HYMENOMYCETES. 



151 L. RUFUS. Scop. 9^. 3 — 4. i. 



Pileus depressed, at length iiifundibuliform, often with a small 

 umbo; deep brick red, milk acrid. Fir woods. Stourton. 

 Bidston. Eainford. 



15Q L. GLYCiosMus. Fries. 1^. 2i. |. 



Pileus pale, lurid ; gills yellowish. Known by its strong 

 scent, like that of oranges. Hangsdale's Wood. October, 1856. 



Genus IX. RUSSULA. 



153 R. NIGRICANS. Fries. Ep. 2—3. 3—6. |— 1^. 



Pileus jiale yellowish brown, with dirty olive stains ; gills 

 rounded behind, brittle, very thick and distant. The whole 

 plant becomes coal black without losing its shape or firmness. 

 A. adustus, E.F. Woods. Eastham. Woolton. Hangsdale. 

 Knowsley. 



154 R. YESCA. Fries. 9—3. 3^5. i— 1. 



Pileus convex, at length expanded, centre depressed, smooth 

 and somewhat viscid when young, in age slightly rugulose, 

 with a sub-striated margin ; gills rather broad and distant, 

 occasionally forked, white ; stem firm, rivulose, white or 

 tinged with the colour of the pileus which is extremely vari- 

 able, purplish bright or pale red, livid, yellowish or white. 

 A. emetictis, E.F. in part. The difficulty is great of assigning 

 this, the most common of all the Eussulas, to any species 

 named in the Ejjicrisis. li. vesca is, however, A. integer, of 

 Bolton, plate 1 ; which is also A. emeticus, E.F. 



155 R. viREscEKS. E.F. 2. 4. i—i 



Pileus rugulose, centre depressed, greenish with olive purple 

 or yellow shades ; gills forked, white ; stem firm, white. 

 Following the synonyms I have, in the List of British Hyme- 

 nomycetes, assigned this species to H. heter&pliylla, the descrip- 

 tion of which in the Epicrisis does not accord with that of 

 A. virescons in the E.F. The present species may easily be 

 known by the rugulose surface of the pileus, over which there 

 is an extremely thin glazed pellicle. In woods not lancommon. 



156 R. RUBRA. Fries Ep. 2. 3—5. i. 



Pileus depressed, smooth, bright rose colour ; gills forked, 

 white ; stem unequal, pjiler than the pileus. Whole plant 

 very firm. Under trees, Halsnead Park. 



157 R. FCETENS. Pers. 3 — 4. 4 — 6, 1. 



Pileus much depressed, colour of pie-crust, Init dirty looking, 

 margin furrowed and tuberculatcd. An untidy looking plant, 

 appearing under trees and on lie<lge banks early in autinnn, 

 and lasting but a short time.
