Observations: This also coiticolous variety, first described as an Usnea, 

 appears to be only a slender, though the commonest phase of the type, (due to 

 a latitudinal reduction) occurs throughout the range of the species and bears 

 commonly the capitate soralia referred to under ceruchis. The Abbe Hue re- 

 corded this slender phase from Laguna (Lich. Cal. 2. 1895), his plant being 

 slightly more slender than most of the material common to our area.

Observations: I have seen but one specimen of this rather questionable 

 species. It was collected at San Diego in 1882 by Dr. Ed. Palmer and is pre- 

 served in the Sullivant Moss Society herbarium (No. 349). The specimen is 

 longer than cited by Nylander and has wider spores, in all other particulars 

 agreeing with the original description.
