NATURAL HISTORY SURVEY G9 



Gregarious, oespitose ; taste very astringent. Pileua L.5 to 

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

 obovoid-sphaeroid, 2 to 3x1 to 2 /a. 



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. 



Pilous pallid, margin concolorous L. betulina. 



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

 gin yellowish L. sepiaria. 



Pilous dull-brown or grayish-brown, margin 



cinereous L. vial is. 



Lenzites betulina Fr. 



Pilous 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 /*., often curved. 



Lenzites sepiaria Fr. 



Pileus tawny-yellow when young (remaining so on the mat gin 

 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 inl^r 

 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 fiat, 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.
