35. Halorhipis winstonii (Ands.) 



Plate XXVIII. 

 Punctaria winstonii Ands., Some New and Old Algae, Zoe IV, 1896, 358. 



Plant membranaceous, olive-brown, lanceolate, obovate, or spatulate, 8 

 cm. -2 dcm. long, 2-5 cm. broad, usually frayed and torn at the end, gradu- 

 ally narrowed below into a short stalk (2-8 mm. long). Unilocular sporangia 

 elliptical, obovate, or pyriform, 30-45// x 20-30//., sori numerous, forming 

 irregular, linear patches of various sizes. 



On Egregia nienziesii and on rocks at low tide level. 

 Carmelo Bay, California. 



In 1895 a study was made of material received from Dr. 

 Anderson, and the distinctness of this plant from Punctaria 

 was at once noticed. During the summer of 1896 several 

 trips were made to Carmelo Bay, fresh material in all stages 

 of growth was obtained from the same locality where the 

 type specimens were collected by Mr. Winston and sent to 

 Dr. Anderson. 



36. Phyllitis Kuetz. 



Phyllitis Kuetz., Phyc. Gener., 342, 1843. 



Plant body solid, membranaceous, lanceolate or linear, tapering toward 

 the base to a short round stem, of two layers of tissue, the cortical layer of 

 small cuboidal cells, the inner layer of oblong colorless cells. Unilocular 

 sporangia linear, covering the entire surface of the plant ; plurilocular spo- 

 rangia and paraphyses wanting. 



37. Phyllitis fascia {Muell.) Kuetz. 

 Plate XXX, Figs. 1-3. 



Phyllitis fascia (Muell.) Kuetz., 1. c 

 Fhcus fascia Oeder, F1. Dan. Tav., 768, 1761. 



Plant single or clustered, arising from a disk-like base, 2-30 cm. high, 1-5 

 cm. broad, linear, lanceolate, or elliptical, narrowed at base into a short 

 stem, or sessile. 



Two forms of this variable species have been collected 

 on the Calif ornian coast: 



A. — Plants gregarious, linear or oblanceolate, 3-15 cm. long, 3 mm. to 

 I cm. wide, gradually narrowed to a short stalk. 



On rocks and Phyllospadix sp. Monterey and Pacific 

 Grove, California.
