 change could be noted. The seven bundles along the line of

A MANUAL OF CALIFORNIA LICHENS. 

 By Bruce Fink. 



Beginning with Menzies (1792), a nu;".ber of botanists have 

 aided in collecting the California lichens. Other collectors are 

 Farlow, Cun-.?r.ings, Hasse, and Herre. These workers have 

 also studied the plants collected, and Tucker "an, Nylander, 

 Stizenberger and Zahlbruckner have also exa^ ined nearly all 

 of the species. Finally we have in Dr. Herre's ^"anual * a val- 

 uable treatise on the lichen flora of a portion of the state. The 

 Santa Cruz peninsula is only about 90 miles long and averages 

 about 25 miles wide, but 307 species and sub-species are des- 

 scribed in the manual, which will be found indispensable in the 

 study of the lichens of other portions of western North America. 



Though an excellent contribution, this Manual contains 

 certain faults w^hich are m.ore or less frequent in similar works 

 on lichens. We lichenists are all given to citing titles of large 

 separates instead of the place of original publication. The fol- 

 lowing three instances fro.n Dr. Herre's work will serve to il- 

 lustrate: Wainio Act. Soc. Faun. Flor. Fenn., cited Wainio 

 Mon. Clad. Univ.; Nyl. Mem. Soc. Sci. Nat. Cherb. 5, cited Nyl. 

 Enum. gen. Lich. ; and Fries, Th. M. Nov. Act Soc. Sci. Ups. 

 Ill, 3, cited Fries, Th. M. Lich. Arc. "A. Zahlb. Ascolichenes" 

 is also an incorrect form often used in the manual. It is easier 

 to find the journals in large libraries, and botanists are not usually 

 acquainted with these excerpts. Consequently the practice of 

 citing them should be abandoned, unless in parentheses with 

 the place of original publication. 



There is occasional lack of uniformity in citation as Ust. 

 Ann. Bot., on pages 63 and 6.5; Tuck. Gen. Lich., on pages 93
