CLASSIFICATION 423 



** Free portion horizontal, attached by a broad base. 



S. hirsutiim (PI. XXXII, fig. 8). — Pileus horizontal or partly 

 attached to the matrix and partly free, or almost entirely adnate 

 and hymenium upwards. Pileus coarsely fibrous, dingy ochraceous ; 

 hymenium bright ochraceous tan, sometimes almost orange. 



Very common on dead wood, posts, etc. The edge of the pileus 

 is often very much fluted or puckered. 



5. purpureum (PI. XXXII, fig. 4). — General habit, size, and 

 appearance of 5. hirsntum, but the hymenium and edge of pileus 

 pale clear purple when fresh, becoming dingy when old. The 

 pileus has often a narrow dark zone near the margin when young. 



On dead wood, also on living trunks and branches. 



S. spadicenm. — Thin and tough, attached with more or less of the 

 edge free ; hymenium brownish flesh-colour, becoming red when 

 bruised. 



Distinguished amongst the three species turning red when the 

 hymenium is bruised or scratched, by the thin substance, and dark- 

 coloured hymenium. 



5. sanguinolentum. — Usually forming crowded, more or less 

 circular, adnate patches, with more or less of a free margin, up to 

 1-2 in. across, thin ; pileus silky, pallid ; hymenium pale greyish 

 brown, becoming instantly blood-red when scratched or bruised. 



On wood and trunks, especially pine. The red stain when the 

 hymenium is injured is much more intense and quicker in appear- 

 ing than in either of the other species showing this character, 



5. rugosum (PL XXXIII, fig. 2). — Adnate, edge sometimes partly 

 free, rather thick and rigid ; pileus soon smooth, brownish ; hy- 

 menium pale yellow or greyish yellow, slowly becoming dull red 

 when scratched or bruised. 



Differs from P. sanguinolentum and P. spadicenm in the thicker, 

 more rigid substance. 



On dead wood ; also on living branches, especially those of 

 cherry laurel, where it acts as a destructive parasite. 



S. ochroleucum. — Spreading horizontally and fixed by a broad or 

 narrow base ; there is often a broadly adnate portion, or the whole 

 fungus may be adnate, leathery, rather thick, limp, silky, zoned, 

 greyish white ; hymenium pale ochraceous, smooth, cracked, 

 especially when dry. 



All stages are met with, from fan-shaped to entirely resupinate. 

 Pileus silky or strigose, becoming smooth when old. 



On wood and bark. 



S. disciforme. — Somewhat leathery, white, adnate, determinate, 

 the thin edge free, naked, discoid ; hymenium rigid, uneven, pul- 

 verulent, pallid. 



Forming subrotund patches -|-i in. across, very firm and rigid. 



On oak wood and bark.
