F. echinata Macvicar, 18 based on material from Algeria, 

 Dalmatia and southern Italy and since reported by Casares 

 Gil from Spain. 19 In this species the spores are described as 

 densely hispid, the individual projections being 2-4n long 

 and acute or subacute at the tips. No intimation is made in 

 the published descriptions that any of the projections are ever 

 in the form of ridges, so that Macvicar's species must show 

 the echinate condition in an especially typical way.

"California", without definite locality, H. N. Bolander 

 (distributed in Austin's Hep. Bor.-Amer. No. 118); Mill 

 Valley, Marin County, M. A. Howe (distributed in Under- 

 wood & Cook's Hep. Amer. No. 157); same locality, Mrs. 

 Sutliffe (a series of specimens) ; Mt. Tamalpais, Marin 

 County, M. A. Howe 6; Yosemite Valley, Mariposa County, 

 A. W. Evans; lone, Amador County, Miss Alice Eastwood; 

 Spencer Valley, San Diego County, L. Abrams 3800; Clare- 

 most, Los Angeles County, P. A. Munz 4727. This list is 

 based on the specimens in the Yale Herbarium; Howe gives 

 several additional localities for the species, but it is possible 

 that some of his records are based on what is here called F. 

 hispidissima. Outside of California the only station for F. 

 longiseta known to the writer is Cherry Creek, Santa Catalina 

 Mountains, Arizona, G. E. Nichols. 20 



The segregation of F. hispidissima as a species leaves a 

 residue of California Fossombroniae in which the spores con- 

 form to the cristate type. Unfortunately, these cristate spores 

 vary markedly in the number of ridges that they show, this 

 number being most conveniently estimated for comparative 

 purposes by counting the projections at the periphery of the 

 spherical face. In the specimens distributed by Austin in his 

 Hepaticae Boreali-Americanae there are usually from 22 to 26 

 of these projections. Since these spore-bearing specimens were 

 issued by Austin himself they may well be regarded as au- 

 thentic representatives of F. longiseta, especially in the ab- 

 sence of an actual type specimen, to which Howe calls
