Critical Review of the Mycological System

Agaricus.

Ser. I. LEUCOSPORI, with white sporidia, more rarely only whitish (sordid).

I. AMANITA (S. M. 1. p. 12) Leucosporus. Universal veil originally contiguous or a volva universal veil remnant at base discrete from the epidermis of the pileus. Hymenophorum discrete from the stipe. All terrestrial. Cf. Hist. Soc. Roy. Medic. Par. 1776. Attention should be paid to the analogy of species in various sections!

A. With a manifest superior ring.

• Volva with an apically lacerate-dehiscent limb, persistent and free. The whole fungus originally enclosed within a similar volva, connate with the base of the stipe, but lying free. Pileus naked or sprinkled with wide, membranaceous, vague fragments of the volva.

1. A. CAESAREUS, pileus hemisphaerico-expanded, margin straight and striate, stipe subventricose floccose and cottony-stuffed, volva and ring loose, lamellae yellow. Scop. Carn. p. 419. Schaeff. IV. p. 64 (excellent, but the icon is fictitious) S. M. 1. p. 15. c. syn. Paul. Ch. t. 154. Kromb. Schw. t. 8. Vittadin. Fung. manger. t. 1. A. aurant. Bull. t. 120. In forests of temperate regions; in Europe as far as Bohemia. Most specious ("prince of fungi", commonly called Caesar's mushroom), celebrated from antiquity (Boletus of the Romans), most savory (food of the Gods, Clus. esc. gen. 17). Pileus orange, more rarely copper, red, yellow, even white with veils. Flesh turning yellowish upward.

2. A. COCCOLA, pileus ovato-expanded, margin incurved and sulcate, stipe cylindrical villose and cottony-stuffed, volva and ring loose, lamellae white. Scop. p. 429. — Batt. t. 4. D. In the Mediterranean region, hot America. Also delicious, entirely white or with a livid pileus. Different from the prior and the following! and especially from the "Coquenielle" Paul = Am alba Pers., which is a Volvaria.

3. A. OVOIDEUS, pileus hemisphaerico-expanded, margin exceeding and inflexed, smooth, stipe solid bulbous and squamulose-farinaceous, volva and ring loose, lamellae free and ventricose. Bull. t. 364. Vittad. t. 2. In forests of the Mediterranean region, also in Paris. Strong, robust, white, almost odorless, edible.

4. A. VIROSUS, pileus conico-expanded, glutinous (shiny), margin sublobate-repand and inflexed, smooth, stipe stuffed from a bulbous base, cylindrical and squamose-lacerate, volva thick and apical ring floccose-melting and loose, lamellae free and linear-lanceolate. Under Hyp. virosus Paul.; [Secr. n. 5 rather A. Phalloid.] Am. stram. Secr. n. 9. In forests, northern Europe and
