I and III occur together on the same leaf. The spermogonia were 
not observed. Possiby the JEcidium may be JEcid. monoicum , Pk., 
but the color of the spores is different and the cups are open almost 
from the first. The manner of growth is the same. 
NOTES ON CERTAIN UREDINE^ AND USTILAGINE/E. 
By F. W. Anderson. 
^Ecidium crassum, Pers., JEcidium rharnni , Pers., and JEcidium 
pulcherrimum, Bavenel, are identical, and are considered to be I of Puc- 
cinia coronata , Corda. In Sacc. Sylloge JEcidium pulcherrimum is 
retained, probably inadvertently, in specific rank, although it plainly 
belongs as above. No. 933 of de Thiimen’s Mycotheca Universalis, 
given as JEcidium rliamni , Persoou, is identical with Kavenel’s speci¬ 
men of JEcidiuJn pulcherrimum. 
Number 1003 of Ellis’s N. A. F. is JEcidium ranunculacearum , DO. 
But h of this number is JEcidium ranunculi , of Schweinitz. The most 
available, and as it appears to me fairly constant, points of distinction 
between these two species are as follows: JEcidium ranunculacearum: 
teeidia always in spots, preceded or accompanied by the spermogonia 
which are aggregated usually in the center of the mcidium spots. 
JEcidium ranunculi , Schweinitz: tecidia always effused, preceded or 
accompanied by the spermogonia, which are also effused and scattered, 
like the secidia, indiscriminately over the surface of the leaf. Some¬ 
times the leaf is thickly covered by the fungus and again it may 
bear only a cup here and there. The form of JEcidium ranuncula¬ 
cearum on Ranunculus Cymhalaria , so common at the West, at times 
shows some inclination to approach JEcidium ranunculi in its manner 
of growth, but after all never seems to lose entirely its specific char¬ 
acters. 
AEcidium album, Clinton, in 26th Keport of the New r York State 
Museum for 1874 and JEcidium porosum , Peck, in Botanical Gazette, 
page 34,1878, are identical. The two supposed species occur on the same 
host plants, and have constantly the same manner of growth from New 
York State to the Pacific Ocean. Herewith is given an amended descrip¬ 
tion of this species: Spots none, cups few and scattered and almost 
superficial, or much crowded, in which case they appear to be deep-seated 
and give a porous appearance to the leaf surface; occupying a part or 
the whole of the lower surface of the leaves; frequently appearing on 
the stems also, in which situation they are hemispherical, or short-cy¬ 
lindrical, erumpent, and opening by a small, irregular, or roundish ori¬ 
fice. Spores from a bright orange color to almost colorless, very vari¬ 
able in this respect, subangular or roundish, oblong, oval or ovate, ac¬ 
cording to the free or crowded condition of the cups, 18// to 26// diame¬ 
ter. Saccardo in Sylloge, vol. 4, p. 787, says that P. porosum is distinct 
from P. album, but this can not be so.
