Vol. XIII] EVANS— HEPATIC Al OF CALIFORNIA \2\ 



13. Fossombronia pusilla (L.) Dumort. 



Stephani's record for California 22 was based on specimens 

 collected by Howe, no definite station being mentioned. These 

 particular specimens have not been available for study, but 

 the writer feels convinced that they must represent some form 

 of F. longiseta, probably a form in which the number of ridges 

 on the spores was relatively small. Spores of this character 

 are represented in Howe's fig. 18, drawn from a Mill Valley 

 specimen. Until it is definitely established that such spores 

 are associated with annual gametophytes, there seems to be no 

 conclusive reason why F. pusilla should be considered a mem- 

 ber of the Californian flora. In fact, the occurrence of the 

 species in North America is very doubtful, all the records (so 

 far as known) being based on sterile or incorrectly determined 

 specimens. 



14. Marsupella sullivantii (De Not.) Evans 



On rocks. Gold Lake, Plumas County, September, 1900, 

 J. B. Leiberg 5496. New to California; widely distributed 

 in northern countries and previously reported from Wash- 

 ington. 



15. Nardia crenulata (Sm.) Lindb. (p. 94) 



In the writer's opinion the true N. crenulata has not yet 

 been found in the western part of North America. It is re- 

 placed in the Pacific Coast region by the closely related N. 

 rubra (Gottsche) Evans, 23 a species which Howe included 

 among the synonyms of N. crenulata. 



16. Nardia obovata (Nees) Lindb. (p. 96) 



The writer feels convinced that the specimens from Blue 

 Lake, Humboldt County, upon which Howe's record was 

 based, represent J linger inannia sphcerocarpa Hook, or some 

 closely related species. 24 Unfortunately the specimens are too
