Here described from two specimens collected on old redwood 

 boards near Santa Cruz, by Dr. C. L. Anderson. 



A very singular plant, with a thallus much like that of C. californi- 

 cum but with different apothecia, spores, and chemical reaction. 



I take pleasure in naming this for the veteran algologist of Santa 

 Cruz, colleague of Asa Gray and Tuckerman. 



SPH^ROPHORACEiE. 



We have but one genus of the family. 



XI. Sphaerophorus. 



Sphcerophorus Persoon in Ust. Ann. Bot. 7: 23. 1794.

 es; alga Protococcus. Apothecia terminal, in globose sweUings of 

 the tips of branches, which are at first closed and later open by an 

 irregular fissure at the tip.
