(Plate CLXXXIX.) 



the cap is sometimes shaggy, especially in young plants, by the adher- 

 ing fragments of the whitish veil. 



The gills are thin, closely placed side by side and rounded at the 

 end next the stem, but they are not attached to the stem. They are 

 white. The stem is rather long and slender, fragile and adorned with 

 loose, soft fibrils or flocculent, cottony tufts, which give it a somewhat 

 shaggy appearance, but it becomes smoother as the plant grows older. 



The cap is usually from 12.5 inches broad, and the stem from 1.53 

 inches long and 1.53 l mes thick. The plants grow in woods, specially in 

 hilly and mountainous regions, and are generally solitary or few in a place, 

 but in favorable seasons they are of frequent occurrence and may be found 

 from July to October. Though small and thin, the caps are well-flavored 

 and make a desirable dish. L. metulaespora B. and Br. scarcely differs 

 from this species, except in the striate margin of its cap. Peck. 



Tricholoma subacutum Pk. Rep., 1888: 112. Pileus at first ovate 

 or broadly conical, then convex and subacutely umbonate, dry, silky 

 and obscurely virgate with minute innate fibrils, whitish tinged with 



smoky-brown or bluish-gray, darker 

 on the umbo. Flesh white, taste acrid 

 or peppery. Lamellae rather close, 

 slightly adnexed, white. Stem equal, 

 stuffed or hollow, silky -fibrillose, 

 white. Spores broadly elliptical or 

 subglobose, .00025 to .0003 inch long, 

 .0002 to .00025 broad. 



Pileus 1.5 to 3 inches broad; stem 

 2 to 4 inches long, 3-6 lines thick. 



Woods and groves. North Elba, 

 Essex county, New York. Septem- 

 ber. 



The species is perhaps too closely 

 related to T. virgatum, but it is sep- 

 arable by its prominent subacute 

 umbo, paler pileus, hollow stem and 

 hot or peppery taste. The cuticule 

 is separable from the pileus. Peck. 



In his Report for 1902, page 39, Prof. Peck redescribes the species
