AURICULAUINI. 271 



except S. rugosum and the following, wliich is confined to 

 Conifers, by its turning red when scratched or bruised. 



4. S. sanguinolentum, Fr. ; thin, coriaceous ; pileus effused 

 and reflexed, silky, somewhat striate, pallid; margin acute, 

 white; hyraenium even, smooth, cinereous-brown, bleeding 

 when wounded. — Grev. t. 225. 



On wood of Conifers. Very common. Colour far less bright 

 than that of the last. A. hepatica, Sow. t. 388. f. 2, is 

 merely a washed state of one of the foregoing species, pro- 

 bably S. purpuTeum. 



5. S. rugosum, Fr. ; corky, rigid ; pileus effused and shortly 

 reflexed, obtusely margined, at length smooth, bright brown ; 

 hymenium dull, pruinose, bloodstained when wounded. 



On stumps, especially hazel. Extremely common. Some- 

 times surviving one or more seasons, and then thick and zoned 

 within. T. Laurocerasi, Berk, in Eng. Fl., is, I believe, a 

 thin, resupiuatc form of this species. A. cinerea, Sow. t. 388, 

 f. 3, is, I think, merely Corticium quercinum. 



6. S. acerinum, Fr.; erustaceo-adnate, even, smooth, white. 

 On trunks of living maples. Very common. 



37. HYMENOCH^TE, Lev. 

 Coriaceous, dry. Hymenium even, beset with short, stiff, 

 coloured bristles. 



1. H. rubiginosa, Lev.; coriaceous, rigid; pileus effuso- 

 reflexed, somewhat fasciate, velvety, rust-coloured, then smooth, 

 bright brown; intermediate stratum tawny-ferruginous ; hyme- 

 nium ferruginous. — Sow. t. 26. 



On gate-posts, etc. Very common. 



2. H. tabacina, Lev.; coriaceous, then flaccid ; pileus effused, 

 reflexed, silky, at length smooth, subferrugiuous ; margin and 

 intermediate filamentous stratum golden-yellow ; hymenium 

 paler.
