distinct species or may be only a geographical variety of the 

 Iowa species. 



The genus Sphaerozone Zobel should include 4he brown- 

 verrucose-spored species, Sphaer ozone ostiolatum (Tal.) Setchell. 

 The new combination is published by Setchell, since,%lthough the 

 genus was based on this species, it was included by Zobel under 

 the name Sphaerozone Tulasnei. 



The genus Ruhlandiella was described by Hennings and , based 

 on a brown-reticulate-spored species, and, as stated above, was 

 thought by Hennings to be closely related to Sphaerosoma. The 

 Californian specimens are made the basis of a new species belong- 

 ing to this genus, which is published by Setchell under the name 

 Ruhlandiella hesperia. 



From his study of the specimens of Sphaerosoma (in its re- 

 stricted sense), Setchell believes that the plants of the genus are 

 hemicleistocarpous and therefore belong more properly with the 

 Pezizineae than with the Helvellineae, as has formerly been 

 thought, and, since the plants have a weakly developed peridium, 

 he suggests a possible relationship with the Pyronemaceae rather 

 than with the Pezizaceae — F. J. Seaver.
