BRITISH MYCOLOGY. 
Under this heading it is proposed, in the first instance, to give 
descriptions of fungi added to the British list, since the cessation of 
the publication of “‘Grevillea.” A start im this direction <6 now 
made, but space prevents the incorporation of all species recorded 
since the date above indicated. This list will be continued next 
year, and the co-operation of all Mycologists is solicited for the 
purpose of furnishing a complete record. In addition, notes relating 
to subjects dealing with the work of British Mycologists will find a 
place. 
Lepiota leucothites Vitt., Fung. Wlang. 3160, pl 40. Pileus 
globose, then expanding until almost plane, more or less umbonate, 
glabrous and silky at first, becoming broken up into squamules, 
especially near the margin, during expansion, white, sometimes with 
a tinge of brown or ochraceous at the disc, 5-10 cm. across; flesh 
rather thick, white, unchangeable. Gills free, but rather close to 
the stem, crowded, thin, rather broad, often wavy, white at first, 
becoming pale pink with age. Spores elliptical, smooth, hyaline, 
9X 7m. Stem, 7-12 cm. long, base bulbous, subcylindrical above, 
1°5-2 cm. thick, differentiated from the flesh of the pileus, hollow, 
glabrous, white ; ring large, white, persistent, superior. 
On the ground. Herbarium Grounds, Kew; Isleworth, Surrey 
(G.M.); Malvern Hills (Rea). 
Probably not uncommon, but hitherto confounded with Lepiota 
holosericea and L, naucina, from which it is readily distinguished by 
the rosy colour of the gills, this colour appearing deepest the day 
after collection. The figure in Cooke’s Illustrations, pl. 524, called 
Agaricus (Psalliota) cretaceus, Fr., belongs to the present species. 
Lepiota prominens Fries, Fr. Hym. Eur. 30 (= Agaricus porrigens, 
Viviani, Fung. Ital. pl. 12). Pileus globose then expanded, umbo 
large and subacute, disc covered with imbricated scales, the remainder
