H. Lawrence, of which this is his summary: Apple scab is 
abundant and destructive in Western Washington. The apple 
scab fungus has two stages — a summer, or parasitic stage [Fu- 
sicladium dendriticum], and a winter, or saprophytic stage \Fen- 
turia acqualis). The summer stage infests the leaves, flowers and 
fruit; the winter stag'e lives in the dead leaves of the apple which 
fall off in autumn. The winter stage produces the spores that 
cause the infection of the flowers, leaves and fruit in spring. 
To destroy the fungus, destroy the fallen leaves in the fall or 
winter. To prevent the fungus attacking the apple in spring, 
spray with a properly prepared Bordeaux mixture. 
On a Fungus Disease o-f Euonymus japonicus Linn. f. 
by Ernest S. Salmon is reprinted from the Journal of the Royal 
Horticultural Society, Vol. XXIX, Part 4. The parasite in 
question is Oidium euonymi-japonicae (Arc.) Sacc. A half-tone 
illustration of affected leaves is given, also outline figures of 
conidia, appressoria and haustoria. It is stated that a pecu¬ 
liarity of this Mildew is the capacity it possesses of persisting 
by means of hibernation of its mycelium. As to its introduction 
the author says: It seems, then, more probable that the fungus 
may have been lately brought to Europe on diseased plants im¬ 
ported from Japan than that a European species of Oidium has 
of late years spread from its original host and attacked E. japo¬ 
nicus as a new host-plant. On the former theory we find an ex¬ 
planation of the fact mentioned above, viz. the epidemic charac¬ 
ter of the disease now beginning to be shown by the Oidium in 
Europe, since it is an established fact that a parasitic fungus 
on reaching a new country attacks its host-plant with exceptional 
virulence for several years after its arrival. 
New or rare Pyrenomyceteae from Western New York, 
by Charles E. Fairman, Proc. Rochester Acad. Sci. 4:215-224, 
March 1906, containing Nos. 355-380, is supplementary to his 
list of Pyrenomyceteae of Orleans County, N. Y., printed in the 
same volume. Nos. 355-364 are new species by Fairman; Nos. 
365-6 are new species by Rehm; notes and supplementary de¬ 
scriptions are given for Nos. 367-380. One full page illustra¬ 
tion is devoted to Sporormia leguminosa Fairman n. sp. and one 
to Amphisphaeria aeruginosa Fairman n. sp., Sporidia and other 
parts of several of the new species occupy another plate. 
Charles Horton Peck, New species of Fungi, Bull. Torr. 
Bot. Club, 33:213-221, Apr. 1906, describes 22 species of the 
higher Fungi, mostly belonging to the following genera; Lepiota, 
Hygrophorus, Collybia, Russula, Lentinus, Annularia, Inocybe, 
Flammula, Psathyrella, Hydnum, Craterellus, Monilia, Marsoma, 
Haplosporefla, Sarcoscypha, Poronia, Leptosphaeria, and Pleo- 
spora.
