covery and subsequent confirmatory experiments in Phytopa- 
thology for August, 1915. It is hardly necessary to suggest that 
this has an important bearing on the introduction of the disease 
into far distant localities. 
A large collection of tough and woody fungi was made in the 
hammocks of southern Florida by Dr. J. K. SmaU, Head Cura- 
tor, during February and March, 1915, including two tropical 
species new to the United States and two Gulf Coast species new 
to the subtropical part of Florida. Favoliis variegatus, locally 
known as “ spirit-cups,” was found to occur in great abundance, 
often reaching a foot in diameter. 
Twenty-three new species and several new varieties of fungi 
from North America are described by P. A. Saccardo in a recent 
number of Annales Mycologici. The fungi listed in the article, 
of which there are eighty-eight in all from North America, were 
collected in New York by H. D. House, in Canada by John Dear- 
ness, and in North Dakota by J. F. Brenckle. 
A memoir of the Torrey Botanical Club issued in June, I 9 I 5 > 
consists of a monograph by A. H. Chivers of the genera Chae- 
tomium and Ascotricha. Twenty-eight species of Chaetomium, 
two of which are new, and two species of Ascotricha are de- 
scribed. The memoir contains ninety-five pages of text and is 
illustrated by seventeen heliotype plates. All of the species are 
illustrated and the drawings, made by the author, are excellent. 
The work is a most valuable one for all students of ascomycetes. 
A recent paper by J. R. Weir in the Journal of Agricultural 
Research deals with the possible economic importance of Wall- 
rothiella Arceuthobii, a fungus which is parasitic on false mistle- 
toe. The fungus has not previously been well known, having 
been reported only twice and from widely separated localities. 
The presence of the fungus prevents the maturing of the seeds 
of the host and in this way tends to retard the mistletoe, which 
is very destructive to the conifers in the West.
