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 Queensland 

 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 - f 

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

 si cartilaginous collar, stem central, its substance distinct 

 from the flesh of the pileus ; ring at first continuous with 

 the cuticle of the pileus, often movable, sometimes soon, 

 disappearing; volva 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 

 Ihe absence of a vulva, and from every other genus in the 

 Leucosporeae in the free gills. 



In many species but not in all the flesh of the stem 

 is of a different 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 universal 

 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.
