an interesting fungus flora correlated with its unusual climatic 

 conditions. 



California. 



Commencing in the seventies Dr. H. W. Harkness and his as- 

 sistants collected extensively in the vicinity of San Francisco and 

 in the Sierras. The earlier collections were named by various 

 English mycologists, Cooke, Phillips, Plowright and Vize, so that 

 many of the types are in England ; those of Cooke are at Kew. 

 Duplicates of these, together with types of later species, are in the 

 California Academy of Sciences. Many duplicates from Harkness 

 are in the Ellis collection. Later collections have been made by 

 Farlow, Holway, Howe, Blasdale, McClatchie, Purpus, by the wri- 

 ter, and perhaps others who have either resided or traveled in the 

 state. Many of these later collections have found their way in 

 duplicate to the Ellis herbarium. A few, particularly fleshy forms 

 have been described by Peck, some by Morgan, and a few of the 

 Uredinales by Dietel. Probably not less than fifteen hundred 

 species have been reported from the State already, probably not 

 one-third of the number that will eventually be found to make 

 up its flora. The local literature bearing on Californian 

 fungi is correspondingly extensive ; the principal papers are the 

 following, but very many descriptions are scattered through other 

 publications with less restricted titles :

 102. 1879.
