with that species. No Schweinitzian specimens of Sphaeria 
radicalis in this country, however, have yet been found which 
have ascospores, though there is no doubt from the specimen 
in the conidial stage in the Schweinitzian collection in the 
Philadelphia Academy of Science that S. radicalis refers either to 
this species or to E. gyrosa. As Shear had opportunity to see 
certain specimens of S. radicalis and S. gyrosa sent by 
Schweinitz to European botanists, the writer thought he had 
found the ascospores of S. radicalis to be linear. Recently 
writing Shear on this point, we received the following letter: 
“The specimens on oak roots collected by Hall in South 
Carolina which I identified as the typical S. radicalis of 
Schweinitz were, according to my recollection, compared with 
authentic specimens of Schweinitz from either Schweinitz’s 
herbarium or Curtis’ herbarium at Harvard. This identification 
was made last winter before my trip to Europe. I have been 
going over carefully all our slides and specimens to locate the 
material on which this identification was based. I regret to 
say that thus far I have been unable to find it. In this same 
connection I have examined very carefully the material from 
the Kew herbarium, which consists of an autograph specimen 
collected by Schweinitz, presumably at Salem, N. C., and sent 
by him to Hooker. I am surprised to find, on examination, 
that this specimen, though it shows considerable variation in 
ascospore measurements, does not appear to agree with the 
long, slender form of ascospores found in the specimen on oak 
roots which I sent you from Hall’s collection at Clemson 
College, S. C. The measurements, as they’ have just been made 
from a slide from the Kew specimen, range mostly from 6.3-8.6 
by 2.8-3.6 ». I think it is still possible that all sorts of inter- 
mediate forms and sizes of spores will be found in the South 
connecting the long and short-spored specimens.” 
Writing to the Kew herbarium for information concerning 
the specimen mentioned by Shear, which seems to be the only 
Schweinitzian ascospore specimen of Sphaeria radicalis yet 
reported, we received a letter from Assistant Director Hill, with 
the following notes made by E. M. Wakefield: “The specimen 
referred to by Shear appears to be one which bears simply a 
pasted-on rough paper label with the name ‘Sphaeria radicalis’ 
in ink. On the authority of Mr. C. G. Lloyd, who is working
