jDlane, with a trace of an umbo, striate, pulverulent, whitish, 

 disc more or less tinged with brown; gills free or veiy 

 slightly adnexed at first, rather distant, about 1 line broart, 

 white ; stem about 1 J in. long, 1 line thick, slightly striate, 

 hollow ; spores white, smooth, 6 X 4 /i.

In a stove at Kew. 



Undoubtedly an introduced species, and in all probability 

 an Australian species, as I have seen specimens from Queens- 

 land that agree exactly with Berkeley's type. In Queenslanil 

 it is said to be luminous, emitting a greenish light. 



LEPIOTA. Fries, (figs. 6, 7, p. 3.) 



Pileus regular, usually scaly, due to the presence of the 

 concrete universal veil and the breaking up of the cuticle ; 

 gills free, often very remote from the stem and attached to 

 a Cartilaginous collar, stem central, its substance distinct 

 from the flesh of the pileus; ring atfiist continuous with 

 the cuticle of the pileus, often movable, sometimes soon 

 disappearing; voU'a absent. 



Lepiota, Fries, Syst. Myc, i. p. 19; Cke., Hdbk., p. 11 (as 

 a subgenus of Agaricus). 



The present genus differs from Amanita and Amanitopsis in 

 the absence of a volva, and from every other genus in the 

 Leucosporeae in the free gills. 



In many species^but not in all — the flesh of the stemi 

 is of a difierent texture to that of the pileus, and its apex, 

 terminates in a socket-like depression of the flesh of the 

 pileus, a peculiarity clearly evident in a vertical section 

 through pileus and stem. The remains of the imiveroall 

 veil is thoroughly connate with the cuticle or the pileus, and 

 not in the form of removable warts or flakes as in Amanita 

 and Amanitopsis. 



The species grow on the ground ; several are met with 

 in hothouses, melon beds, &c., and are in all probability 

 introduced species.
