This is a common species in the Northern Hemisphere and also commonly
collected in lowland alien forests of the Hawaiian Islands.  Mature basidiomata are
indistinguishable from those of M. spinosissima  and M. brunneospinosa  (photos
provided elsewhere on this WWW page);  primordia are necessary for accurate species
diagnosis.  See Biblio. Mycol. 159: 1-89, 1995 for an accounting of the worldwide
