Recently upon opening- my mosses for examination this moss proves to 
be Paludella squarrosa (L.) Brid. of which I am unable to find any previous 
record for New England. I shall certainly get a larger quantity on my next 
visit. 
Specimens have been submitted to Mr. Chamberlain who verifies the 
determination, and to Mr. Collins who sends the following record of its 
collection : 
“ I find I have no record of any station for Paludella in New England. 
The record that I had in mind proves to be a New York record. Other 
records are Greenland, Hudson’s Bay, Mt. Albert and Gramd River (Gaspe), 
Anticosta, Rocky Mts. of Canada, British Columbia, Saskatchewan, Alaska, 
and near Montreal, Canada.” Auburndale, Mass. 
«‘THE LICHEN FLORA OF THE SANTA CRUZ PENINSULA. 
A REVIEW. 
Lincoln Ware Riddle. 
The appearance, within a period of less than a month, of two extensive 
and important papers on lichens is a sufficiently remarkable experience in 
North American Lichenology to call for special notice. Prof. Bruce Fink’s 
“Lichens of Minnesota,” which appeared June i, 1910, has already been 
reviewed in these pages. ^ And it now becomes the reviewer’s privilege to 
call to the attention of the readers of The Bryologist the work of Dr. A, C. 
Herre on “The Lichen Flora of the Santa Cruz Peninsula, California,” 
published May 15, 1910. ^ It is of interest to compare these two papers in a 
general way. Each represents the intensive study of a restricted region ; 
each author has published various preliminary studies,^ and in each case the 
present papers come as the culmination of prolonged work. Minnesota being 
the larger field offers 439 species and varieties, but the richness of the Cali- 
fornian flora results in the description of 309 species and varieties from the 
smaller area. 
Dr. Herre’s paper should be of special interest to American students as 
being the first important paper to embody consistently Dr. Zahlbruckner’s 
ideas of classification and nomenclature as presented in his treatment of the 
ichens in Engler and Prantl.^ After the long established authority of Tuck- 
erman’s “ Synopsis of the North American Lichens” to which we are accus- 
tomed this can not but seem radical. Yet it is undoubtedly the nearest 
approach that we yet have to a classification upon which the majority of
