CLASSIFICATION 205 



curved, not rooting, downy, white, ring white, soon torn, adhering 

 for some time to the edge of the cap. 



On trunks of beech, etc. 



** Veil and ring absent ; gills sinuate or adnate. 



P. ulmarius. — Cap fleshy, compact, horizontal, fairly regular, 

 but more or less excentric, convex, then plane and disciform, 

 even, smooth, livid, becoming pale but marbled with roundish 

 spots, 3-7 in. across ; gills emarginate and rounded behind, slightly 

 adnexed, broad, rather crowded, whitish ; stem solid, elastic, 

 somewhat excentric, curved, stout, downy, white, 2-3 in. long. 



Often very large. When the fungus grows from the side of a 

 trunk the stem is more or less excentric and ascending ; when 

 growing on a horizontal surface the stem is often central and erect, 

 when it resembles a Tricholoma, but distinguished by growing on 

 wood. 



P. decoriis.^CsLp fleshy, brittle, convex, then expanded or de- 

 pressed, often excentric, yellow, covered with darker fibrils, 2-4 in. 

 across ; flesh thin, pale yellow ; gills adnate or sinuato-adnate, 

 golden yellow, stem covered with fibrils that blacken with age. 



Readily known by the golden yellow gills. 



On rotten stumps, etc. 



P. tessulatus. — Cap horizontal, compact, thick, convex, then 

 plane, depressed behind in lateral forms, rather irregular, smooth, 

 palhd tawny, marked with paler roundish or polygonal spots, 3-4 in. 

 across ; gills sinuate, adnexed, thin, crowded, white, becoming 

 tinged yellow ; stem solid, very excentric, curved, smooth, white, 

 about I in. long. 



Allied to P. ulmarius, but more irregular in form, smaller, and 

 with a smell of new meal. 



On trunks. Solitary or tufted. 



P subpalmatus. — Cap thick, soft, convex, then more or less 

 flattened, irregularly circular, obtuse, wrinkled, with a gelatinous 

 cuticle, rufescent, 3-5 in. across ; gills adnate, broad, crowded, 

 joined behind, dingy ; stem excentric or almost lateral, but the 

 cap is always marginate behind, fibrillose, short, fleshy, fibrous. 



Very remarkable for having the flesh marbled is in Fistulina 

 hepatica. Cap, especially when young, covered with a viscid pellicle. 



On old trunks, squared timber, etc. 



P. craspedius. —Csip more or less excentric, sometimes almost 

 lateral, but always marginate behind, depressed behind when 

 very excentric, brick-red or tan-colour after rain, becoming pale, 

 also sometimes greyish, smooth, edge at first incurved, then ex- 

 panded and crenately lobed or fimbriate, 3-6 in. across ; gills 

 adnate, very thin, crowded, narrow, at length torn, white ; stem 

 sometimes very short, at others up to 3 in. long, firm, elastic, 

 pallid, usually smooth.
