the discomycetes (Histoire et classification des Discomycètes d'Europe, 

 Paris 1907) Boudier retains this species under the genus Geopyxis. 

 When in his genus-diagnose he claims that asci must not be dyed blue 

 by iodine, it cannot be upheld with regard to this species. 



The fungus, originally described from Algeria, is further known 

 from England and France "immersa in sabulosis ad radices Psammae" 

 or amongst Elymus.
