Since this manuscript was submitted to the printers, the 

 writer has received from Dr. John Axel Nannfeldt of Sweden 

 a collection, under the name of Sepultaria sepulta (Fries) Rehm, 

 which he reports growing abundantly on (or rather in or under) 

 the sidewalks in a suburb of Upsala just outside the Botanical 

 Garden and only a few hundred meters from the type locality. 

 He also states that it looks very insignificant like holes from 

 earthworms. 



Nannfeldt also states that after examination of the authentic 

 specimens of Peziza arenosa Fuckel, he is convinced that this is 

 identical with the above. Sepultaria arenosa has been treated 

 as distinct in this work, the American specimens referred to this 

 species having smaller apothecia which are only partially sub- 

 merged. It is possible that this is only a form of Sepultaria 

 arenicola.

Apothecia densely gregarious or cespitose, at first closed and 

 entirely buried, finally opening to the surface by an elongated or 

 compressed aperture, or when the substratum is not too compact 

 spreading so as to expose the hymenium, never protruding above 

 the surface of the substratum but causing the soil to become
