The collections here listed were the first North American 
representatives of the genus seen by the writer, but they were 
followed almost immediately by a collection of Milesia Krie- 
geriana (Magn.) comb. nov. {Milesina Kriegeriana Magn.) on 
Aspidium marginale, from Hudson, Quebec, Canada, communi- 
cated by W. P. Fraser, who made the collection in June, 1913. 
Up to the present time the only other North American col- 
lection known to the writer, that should be placed in the genus, 
was found on a specimen of Dryopteris patens (Sw.) Kuntze in 
the fern collection of the N. Y. Bot. Garden, obtained at Whit- 
field Hall, Jamaica, 3,000 feet altitude, April 20, 1903, L. M. 
Underwood 2522. The species appears to be similar to M. Krie- 
gcriana, but sufficiently distinct to merit a separate name. It 
may be called Milesia consimilis sp. nov., and characterized by 
the ellipsoid or obovoid urediniospores, being 16-21 by 26-29 /x, 
with colorless wall, 2. 5-3. 5 /x thick, moderately to sparsely echinu- 
late with rather large points. The peridium is similar to that in 
M. Kriegeriana. 
I am using the genus name Milesia, as I believe it was properly 
established upon the most distinctive spore form that could have 
been selected (Cf. Science 40: 935. 1914), and that the re- 
christening by Magnus (Ber. Deut. Bot. Ges. 27: 325. 1909) 
was superfluous, although conforming to the ruling of the Brus- 
sels Congress.
