﻿366 Earle : New or Noteworthy 



The prominent perithecia give this at first sight the look of an 

 Hysterium rather than that of a Lophoderminm. In the numerous 

 specimens examined the asci were all in rather poor condition and 

 the spore characters were difficult to make out. The paraphyses, 

 if present, were so agglutinated as to be indistinguishable. 



Cercospora gnaphaliacea Cooke (?). 



Spots none : hyphae collected in dense fascicles arising from a 

 stromatic base, fascicles thickly scattered over considerable areas 

 which they discolor, hyphae long, weak and flexed, but sparingly 

 or not at all dentate, occasionally septate, in the dried specimens 

 seemingly flattened and twisted, olivaceous, 100-200 or more 



b 7 4-5 : conidia, straight, cylindrical, 3-septate, granular, hya- 

 line, about 40-50 x 5-6 u. 



On Gnaphalium purpurmm, Auburn, Ala., February 21, 1897. 

 Earle & Baker. 



This is a peculiar species and it departs quite widely from the 

 usual type of the genus. In general appearance it somewhat re- 

 sembles Scolecotrichum Euphorbiae Tracy & Earle, on Euphorbia. 



It is impossible to decide from Cooke's brief description whether 

 or not this is the same as the Texas fungus collected by Ravenel. 

 As the probabilities seem to lie in that direction it is provisionally 

 so determined. 



Cercospora ompiiacodes Ell. & Holw. 



On Phlox metadata Chambers County, Alabama, June 22. 

 1897. F. S. Earle. 



Our specimens show no distinct spotting of the leaves such as 

 is found in Canadian specimens on Phlox divaricate, N. A. F. 2975> 

 and Louisiana specimens on P. paniculata, Langlois, no. I3 6 5- 

 The hyphae are hypophyllous and effused over considerable areas 

 forming a cinnamon-brown coating. The leaf is only slightly dis- 

 colored above. The spores and hyphae are much as in the other 

 specimens mentioned, though the latter are perhaps less closely 

 fascicled, and somewhat longer in the Alabama form. It should 

 be noted that these specimens were taken in deep shady woods. 



Cercospora Ribjs sp. nov. 



Spots definite, orbicular or irregular, 1-3 or 4 mm., white above, 

 brown below, with dark brown narrow border : hyphae hypop J,vI "
