'This species differs from N. pediades and N. semi-orbicularis, to which 

 it is related, by its larger, broader spores and paler color. Peck, Bull. 

 Torr. Bot. Club, Vol. 25, No. 6. 



This new species reported from California is so closely allied to N. 

 semi-orbicularis and N. pediades, both of which are edible, that it is 

 here given, that it may be recognized by students on the Pacific coast 

 or wherever it occurs.
