Mucronoporus fulvidus E. & E. 



Ou dead limbs of Alnus, Berkeley, Gala., Jan., 1894 (W. C. 

 Blasdale, No. 181). 



Resupinate, adnate, tawny-yellow, extending along the limb for 

 6-8 or more centimeters and 3-4 cm, wide, margin velvety tomen- 

 tose, narrow, sterile, adnate. Pores short (1 mm. or less), round, 

 extending down to the matrix without any distinct subiculum. 

 Spores hyaline, sub-globose, about 2// diam. Spines tolerably 

 abundant, 25-35 x 3-4//, rather pale. 



Has the aspect of Poria inermis E. & E., but surface of pores 

 more uneven, and spiny within. 



Hydnum Washingtonianuin E. & E. 



On the ground in deep coniferous woods, Tracyton, Kitsap Co., 

 Wash., Dec, 1893 (Adella M. Parker, No. 214). 



About 4 cm. high, pale orange, carnose, subviscose. Stipe cen- 

 tral, 3 mm. thick, subatteuuated below. Pileus about 4 cm. across, 

 slightly depressed in the center, thin, glabrous, wrinkled when dry. 

 Aculei subulate, cylindrical, 3-5 mm. long, pale yellow, nearly white 

 when fresh, decurrent half way down the stem. Spores angular- 

 globose, (white)?, 6-7,a diam., borne on clavate-cylindrical basidia 

 20-22 X 6;/, with 4 erect, slender sporophores about 6;/ long. 



From H. repandum, to which it is closely allied, it differs in its 

 decurrent aculei and tougher substance. 



Tremellodon piisillum E. & E. 



On rotten wood, among coniferous trees, Tracyton, Wash., Dec, 

 1893 (Adella M. Parker, No. 212). 



Small, stipitate, gelatinous, white and nearly transparent. Pileus 

 subreniform, membranaceous, 1-1 2 cm. across, smoky-brown above 

 and sparingly clothed with weak, pale hairs. Teeth not crowded, 

 white, subcompressed, about 2 mm. long, narrowed gradually from 

 the base, with a few obtuse, short, lateral, tuberculiform branches or 

 processes. Spores ovate-globose, 5-6 x 35-4//, consisting of a thin, 

 transparent sack containing a single, large globose nucleus. Stipe 

 lateral, cylindrical, slender, equal, hirto-pubescent, 1 cm. long, 2 

 mm. thick, smoky-brown. 



T. hirneoloides B. & C. is a much coarser, stouter plant, with 

 stipe 18 mm. long, 8 mm. thick at the base.
