little shorter, not over S /x in length. Dr. Stoker writes that some 
Poles who collected mushrooms for food knew the plants and 
called them “pig’s ears,” which is the popular name for Caiv- 
tharellus clavatus in parts of Europe. The species appears to be 
more frequent in the Lake Superior district than in the East, 
where the closely related Cantharellus floccosus is more fre- 
quently met with. I have never collected Cantharellus floccosus 
farther west than the Muskoka Lake region in Ontario. Speci- 
mens of that species have been sent to me recently, collected b\ 
S. E. Hutton in New Hampshire. The species has been described 
by Peck and Murrill and illustrated by Peck, Hard, and Nina 
Marshall. As noted by Peck, the two species, Cantharellus 
floccosus and Cantharellus clavatus, form a distinct group agree- 
ing with each other in general characters, nature of the lamellae, 
and color of the spores. The two species differ in color and size 
of spores, and in the fact that Cantharellus clavatus is solid with 
the pileus truncate or but little depressed and nearly smooth, 
while Cantharellus floccosus has the pileus floccose-scaly and 
trumpet-shaped or infundibuliform and hollow to the base, with 
thin flesh. The stem in both species is normally short, but in 
Cantharellus floccosus it is sometimes lengthened and curved, ex- 
tending deep into the mould. In all the collections I have seen, 
these distinctions have been marked. So far as I am aware, 
Cantharellus floccosus has not been identified with any European 
form

A Book on Tropical Plant Diseases 1 
While works on plant pathology are becoming quite numerous, 
the present book is a pioneer in a new field, as no other work in 
English attempts to cover in adequate fashion the diseases of 
tropical plants for the entire world. Indeed, the literature of the 
subject is so scattered that few libraries can offer adequate facili- 
ties for the study of tropical plant diseases without such a guide
