The gills are composed of a double membrane, and are simple or branched. No type in the vegetable world has shown greater diversity of form. Genus I.—Agaricus L. (The name is said to be derived from Agaria, a region of Sar- matia.)—The following are the distinguishing features of this large genus : Gills membranaceous, scissile, acute at the edge, persistent, concrete by the somewhat floccose trama with the inferior hymenophore. Veil various, but never in the form of a spider-web when universal. Spores separating from the sporo- phores, and falling off, hence the gills are not cinnamon-pulver- ulent as in the Cortinarii. Fleshy or j?tenibra?iaceoiis, putrescent ajid not revivi7ig when once dried 2ip. Fr. Hyin. Fur. p. 17. The genus Agaricus is divided into five series, which are de- termined by the colour of the spores. These are white, pink, brown, purple, and black. The white-spored species are the high- est in type, being firmer and more persistent than those which have coloured spores. In these last there is a greater tendency to deliquesce, especially in the case of the black-spored Agarics. Series I. LEUCOSPORI (Xew/cd?, white, aTrSpos, seed). Spores white, rarely whitish (dingy or inclining to reddish), globose, ovate or oblong, simple, even, very rarely rough. Fr. Hyni. E2ir. p. 17. Subgenus I. AMANITA (a name given to some esculent fungi by Galen, perhaps from Mount Amanus.) Fr. Syst. Myc. i. p. 12. Universal veil {volvd) which is at first continuous (completely enveloping the young plant) distinct from the epidermis of the pileus. Hymenophore distinct from the stem. All growing o?i the ground. Fr. Hy?n. Eur. p. 17. Some of the Amanitas are edible, others very /. Aga ricus (A ma nit a) in nscariits. One-quarter natural size. A. Ring manifest, superior. * V
