216 Peck : New species of fungi 



Lentinus microspermus 



Pileus fleshy, thin, convex, somewhat irregular, sometimes lobed 

 on the margin, glabrous, reddish-brown, flesh white, taste sweet, 

 then bitter ; lamellae thin, close, emarginate, adnexed, white., be- 

 coming creamy-yellow, the edge eroded or denticulate ; stems ces- 

 pitose, equal, glabrous, fleshy-fibrous, hollow, white or whitish, 

 sometimes eccentric ; spores minute, globose, white or faintly 

 tinged with yellow, 3-4 fi broad. 



Pileus 2.5-5 cm. broad ; stem 5-6 cm. long, 6-10 mm. thick. 



Decayed wood. Creve Coeur, Missouri. May. N. M. Glat- 



felter. 



Annularia sphaerospora 



Pileus fleshy but thin, conic or subcampanulate, becoming ex- 

 panded, umbonate, silky-fibrillose, yellow, fading to whitish either 

 wholly or in part, umbo brownish ; lamellae thin, close, free, 

 whitish or cream-colored when young, flesh-colored when mature ; 

 stem equal or slightly tapering upward, solid, fibrous, substriate, 

 whitish, annulate, the white collar sometimes near the middle, 

 sometimes near the base of the stem ; spores globose or sub- 

 globose, 5—6 fi in diameter. 



Pileus 3-6 cm. broad ; stem 3-8 cm. long, 4-8 mm. thick. 



Decaying wood of elm. Near Detroit, Michigan. August. 

 O. E. Fischer. 



The plants are sometimes cespitose. The species may be dis- 

 tinguished from its near relative, A. Fenzlii Schulz, by its umbonate 

 fading pileus and its whitish solid stem. A. Fenzlii grows on 

 Tilia. Twelve species of this genus are described in Sylloge, 

 none of which is credited to this country. 



amans 



Pileus convex, umbonate, subglabrous, yellowish-brown be- 

 coming brownish-red with age, or in drying, the umbo often 

 darker, the cuticle cracking, forming scales and disappearing 

 except on the umbo, flesh thin, white ; lamellae pallid becoming 

 ferruginous-brown ; stem firm, solid, fibrous, striate, subbulbous, 

 whitish and mealy above, reddish or brownish and slightly fibrillous 

 below, becoming wholly brownish with age ; spores irregular, 

 nodulose, 8-10 ft long, 5-6// broad. 



Pileus 2.5-4 cm, broad ; stem 5-7.5 cm. long, 2-4 mm. thick. 

 Woods. Near St. Louis, Missouri. July. N. M. Glatfelter.
