plants were found to be readily susceptible to inoculation. Mr. 
Sheldon also demonstrated that the Carnation Rust is local in¬ 
stead of being distributed throughout the plant, and that cer¬ 
tain varieties are practically immune. It is interesting also to- 
note that observations have led to the opinion that Darluca filum 
Cast, is not parasitic on the Rust, its saprophytic tendencies hav¬ 
ing been demonstrated by growing it on various culture media.. 
“There are strong indications that it may be parasitic on As¬ 
paragus.” 
European Fungus Flora, Agaricaceae, George Massee,. 
F. F. S., is the title of a recent important book of 274 pp., pub¬ 
lished by Duckworth & Co., London. For each of the five pri¬ 
mary divisions of the group (based on the color of the spores as 
seen in mass), a concise synoptical key to the genera is given, 
followed by descriptions of 2750 European species (of which 
1 553 are British). “The idea of this work is to give the essential 
characters of each species as presented by pileus, gills, stem and 
spores respectively.” No figures are given. The author thinks 
that “a lengthy and laboured description suggests lack of power 
to grip essentials on the part of the compiler, and does not as 
a rule facilitate the recognition of the species intended.” An il¬ 
lustration or two will show the character of this treatise. For 
exajmple, p. 7, under the genus Lepiota is given this description :— 
“Procera, Scop. P. soon expanded, umbonate, with brownish 
scales, 10-25 cm.; g. free, crowded; s. 12-20 cm., base thickened, brown¬ 
ish, transversely cracked, ring free; sp. 12-15x8-9. Edible.” 
On p. 205, under the genus Agaricus occurs the following 
paragraph:— 
Campestris, L. 6-12 cm. convex then plane, floccosely silky or 
fibrillose, whitish, flesh reddish-brown when cut; g. close to stem, subli- 
quescent, fleshy then umber; s. stuffed, even, white, ring median, torn; 
sp. 7-8x5-6. Edible. 
Var. alba, Berk. P. rather silky white; s. short. 
Var. hortensis, Cke. P. fibrillose or squamulose, brownish. The 
variety commonly cultivated in England. [Eleven other vars. given under 
this speces.] 
A New Mushroom for the Market is reported by H. 
Webster in Rhodora, 4:199, October, 1902. The plant referred 
to is Lepiota naucina — and this with several species as Agaricus 
campestris, Coprinus atramentarius, Coprinus comatus, Tricho- 
loma personatum, have found a ready sale in the Boston market. 
Prof. Dr. P. Magnus gives in the Berichte der Deutschen 
Botanischen Gesellschaft (20:291-296, 1 pi. 1902) an account of 
a species of a root-inhabiting, gall-producing Urophlyctis which 
is the cause of a destructive disease of Medicago sativa, or Lu¬ 
cerne. F[e refers to his previous assertion, dass die Gattung Uro¬ 
phlyctis Schroet. eine gute Gattung ist and scharf von den Gat- 
tungen Physoderma und Cladochytrium zu trennen ist. He also
