Agaricus rhacodes Vitt. Descr. Funghi Mang. 158. 1835. 



Pileus fleshy, soft, globose to expanded or depressed, usually cespitose, 7-10 cm. broad; 

 surface dry, smooth, and brown when young, becoming very coarsely scaly except at the 

 center from the breaking up of the cuticle; context white, becoming brownish-orange on 

 exposure; lamellae free, remote, white; spores ovoid-ellipsoid, hyaline, 9-12X7-9 p.; stipe stout, 

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

 annulus ample, fixed, becoming movable, edge of veil double and fringed. 



Type locality: Italy. 



Habitat: Rich soil in gardens and greenhouses. 

 Distribution: Massachusetts; also in Europe.

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 Massee 

 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. 5: 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. 1921. American plants referred to this 

 species by the older mycologists are only forms of L. cretacea. 



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. 



1. Chlorophyllum Molybdites Mass. Kew Bull. 1898: 136. 1898. 



Agaricus Molybdites G. Meyer, Fl. Esseq. 300. 1818. 



Pholiota Glaziovii Berk, in Warming, Vidensk. Meddel. 1879-80: 32. 1879. 



Agaricus Morgani Peck, Bot. Gaz. 4: 137. 1879. 



Lepiota ochrospora Cooke & Mass. Grevillea 21: 73. 1893. 



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
