row zones of the surface. Stcreum coniplicatuiii, Fr. Seems to me a 

 name applied to crisped and folded forms of both this and the pre- 

 ceding species. 



7. S. ocHRACEOFLAVuisr, Schw. Coriaceous-membranaceous, 

 thin. Pileus effused and reflexed, strigose-hispid, white or pale 

 yellow. Hymenium even, glabrous, pale yellow. 



Attached to the underside of the smaller branches. Pileus re- 

 flexed scarcely more than \ of an inch, effused and more or less 

 confluent, scarcely zonate, often attached by the back and hanging 

 free all around like a litde cup or shield. Remarkable for the long 

 hairs that invest the pileus. Specimens I have from the East are 

 white as Schweinitz states, but those I have found in this region are 

 pale yellow or ochraceous. 



8. S. SERicEUM, Schw. Coriaceous-membranaceous, thin. 

 Pileus effused and reflexed, silky-striate, subzonate, shining, pale 

 alutaceous. Hymenium even, pallid. 



Attached to the lower side of bran chiefs and twigs ; not com- 

 mon. Pileus nearly half an inch in length and breadth, but com- 

 monly extensively effused and more or less confluent below or 

 sometimes attached by a point and free all around. The surface 

 presents a silky luster with faint zones ; the striate appearance is 

 caused by innate radiating fibrils. It is very distinct from 6". radiaris. 

 It is Thelephora striata, Fr. of the Elenchus, but \xq\. Stereuni striatum, 

 Fr. of the Hym. Eur. 



9. S. BicoLOR, Pers. Submembranaceous, soft. Pileus 

 conchate-reflexed, azonate, villous becoming glabrous, dark brown. 

 Hymenium thin, glabrous, white. 



On old stumps and trunks ; not rare. Pileus 1-2 inches in 

 length and breadth, subimbricale, confluent at the base. Readily 

 distinguished by the brown upper surface and the white 

 hymenium. 



10. S. ALBOBADiUM, Schw. At first rcsupiuate, bright brown 

 with a wliite border; soon confluent and effused with a narrow sub- 

 membranaceous margin; the margin undulate or subpileate, thin, 

 subzonate, brown. Hymenium bay brown, somewhat velvety. 



On the lower side of branches; very common. It begins its 

 growth with a number of orbicular brown spots having a white 

 border, these enlarge and become confluent forming one resupinale 

 specimen effused for several inches; then occasionally a narrow 

 subpileate margin is turned back on one or both sides, this margin 

 is very narrow scarcely ever reaching \ of an inch in breadth. The
