REPORT OF THE BOTANIST. OL 
The sori sometimes occupy the whole under surface of the leaf. 
Their black color contrasts beautifully with the light color of the 
spot. 
PUcvINIA TRIPUSTULATA 2.’ Sp. 
Spots very small, angular, distinct, yellowish ; sori hypogenons, 
few, distinct; spores broadly ovate or sub-triangular, tripustulate, 
scarcely constricted, brown, 74,’ long, about ;;/5y’ in diameter ; 
pedicel short or obsolete. 
Under surface of leaves of the blackberry, Rubus villosus. 
Greig. September. (Plate 3, figs. 14-16.) 
A remarkably distinct species. There are usually from one to 
five sori on each spot. There are three prominent points or angles 
to each spore, one at the apex, two at the base of the spore. To 
one of the latter points the pedicel is attached. The other is 
sometimes considerably removed from its neighbor, so that it 
appears to be almost lateral. A little pellucid pustule usually 
crowns these points, and sometimes two may be seen on the apical 
prominence. 
PouccInIaA MINUTULA 7. sp. 
Spots suborbicular, scattered or confluent, yellow, with a purple 
or brown center; sori situated on the center of the spot, very 
small, crowded, black, covered by the epidermis; spores oblong, 
acute or acuminate, rarely obtuse, slightly constricted, 74,/~1;' 
long; pedicel generally shorter than the spore. 
Under surface of leaves of Solidago altissima. Catskill moun- 
tains. July. 
The sori under a lens look like some small Spheria. Allied to 
P. virgauree. 
PoucorntA GERARDII 72. sp. : 
Spots orbicular, distinct or sub-confluent, yellow, depressed 
above, bullate below ; sori crowded, matted together, or confluent, 
tawny or amber-brown; spores oblong-clavate, distinctly constric- 
ted, obtuse, ++,’ long, pedicel nearly as long as the spore. 
Under surface of leaves of Aster simplex. Poughkeepsie. 
Gerard. Greenbush. July. 
The different color and matted appearance of the sori separate 
this species from P. Asterzs Schw.. Sometimes the sori are quite 
plentiful on the superior surface of the leaf.
