AMANITA MARMORATA SUBSP MYRTACEARUM - A NEW SUBSPECIES IN AMANITA SECTION PHALLOIDEAE FROM HAWAII

A widely distributed Amanita was observed on six of the Hawaiian Islan ds fruiting in association with Eucalyptus and Casuarina species. Subs equent investigation revealed it to be closely related to A. marmorata subsp. marmorata. The holotype of A. marmorata was studied and found to be badly molded and mostly destroyed. Some anatomical details were visible and, though it is similar to our material, there are anatomica l differences. The Haiwaiian populations are also quite variable macro scopically and anatomically and, as a result, a new subspecies, A. mar morata subsp. myrtacearum, is described for the Hawaiian Islands. A th ird taxon in this complex, A. reidii, recently described from South Af rica, is discussed.
