| discussion |
So far as we know no collection of this
species exists. The original description is based on a watercolor by Gay. The absence of a striate margin is specifically noted by the author. That and the bulbous stipe and the limbate, rather than saccate, volva eliminate the possibility of placement in section Vaginatae which the original author also observes. The strongest case for sectional placement is in section Phalloideae and A. gayana does bare some similarity to the recently described species A. aurantiobrunnea
Simmons et al. (2002) from Guyana. The latter differs at least by having white gills, the presence of short gills, a weakly structured ring at the top of the stem, and an orange tint on the outside of the volval limb. Gay's records indicate this species named for him was not eaten in the area of Chile where it was originally collected.—R. E. Tulloss and E. Horak |
