On mossy sandstone and earth in the foothills; not rare. Orig- 

 inally described from specimens collected by Macoun on Vancouver 

 Island; recorded also by Professor Cummings from Alaska. No 

 other locaUties seem to be noted by any authors. 



My material agrees with the type specimens in the Tuckerman 

 herbarium. 



4. PARMELIELLA CYANOLEPRA (Tuck.) Herre. 



Pannaria cyanolepra Tuck. Lich. Calif. 17. 1866.

Thallus of minute, dissected, dusky yellowish or buff squamules, 

 their edges and soon the whole thallus disappearing under a con- 

 fused mass of minute, steel-blue granules; the plant ordinarily a 

 thin indeterminate, fragile blue crust, with but few or no squam- 

 ules visible. 



Apothecia minute to small, finally medium in size, closely ap- 

 pressed, plane, becoming convex and excluding the thin, entire, 

 erect proper margin; disk dark red to black red; epithecium yel- 

 lowish brown; thecium bluish with I; spores ellipsoid,

Not uncommon on clay banks and encrusting mosses beside roads 

 in the foothills and mountains, forming more or less conspicuous 

 patches. Usually sterile; fertile specimens collected but once, on 

 clay and broken rock, in Hidden Villa Canon, at an altitude of 800 

 feet. Fruiting specimens collected by Bolander near San Francisco 

 and on the American river, near Auburn. 



I have removed this from sub-specific to specific rank, in accord- 

 ance with Tuckerman's original idea.
