would refer it to Cryptomitrium tenerum (Hook.) Aust. (p. 

 45), rather than to the Grimaldia. 



6. Asterella violacea (Aust.) Underw. (p. 53) 



In the opinion of the writer 7 this species is a synonym of 

 A. bolandcri (Aust.) Underw. 



7. Asterella gracilis (F. Web.) Underw. (p. 56) 



The writer 8 has recently discussed the synonymy of this 

 species and shown that it should bear the name A. ludivigii 

 ( Schwaegr. ) Underw. 



8. Lunularia cruciata (L.) Dumort. (p. 60) 



At the time Howe published his description of this intro- 

 duced species it was known in North America in a gemmi- 

 parous condition only. A few years later Miss Julia T. Shinn 9 

 announced the discovery of fruiting material at Niles, Cali- 

 fornia, and Mrs. Sutliffe, in the past year, has collected ad- 

 ditional fruiting specimens in Mill Valley, Marin County. 

 They grew, according to her label, "on damp banks beside 

 steps forming a street." 



9. Sphaerocarpos californicus Aust. (p. 65) 



Through the careful work of Miss Haynes 10 it has been 

 proved that this species is a synonym of 5. texanns Aust., 

 which antedates S. californicus by two years. 



10. Riccardia major Lindb. (p. 72) 



In accrediting R. major to California Howe compared the 

 species with R. pinnatiMa (Nees) Trevis. and stated that the 

 latter was distinguished by its "softer, flatter thallus, without 

 indication of a unistratose margin," by "its looser texture,"
