GLAOCAPSA RUPESTRIS Awéz. 
What I take to be this species is not rare about Albany, 
forming a green stratum on stone steps, walls of buildings, 
old fences and trunks of trees. It is most conspicuous in 
wet weather in winter and spring. I have not seen a full 
description of the species. 
HYDROGASTRUM GRANULATUM ZL. 
Damp ground in dried water holes. North Greenbush. 
This plant has been supposed by some to be the cause of 
ague and has therefore been called the “ague plant,’’ but it 
is hardly probable that it has any such deleterious quality. 
SPIROGYRA LONGATA Vauch. 
In ditches along the railroad. North Greenbush. June.
