4174. On a corticated oak branch, February 23, 1920. Color of damp hymenium 

 about gold; grayish flesh when dry. 

 Also man}- other collections on oak, sumac, ironwood, privet and peach.

7a. Stereum rameale. Form on cedar. 



We have in Chapel Hill a form on Juniperous poles which differs 

 from the typical in the much grayer and more tomentose surface 

 in the smoky hymenium, and in never reaching the larger sizes often 

 found in the latter. These differences remain constant from year to 

 year, but as the spores and other microscopic , characters are the 

 same, I agree with Dr. Burt, who has seen my plants, that it is best 

 to refer them to S. rameale. A description follows: 



Shape and size as in smaller examples of the typical form, mostly 

 petal-shaped and attached by a constricted base, projecting about 

 4-8 mm., at times largely resupinate, often in rows; dorsal surface 

 light brown when damp with narrow zones of blackish brown, the 

 margin white or black; scurfy tomentose nearly all over (a few nar- 

 row glabrous zones are present at times); radially channelled; when 

 dry pale gray with narrow blackish zones and an obscure cinnamon 

 tint towards the margin. Hymenium uneven, smoky brown to 

 smoky buff when damp, when dry smoky gray, the marginal part 

 darker. 



Spores exactly like those of *S. rameale, smoky flesh color, 1.8- 

 2.8 X 5-6.6[x. 



Stereum radiatum Pk. which also grows on conifers (hemlock and 

 spruce) in the northern states is very different.

8. Stereum sericeum (Schw.) Sacc. 



Plate 35 



Plant arising from a little tubercle and, if beneath a branch, 

 largely resupinate by fusions, reaching a length of 6 or 7 cm., the 

 free and shelving margins not continuous but discrete and forming 

 separate petal-like brackets which vary from very small up to 2 cm. 

 broad and extending 1.5 cm.; often not resupinate and attached 

 directly to the wood by a point. Dorsal surface smooth, silky-
