front, narrowed behind, white, rather distant, about 2.5 mm wide, 

 alternately long and short or nearly so. 



Stipe 5-15 cm long, 4-6 mm broad, concolorous, surface viscid, 

 felted, minutely scurfy-squamulose, crooked, terete or somewhat 

 grooved or flattened, base pointed and yellowish or equal and whitish 

 or grayish brown, stuffed. 



Spores 8-12 X 4.5-6 /a, ellipsoid to subellipsoid, smooth, yellowish 

 in Melzer's reagent. Basidia 42-74 X 7-11 /a, 2- and 4-spored. Pleuro- 

 cystidia 46-78 X 4-9 jx, subcylindric to more or less clavate, often 

 irregular, appendiculate; cheilocystidia 40-62 X 3-7 /a, subcylindric, 

 ventricose, tapering or appendiculate. Gill trama divergent, hyphae 

 4—8 fx broad. Cuticle an ixotrichodermium, the hyphae fuscous, at times 

 branched. Hypodermium present, similar to that of H. fuligineus. 

 Clamp connections present. Pileus trama loosely interwoven. 



Habit, Habitat, and Distbibution — Gregarious on soil, in pine 

 woods, District of Columbia and North Carolina. 



Matebial Studied — distbict of Columbia: Peck (type, collected 

 by Mrs. E. M. Williams, Nov. 20, 1897). nobth cabolina: Coker 

 10698, 10700. 



Obsebvations — Our notes on the type are recorded as follows: 

 Spores 8-12 X 4.-5-6.5 /a, ellipsoid or subellipsoid, smooth, yellowish in 

 Melzer's reagent. Basidia 42-74 X 7-11 fx, 2- and 4-spored. Pleurocys- 

 tidia 46-58 X 4-6 /a, subcylindric, slightly constricted, not projecting; 

 cheilocystidia 42-57 X 4-6 fx, similar. Gill trama divergent, hyphae 

 5-7.5 \x broad. Cuticle of fuscous, septate, branched, gelatinous hyphae 

 forming a turf, or ixotrichodermial palisade, with free hyphal ends 

 extending beyond the general level of the epicutis. Hypodermium pres- 

 ent, similar to that of H. fuligineus. Pileus trama loosely interwoven. 

 Clamp connections present on the cuticular hyphae. 



Coker's two collections resemble the type closely in all respects. 

 Murrill (1916) placed it in synonomy with H. hypothejus, but in this 

 latter species the colors are different and the spores are smaller than in 

 H. amygdalinus. Moreover, the odor in H. hypothejus is not distinc- 

 tive.
