ToRULA POPULINA 7. sp. 
June. 
Spore threads aggregated in minute tufts, situated on the under 
surface of the leaf, on arid, orbicular, distinct or sub-confiuent 
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 -

Fronds of Phegopteris Dryopteris. Catskill mountains. July.

has subglobose spores and the sori occur on the under surface of 
the frond. 
Urepo Aicrpro1pEs 7. sp. 
Spots obliterated, sori amphigenous, bullate, small, scattered or
