.52 ERYTHEA. 



luens of this number were examined, both from the writer's own 

 copy and from the copy in Herb. Farlow. The plant distributed 

 is undoubtedly a Cylindrosperinum. No ripe spores were seen 

 attached, but many were intermixed in the material. They were 

 the eiiaraeteristic rough spores of C. majus as were also the attached, 

 unripe but still ventricose spores. C. majus has been distributed 

 from Connecticut by Holden (cf. Phyc. Bor.-Amer,, No. lOfi) and 

 has been collected in California by a number of people. 



Cylindrospermum licheniforme (Bory) Kuetz. occurred to the 

 writer, growing upon a bank within reach of salt spray, at Boliuas, 

 Marin County, California. The determination was kindly con- 

 firmed b}' Dr. Bornet. It has been credited to North America 

 heretofore, only from New York. (cf. Atkinson, Phyc. Bor.-Amer., 

 No. 309.) 



Schizothriz Mulleri Nreg. was credited to the United States on 

 authority of a specimen in Herb. Thuret, collected by Farlow. 

 Since then, it has been found at Saugus, Mass., by Collins (cf. Phyc. 

 Bor.-Amer., No. 7) and at Mount Carmel, Conn., by the writer. It 

 was also found, growing in considerable abundance, along the banks 

 of a small stream on Howell Mt., near St. Helena, Napa County, 

 California, by the writer, in February, 189o. The latter specimens 

 recall those of the Abbe Hy, mentioned by Gomont in a note 

 appended to the description of the species in his Monograph. In 

 some parts of the material, all the trichomes are solitary in the 

 sheaths, while the sheaths themselves are colorless or light yellow, 

 thin and papery, and seldom showing even a trace of stratification. 

 In other parts of the specimen, however, the typical form of the 

 species is met with. The trichomes have exactly the same char- 

 acteristics as regards shape of cell, terminal cell, etc., but the sheaths 

 are all gelatinous, strntose, and of the normal golden yellow color. 

 The thin, colorless sheaths gave no blue reaction with Chlor-Zinc 

 Iodine and the gelatinous sheaths turned blue only after some time 

 and even then faintly and without uniformity. 



Mlcrocoleus lacitstrls (Rab.) Farlow was known to Gomont, only 

 from Newton, Mass., where it was collected by Farlow. HoMen 

 has since collected it in Connecticut (cf. Phyc. Bor.-Amer., No, 307), 

 and it has been distributed by WoUe under the name of Phormidlum
