62 HERRE 



Specimens in the Tuck. Herb, were collected by Dr. W. G. Farlow 

 at Monterey, in August, 1885, growing on rocks. 



In the herbarium of Dr. C. L. Anderson of Santa Cruz, are several 

 specimens labelled Acolium farlowi which were collected by him on 

 shale about Santa Cruz. Probably some of these were identified by 

 either Tuckerman or Farlow and are therefore correct, but the one 

 now in my possession is Cyphelium bolanderi. 



Apparently very rare and local in its distribution. (Named in honor 

 of the eminent professor of cryptogamic botany at Harvard Univer- 

 sity, Dr. W. G. Farlow.) . 



6. CYPHELIUM OCCIDENTALS Herre, new species. 



Acolium sp. Hasse determ., in Baker, Pacific Coast Lichens, No. 



436, 1902; Stanford University. 



Thallus determinate, forming rounded or oval patches, or effuse 

 and spreading extensively; of rounded thick areoles, with their sur- 

 faces made up of many small rounded nodules, the whole forming a 

 chinky, deeply fissured crust of a whitish or ashy gray color; 

 KOH - ;CaCl 2 2 -. 



Apothecia innate in swollen warts, from small becoming medium 

 or large; disk black; the thickish, entire, white margin concealed by 

 the protruding spore mass, the surface of which with age often 

 becomes tinged more or less with green; the long slender paraphyses 

 broader than in the other members of the genus occurring with us; 

 thecium bounded basally by a very broad, sub-crescentic brown- 

 black band; asci rather slender, cylindrical; spores bilocular, strongly 



constricted at the middle, oblong-ellipsoid, - _ /< 



On old fences in the mountains and formerly in the foothills, but 

 the fences on which it occurred there some years ago have since been 

 replaced by wire fences. 



The protruding spore mass marks the fingers with black when 

 touched, as is also the case with some other members of the genus. 



7. CYPHELIUM ANDERSONI Herre, new species. 



Thallus orbicular, thickish, margin radiately crenate-lobed, fis- 

 sured crustaceous, the smooth surface plicate and rugulose con-
