upon the tomato. This one of the pear and the pod-spot 
Colletotrichum of the bean were at the same time introduced upon 
different areas of a citron, and the two in growing produced a 
blending anthracnose blotch made up of a single species of 
Colletotrichum. It is therefore shown that the chain of evidence is 
strong that all three of the Solanaceous plants are preyed upon by 
the same Colletotrichum, and that it is the one so familiar to truck 
growers as the pod-spot fungus, namely, Colletotrichum Lindemutht 
anum,S.& M. Whatever differences in appearance upon the various 
hosts there may be they seem entirely due to the varying condi- 
tions which attend the growth of the anthracnose. The microscope 
is not sufficent to distinguish from which host the fungus has 
been taken for inspection. 
If these cultures give the true relation of the anthracnoses it is 
evident that the view now held by mycologists may need some 
modifications to fit the facts. In an economic aspect the informa- 
tion has its value as it shows a close connection between the . 
anthracnoses of the several garden crops. ‘That is, one fruit does 
not blight to its own kind alone. A decaying tomato or apple is 
neither its brother’s nor its cousin’s keeper.

Two New Species of Mosses from Idaho. 
By J. B. LEIBERG. 
(PLares CXLIIL—CXLIV.) 
DiITRICHUM MONTANUM n. sp.—Plants czspitulose, I-2 cm. in 
“length, fastigiately branching from the base, above more or 
less dichotomous. Monoicus, seldom synoicus; antheridia 
terminal on the apex of the basilar branches and of short 
axillary branchlets, few, without paraphyses; perigonial leaves 
3-5, of two sorts, short, serrulate, concave, apiculate, costate, 
loosely areolate bracts, and longer, broadly costate, canaliculate 
ones, more compactly areolate, resembling the stem leaves 
but shorter, the two sorts occurring together, and now the one 
and now the other enclosing the antheridia. 
Stem leaves erect or slightly curved, lanceolate below, chan- 
neled and subulate above with a narrow lamina of two to three 
rows of cells, subserrulate and inflexed margin of two rows of 
cells, apex coarsely toothed; costa broad, strong, ceasing below
