Major Vetiey. I am obliged to the gentleman just 
mentioned for the knowledge of ‘this plant being indige- ~ 
nous, for most of the preceding characters, and for the ; 
following observations :—The pileus is so little fleshy, 
that when dry, it is sufficiently transparent to exhibit the 
form of the gills. ‘The decurrence of the longer gills, 
which is invariable, separates it from the Ag. coriaceus 
of Lightfoot, (Ag, orcades) the gills of which, as he 
observes, do not touch the stem. Jt is much less fleshy 
than the Ag. eburneus. It cannot be Ray Syn. p. 7.
