group was published in 1920 32 and has been of great help to 

 the writer in determining the Californian material. Howe's 

 "Cephalozia divaricata" is listed below (at least in part) under 

 the name Cephaloziella byssacea, while his var. scabra (p. 129) 

 is regarded as a synonym of C. papulosa. Two other species 

 are reported for the first time from the state, and a fifth 

 species, C. palulifolia, although unknown to the writer, is 

 briefly alluded to.

Without definite localities, H. N. Bolander (several speci- 

 mens) ; "Mission Hills," H. N. Bolander; Yosemite Valley,
