418 Rev. M.J. Berkeley and Rev. M. A. Curtis on new 



sated and rooting below, almost smooth with the exception of a 

 few little narrow transverse scales. Ring broad, evanescent. 

 Gills white, reaching the stem, qnite linear at the extremity. 

 Odour strong alkaline. 



A remarkably fine species, differing from A. nitidus in its 

 nearly smooth rooting stem, the base of which is much swollen, 

 but by no means margined. It resembles also A. Vittadini. 



2. Agaricus (iVmanita) monticulosus, n. s. Pileo convexo areo- 

 lato; verrucis marginalibus floccoso-pyramidatis, centralibus 

 pyramidatis truncatis ; stipite squamoso flocculento ; lamellis 

 liberis remotis. Ciu-t. no. 2829, 2853. In moist and sandy 

 woods, Sept., Nov., South Carolina. 



Pileus 2|^-3 inches across, convex, areolate, with a wart in the 

 centre of each areola ; those towards the margin consisting of 

 soft threads meeting in a point, but sometimes simply flocculent, 

 the central warts angular, pyramidal, truncate, discolom-ed. 

 Stem bulbous, scaly, flocculent, white; veil thick, at length 

 distant. Gills free, ventricose, remote, forming a well-defined 

 area round the top of the stem. 



The warts are not hard and rigid as in A. nitidus, and the free 

 remote gills separate it from that and the neighbouring species. 

 The specimen from a sandy wood has the characters far less 

 strongly marked than the others, in which the greater part of 

 the margin appears at first to be flocculent. 



3. A. (Lepiota) cultorum, n. s. Parvus ; pileo hemispherico 

 umbonato squamis granuliformibus exasperato ; stipite brevi fur- 

 furaceo, annulo subcentrali; lamellis latis remotis; sporis 

 utrinque acutiusculis. Curt. no. 2826. Among gourds in culti- 

 vated lands, July, South Cai'olina. 



Pileus 1 inch or more across, hemispherical, umbonate, the 

 border sometimes repand, clothed with very numerous brown 

 granular scales. Stem i-1 inch high, 1 line thick, furfuraceous. 

 Ring nearly central. Gills broad, ventricose, free, remote. Spores 

 cymbiform, rather acute at either extremity, about ^q^qq of an 

 inch long. 



A very pretty little species allied to A. cristatus, from which it 

 is readily known by its oblique spores which are nearly three 

 times as long. Perhaps it is really more closely allied to A. acute- 

 squamosus, AVeinm., which has far larger spores than A. cristatus, 

 though not so large as this species. 



4. Agaricus (Lepiota) floralis, Berk. & Rav. MSS. Pusillus, 

 pileo piano, squamis floccosis brunneis vestito ; margine striato ; 

 stipite gracili deorsum attenuato pileo concolore ; annulo medio 

 persistente; lamellis candidis tenuibus distantibus ventricosis 

 liberis. Rav. no. 1011. On earth in gardens, South Carolina, 

 July, H. W. Ravenel, Esq.
