Leaves of Lobelia svioata. ISTassau, Rensselaer coimty. June. 

 The spots are generally l"-2" in diameter. The colored margin 

 is usually paler as it recedes from the spot. 



Cytispoka melasperma Ft. 



Dead branches of birches. Sandlake. May. 



Cytispora parva B. (& C. 



J) e?id hranches of liohinia pseudacacia. Garrisons. June.

TORULA POPULINA 71. Sp. 



Spore threads aggregated in minute tufts, situated on the under 

 surface of the leaf, on arid, orbicular, distinct or sub-coniluent 

 brown spots, with one to three strictures, breaking up into oblong- 

 elliptical, subacute spores. 



Leaves of Populus grandidentata. Luzerne, Warren county. 

 June. 



The spots have a dark, well defined margin and a reddish-brown

 confluent; sori small, rotund, a little elevated, one to three on each 

 spot, on the upper surface of the frond ; spores yellow, ovate or 

 pyriform, -g-J-g-' long, a little more than half as wide. 



Fronds of Phegopteris Dryopteris. Catskill mountains. July. 

 (Plate 1, figs. 18-20.) 



At a little distance the fronds on which this fungus grows appear 

 as if infested by a yellow scale insect, so exactly do the spots 

 resemble the shape of some species of Aspidiotiis. TJ. Filicum 

 has subglobose spores and the sori occur on the under surface of 

 the frond. 



Uredo ^cidioides n. sp. 



Spots obliterated, sori amphigenous, bull ate, small, scattered or 

 close ; spores globose, at first covered by the epidermis, then sur-
