NATURAL HISTORY SURVEY 69 



Gregarious, cespitose ; taste very astringent. Pileus 1.5 to 

 2.5 cm. broad; stem not reaching 2.5 cm. in length. Spores 

 obovoid-sphaeroid, 2 to 3 x 1 to 2 //.. 



On stumps. Autumn. Common. 



LENZITES. 



Tubes near the point of attachment, elongate, radiating, 



formed by the anastomosing of lamellae which are free at the 



margin. 



Sessile, or accidentally resupinate. 



Pileus pallid, margin concolorous L. betulina. 



Pileus tawny-yellow, becoming date-brown, mar- 

 gin yellowish . .L. sepiaria. 



Pileus dull-brown or grayish-brown, margin 



cinereous L. vialis. 



Lenzites betulina Fr. 



\ 



Pileus dimidiate, sessile, persistent, corky-coriaceous, obos- 

 letely zonate, tomentose, pallid. 



Lamellae straight, somewhat branched, anastomosing, sordid 

 white. 



On stumps, frequent. July to autumn, persisting through the 

 winter. Pileus 5 to 7.5 cm. broad, projecting 2.5 to 5 cm., often 

 imbricated and laterally concrescent; spores white, oblong, 6 to 

 8 x 3 p., often curved. 



Lenzites sepiaria Fr. 



Pileus tawny-yellow when young (remaining so on the margin 

 when full grown), becoming date-brown when full grown and 

 black when old, corky-coriaceous, hard, convex becoming plane, 

 sometimes orbicular, more frequently extended longitudinally, 

 zoned, strigose-tomentose, at length squamulose and pitted; 

 flesh tawny. 



Lamellae extended to the base, very rigid and firm, branched, 

 more or less anastomosing, yellowish becoming umber, the edge 

 entire or slightly toothed. 



On pine stumps and prostrate trunks, Millers. On the stump 

 of a pine street tree, Wheaton. At the first the border of the pileus 

 is whitish and somewhat floccose-tomentose, but soon changes to 

 orange-tawny. When growing on the sides of a stump the plants 

 are dimidiate and imbricated; those growing on the flat, squared 

 surface of a stump remain more or less orbicular, forming resup- 

 inate areas with a narrow gill-bearing border. 



Lenzites vialis Pk. (Plate VIII, Fig. 1.) 



Pileus coriaceous, sessile, dimidiate or elongated, sometimes 

 confluent, obscurely zoned, subtomentose, brown or grayish- 

 brown, the margin cinereous. 



Lamellae thin, abundantly anastomosing, pallid, cinereous- 

 pruinose on the edge when fresh. Pileus 12 to 24 mm. broad.
