I cannot reconcile myself to identifying this liclien with A. 

 cinnabarina var : anerythrea. (Nyl.) The loculi of the spores 

 are nearly of the same size, and certainly not larger at either 

 extremity. No septa properly so called have been detected, 

 although the loculi are at times in close apposition, &c. 



The next two are descriptions of lichens picked out of a small 

 parcel sent by Mr. D. A. P. Watt, who secured them in the 

 neighbourhood of Montreal, Canada.
