smooth, hollow, white, strongly bulbous at the base, about 8-10 cm. long and 2 cm. thick;

DOUBTFUL SPECIES
Lepiota asprata (Berk.) Sacc. Syll. Fung. 5: 48.' 1887. Described from Ceylon, oc- •
curring there on the ground; and later described from New Caledonia by Cooke and Massée
as Agaricus (Lepiota) echinodermatus. Specimens distributed by Ravenel from, South Caro-
lina, occurring on dead branches, have the same general appearance as the Ceylon plants but
are probably different.
Lepiota Badhami (Berk.) Sacc. Syll. Fung. S: 35. 1887. The older mycologists doubtless
confused L. americana Peck with this species.
Agaricus felinus Pers. Syn. Fung. 261. 1801. A very slender European species much
like L. conspurcata in form, the surface white with blackish disk and concentric rows of scales.
The plants formerly referred to this species in America probably belong to L. fuscosquamea
Peck.
Agaricus mastoideus Fries, Syst. Myc. 1: 20. 1821. American plants referred to this
species by the older mycologists are only forms of L. cretácea.
Agaricus meleagris Sow. Engl. Fungi pi. 171. 1798. This species has several times been
reported from North America, probably having been confused with L. brunnescens Peck.
Agaricus metulaesporus Berk. & Br. Described from Ceylon and often confused with
L. clypeolaria, of which it may be a form.
Agaricus xylogenus Mont. Syll. Crypt. 122. 1856. Described from plants collected by
Sullivant near Columbus, Ohio. See note in Mycologia 6: 151. 1914.
49. CHLOROPHYLLUM Mass. Kew Bull. 1898: 135. 1898.
Pileus soft, fleshy, putrescent, not viscid, squamulose; lamellae free, white, colored green
by the spores at maturity; spores green; annulus persistent, movable; stipe bulbous; volva
none.
Type species, Chlorophyllum esculentum Mass.

Agaricus Molybdites G. Meyer, Fl. Esseq. 300. 1818.
Pholiota Glaziovii Berk, in Warming, Vidensk. Meddel. 1879-80: 32. 1879.

Chlorophyllum esculentum Mass. Kew Bull. 1898: 136. 1898.
Agaricus guadelupensis Pat. Bull. Soc. Myc. Fr. 15: 197. 1899.
Pileus fleshy, at first globose then convex and expanded or depressed, gregarious or in
rings, 10-20 cm. broad; surface white beneath the cuticle, radiate-fibrillose, the cuticle at first
continuous, buff to pale-umber, soon broken up, except in the center, into irregular scales and
