and in the ability to judge concerning the value of their characters 
and their proper classification; second, the unnecessary multiplica- 
tion of genera founded on slight differences is to be deprecated. 
Boxerus retires B. & C. Report 23, p. 182. 
As soon as the characters of this species were published by Rev. 
M. J. Berkeley, it became evident that the plant I had hesitatingly 
referred to it and described in the location cited was distinct. There 
is no pulverulence to our plant nor does it have “ pilei arising from 
a common base.” I would, therefore, give it the name Boletus orna- 
tipes. Kither this or a closely related form is regarded by my friend, 
Mr. C. C. Frost, as a variety of B. griseus, but the yellow flesh and 
the tubes, which are also yellow from the first, indicate to my mind 
a specitic difference. It is by having respect to such a difference in 
color that the whole genus has been divided into primary series, and 
it hardly seems fitting to throw together, as varieties of one species, © 
forms thus separated. 
THELEPHORA PALLIDA Schw. 
This name, being preoccupied, must be changed. I would substi- 
tute for it, Zhelephora Schweinitzi. 
Pocornta Trarettez 6. & C. Report 25, p. 115. 
Since the publication of this species, for the authenticity of which 
I depended upon specimens received from the late Dr. Curtis, Rev. 
Dr. Berkeley has published in Grevillea, 1874, p. 53, under the same 
name, a species which is clearly quite different. He also finds Pweci- 
nia Saxifragarum on Tiarella leaves. Neither can this be our plant, 
for P. Saxifragarum has its spores much broader and more obtuse. 
In view, therefore, of the peculiar circumstances attending the publi- 
cation of these two species under the same name, I deem it the most 
courteous, if not the most correct way, to drop the name P. Tiarelle 
from its connection with the plant described in the 25th Report, and 
substitute for it the name Puccinia spreta Pk., thus leaving P. 
Tiarelle B. & C. tor. the species to which it has been applied by Dr. 
Berkeley. .

Some account of the synonymy of this species seems desirable. In 
the synopsis of the Fungi of North Carolina, Dr. Schweinitz describes 
a fungus under the name Uredo Caladii, giving Caladium as its 
habitat. In his Synopsis of North American Fungi, he changes the 
name of this fungus to Uredo Ari-Virginici, adding the remark, 
perhaps as a reason for the change, “it is not Caladium but Arum on 
which it is found frequently.” This remark admits of two interpre- 
tations depending upon the stress given to the last word. He may 
have found the fungus at first on Caladium and afterwards more fre- 
quently on Arum, or he may at first have mistaken the host plant, 
Arum, for Caladium, in which case the remark must have been
