256 The North American Cup-Fungi 



These additional specimens have materially extended the range 

 of the species northward. 



Excluded Genus 



Spragueola Massee, Jour. Bot. 34: 149. 1896. This genus was founded 

 by Massee on Spragueola americana, which according to Durand is Mitrula 

 irregularis (Peck) Durand, a species which becomes irregularly distorted as 

 indicated by its name. 



BIBLIOGRAPHICAL NOTE 



Since most of the citations in this work are familiar to 

 mycologists, it hardly seems necessary at this time to append a 

 complete bibliography. If a second volume is eventually pub- 

 lished on the Inoperculates, it would be much more fitting that 

 the bibliography, if one is thought necessary, should appear at 

 that time.
