This abundant fungus presents such peculiar spore characters 

 that it is not remarkable that its generic relationship has been mis- 

 understood. When young the sporidia are hyaline, and are dis- 

 tinctly 3- or sometimes 5-septate. At maturity they become dark 

 brown and densely opaque so that the septa are not visible. They 

 are somewhat constricted at the middle septum, which gives the 

 '"ature sporidium the effect of being only 2 -celled as it has been 

 always heretofore described. With careful illumination the addi- 

 tional septa can be seen after the spore has become quite darkly 

 colored, but at full maturity they are completely obscured. In all 

 ot her respects Atkinson's description is full and satisfactory. He 

 ls doubtless correct in referring our Alabama material as above, 

 though Berkeley's remark (Grev. 4 : 145) that " There is another 

 distinct species on Arundinaria from Alabama, but indescribable 

 without sporidia," suggests the possibility of an error. Atkinson 

 do <-'s not quote Massee's examination of the type except as to the 

 c "'or of the spores.
