovirens Harz. 
“Aus den in gekiirzter Form hier vorlaufig mitgeteilten Unter- 
suchungen geht hervor, dass der Pilz, der von Frank als Phello¬ 
myces sclerotiophorus beschrieben und als Krankheitserreger in 
die phytopathologische Literatur eingefuhrt worden ist, nur ein 
noch steriler Entwicklungszustand des Sponlycladium atrovirens 
Harz ist und dass infolgedessen der “interimistische Name 
Phellomyces sclerotiophorus Frank” zu streichen und durch 
“Spondycladium atrovirens Harz” zu ersetzen ist.” 
The Agricultural Experiment Station issued a Bulletin, 
No. 64, (1904) on the Apple Scab in Western Washington by W.
