372 FUNGUS-FLORA. 



Caespitose. Smell strong ; tlie stem is sometimes almost 

 central. Distinguished from all species except P. corticatus 

 by the gills anastomosing behind, and often forming an open 

 network on the stem-like base. Known from P. corticatus by 

 absence of a ring on the stem. Edible. 



Imbricated, large. Pileus subdimidiate, very thick and 

 fleshy ; flesh white, dusky towards the surface, 1 in. deep) ; 

 the border at first fibrillose or even decidedly squamulose, 

 mai'gin involute ; as the pileus expands the white fibrillae 

 vanish and the colour changes from dusky to bistre ; margin 

 paler and rimulose, the \vhole surface shining and satiny 

 when dry, soft and clammy when moist; towards the base in 

 age there is a little white down. Gills broad, here and there 

 forked, anastomosing at the base, dirty- white, the edge ser- 

 rated, umber. In large specimens there is often a distinct 

 stem, clothed with a dense short white down, which runs up 

 between the gills. When dr^", the pileus becomes pallid or 

 3'ellowish. Taste and odour like that of A. personatus^ which 

 it resembles somewhat in colour. Stem strjgose at the base, 

 according to Fries. (Berk.) 



Var. glandulosus. With the habit of the typical form, 

 but larger; pileus dark brown, becoming pale; gills white, 

 with scattered small wart-like or glandular bodies. 



Agariciis glandulosus, Bulliard, t. 426. 



On trunks. 



A very constant, but somewhat rare variety; easily known 

 by ihe dark brown pileus. The gland-like bodies on the 

 gills are due to the outward giowth of the hyphae of the 

 trama in minute patches here and there. 



Var. euosmus, Cke., Hdbk.,''p. 105 ; Cke., Illustr., pi. 196. 

 . Agaricus (Pleurotus) euosmus, Berk., Outl., p. 185. 



Strong scented, imbricate ; pileus fleshy, depressed, shining, 

 silky when dry, at fiist white with a tinge of blue, then 

 brownish ; stem short or obsolete ; gills decurrent, ventri- 

 cose, dingy white, spores 12-14 X 5 /t, pale pinkish-lilac. 



On elm trunks. 



Pilei very much crowded, 2 in. or more across, deeply de- 

 pressed, unequal, at first white, invested with a slight blue 

 varnish, at length of a pale brown ; stems distinct above, 

 connate below; gills rather broad; running down 'to the
