132 FUNGUS-FLOKA. 



Stereum ocfiroleucum, Fries, Hym. Eur., p. 639 ; Mass., Mon. 

 Thel., p. 184. 



Corticium ochroleucum, Fries, Epicr., p. 577. 



On wood and bark. Silky or strigose, becoming smooth 

 when old. It is not unusual to meet with all stages from 

 flabelliform to entirely resupinate. Distinguished from S. 

 strigosum by the very pale ochraceous hymenium that becomes 

 much cracked when dry ; the spores are also different. 



Stereum purpureum. Pers. (fig. 14, p. 97.) 

 Coriaceous but pliant, effuso-reflexed, more or less imbri- 

 cated, tomentose, zoned, whitish or pallid ; hymenium naked, 

 smooth, even, pale clear purple, becoming dingy ochraceous 

 with only a tinge of purple when dry; spores elliptical, 

 7-8 x 4 p.. 



Stereum 'purpureum, Persoon, Obs. Myc. ii. p. 92; Mass., 

 Mon. Thel., p. 186. 



On trunks, branches, &c. Variable ; often broadly adnate, 

 with the extreme margin only free and reflexed, or broadly 

 reflexed and imbricate, when the individuals are often small, 

 not more than ^-1 in. across, but sometimes much larger, 

 rather thin, rigid and incurved when dry. Pileus silky, 

 tomentose, not coarsely strigose as in S. hirsutum, and often 

 with one or two narrow black zones near the margin ; hyme- 

 nium more or less purple, becoming dingy ochre when dry. 



Stereum sanguinolentum. Fr. 



Effuso-reflexed, thin, coriaceous, pileus silky-adpressed, 

 substriate, pallid, margin acute, whitish ; hymenium even, 

 glabrous, very delicately pruinose when old, becoming 

 stained with dingy red when rubbed ; spores cylindrico- 

 ellipsoid, slightly curved, 8-9 X 4-5 p. 



Stereum sanguinolentum, Fries, Epicr., p. 549 ; Mass., Mon. 

 Thel., p. 189. 



On pine and other wood. Densely gregarious; at first 

 resupinate and circular, at length dimidiate or with the 

 margin more or less reflexed all round, silky or almost 

 strigose, zoned, the zones darker ; hymenium rough from the 

 inequalities of the matrix, otherwise smooth, pale greyish- 

 brown, when scratched or bniised becoming instantly blood- 

 red. (Berk.)
