Report of the State Botanist 133 



Polyporus annosus Fr. 



Decaying wood. Salamanca. September. 

 This is evidently a very rare species in our State. 



Daedalea sulphurella n. sp. 



Eesupinate, effused or nodulose, pale sul^Dhur yellow; pores 

 short, labyrinthiform, the dissepiments often lacerated and irpici- 

 form in the dry plant ; pores subglobose or broadly elliptical, .0002 

 in. long-. 



Much decayed wood. Salamanca. September. 



Mostly very irregular or nodulose, following the irregularities of 

 the wood and encrusting mosses. It is of a beautiful pale yellow 

 color when fresh, but it changes to a dull pallid hue when dry. 



Daedalea extensa n. sp. 



B-esupinate, thick, coriaceous, often uneven or somewhat nodulose, 

 the margin at first cottony and white, soon changing to brown, the 

 subiculum slightly rufescent ; pores large, unequal and labyrinthi- 

 form, in vertical places oblique, whitish; spores minute, oblong, 

 .00024 to .0003 in. long, .0001 to .00012 broad. 



Prostrate trunks of deciduous trees. Salamanca. September. 



This forms patches two feet or more in length on the sides and 

 lower surface of the trunk. It follows the inequalities of the sur- 

 face, and in vertical places it becomes more or less nodulose or 

 develops a ■ thick obtuse margin, which is velvety-tomentose and at 

 length dark-brown in color, but I have seen no reflexed margin. It is 

 suggestive tof resupinate forms of Trametes mollis, but differs from 

 it in the character of the pores in the thicker subiculum and in the 

 absence of any free margin. 



Hydnum caput-ursi Fr. 



Decaying birch wood, Betula lutea. Carrollton. September. 



Hydnum arachnoideum n. sp. 



Resupinate; subiculum effused, very thin, webby or cottony, 

 white ; aculei minute, short, conical, unequal, scattered or sometimes 

 crowded, whitish ; mycelium often forming slender branching white 

 radicular strings that creep over or permeate the matrix ; spores 

 minute, globose, .00016 in. broad. 



Much decayed wood of hemlock, Tsuga Canadensis. Salamanca. 

 September.
