DAEDALEA. 191 



On dead oak stumps, and trunks. Beaching to 6 in. or 

 more across ; pores 5 1 in. deep, dissepiments flexible. 



Pileus dimidiate, sessile, of a pale buff colour, and firm and 

 corky substance. The surface is marked with concentric 

 lines, which are sometimes changed into concentric ridges, 

 more or less rough, with little knobs and inequalities, but 

 always glabrous, and having a woody appearance to the eye. 

 Hymenium composed of large, deep, sinuous, irregularly 

 anastomosing lamellae, of a paler colour than the pileus, 

 entire and rounded at the edges. The form of the pileus is 

 very inconstant. In general it is more or less semicircular, 

 nearly horizontal, subentire, and the hymenium forming 

 either a boldly convex or nearly straight line from the margin 

 to the base, where the lamellae are often two inches in length. 

 Sometimes numerous smaller pilei are attached inseparably 

 together in various directions, and press one another out of 

 shape. In like manner the hymenium also varies, and some- 

 times permits the lamellae "to fall down like the folds of a 

 curtain. The flesh is of a pale reddish-brown, darker than 

 the lamellae ; and though of considerable substance in some 

 specimens, in others is scarcely thicker than one eighth of an 

 inch. (Grev.) 



Perennial. Pileus 5-6 in. broad, sessile, dimidiate, of a 

 pale woody appearance, smooth, marked with concentric 

 raised or depressed zones and little radiating wrinkles, the 

 margin in well-grown specimens is thin, but in ill-developed 

 individuals swollen and blunt, in which state it is D. gibbosa, 

 Purt. Gills of the same colour as the pileus, with sometimes 

 a slight shade of pink, woody, thick, sinuous, branched and 

 anastomosing, so as to form long wavy pores a line or more 

 broad. Sometimes the whole plant is resupinate or decurrent, 

 in which case the partitions are often elongated into tooth- 

 like processes. (Berk.) 



Daedalea aurea. Fr. 



Pileus 1-2 in. across, rather thin, coarsely velvety, golden 

 or tawny, more or less zoned ; pores narrow, very sinuate, 

 with the flesh pale yellow.

 Fung., p. 224. 



On oak, &c. Pileus more or less triangular.
