The '‘Bluing" and the “Red Rot" of the Western Yel¬ 
low Pine, with special reference to the Black Hills Forest Re¬ 
serve, Hermann von Schrenk, a paper of 40 pages and 14 plates, 
forms Bulletin No. 36 of the Bureau of Plant Industry, issued 5 
May 1903. Dr. von Schrenk finds the causes of the two phe¬ 
nomena to be fungi respectively as follows: Ceratostomella pil- 
fera (Fr.) Winter, and Polyporus [Fomes] ponderosus von 
Schrenk n. sp. Later publication is promised. 
R. E. B. McKenney reports in Bulletin No. 51, Bureau 
of Plant Industrv, on the Wilt Disease of Tobacco and its Con- 
trol, saying microscopic examination of wilted Tobacco always 
reveals the presence of a fungus belonging to the genus Fusarium 
(Neocosmospora). This is found in the woody parts of the 
roots and stem. The Fusarium is a soil fungus and gains en¬ 
trance to the plants through the Hue roots. 
Observations on Phallus ravenelii, iby Howard J. 
Banker, Torreya, 4:5-8, Jan. 1904, pertains to an abundance 
of “eggs" from the size of a mustard seed to that of a walnut; 
also the mycelium in a pile of sawdust, that protected by a pile 
of lumber being a tangled network and filled with very irregular 
tubercular masses one-half to five centimeters in diameter. These 
tubercles or sclerotia appeared to be enlarged portions of the 
mycelial threads and were twisted, lobed and convoluted in a 
very irregular manner. The white color of mycelium and tu¬ 
bercles quickly turned bluish-purple on exposure to air. 
In Botaniska Notiser foer ar 1903, pp. 249-267, G. Lager- 
heim publishes an interesting article, Zur Kentniss der Bulgaria 
globosa (Schmid.) Fr. (Sarcosoma globosum et S. platydiscus 
Auct.), giving a history of this species, its occurrence and notes 
on its development. It was named Burcardia globosa by 
Schmidel in 1755; this name being preoccupied it was changed 
to Sarcosoma by Caspary. The author points out the insuffi¬ 
cient grounds for maintaining this genus and says: Meines er- 
achtens ist deshalb die Gattung Sarcosoma Casp. einzuziehen 
oder hochstens als ein subgenus der Gattung Bulgaria Fr. zu 
betrachten. A plate accompanies the article. 
The Results of these Experiments prove that pear blight 
may attack apricot twigs and fruit — is the reported result in 
“An Apricot Blight" by Wendell Paddock, Bulletin 84, Colorado 
Agricultural Experiment Station, October 1903. 
R. H. Pettit, Entomologist, Michigan Agricultural 
Experiment Station, reports in Special Bulletin No. 17, a 
fungous disease of the Musquito — Entomophthora sp. nov., 
and a fungous disease of a scale insect (Lecanium longulum), 
namely, Isaria lecanifera Pettit n. sp. “No Isaria sporophores 
were seen but the fungus is placed in the genus Isaria because
