Peck : New Sjpecies of Fungi 



k w 



Gregarious or cespitose ; thin woods, Mt Gretna, Pa. 'Au- 

 gust. Mcllvaine. 



A large fine species distinguished from its near allies by the ab- 

 sence of pink hues from the gills. Mr. Mcllvaine remarks that 

 it has an anise-like flavor and odor and that when young the whole 

 fungus is tender and high-flavored but when full grown only the 

 caps are edible. 



I 



Agaricus argenteus Braendle /// ////. 



r 



Pileus thin, convex becoming nearly plane, slightly silky or 



brown, shining with 



:l 



glabrous, pale grayish white or grayish 

 silvery luster when dry, the margin sometimes striate, at first in- 

 curved, often revolute when old, flesh whitish, becoming blackish 

 where cut ; lamellae close, free, at first brownish, becoming black- 

 ish brown or black with age ; stem short, glabrous, solid, often 

 narrowed toward the base, the annulus slight, evanescent ; spores 

 broadly elHptic, 7-10 /J. long, 6 n broad. 



Pileus 2.5-5 ^^^^' broad ; stem 2.5-4 cm. long, 4-8 mm. thick. 



Lawns and grassy places in rich soil. Often associated with 



yp/i 



After rains from April to November. 



J 



This is a small mushroom, peculiar in having the young lamellae' 

 of a dark color and in the absence of any pink hues. The lamellae 



■ 



sometimes become moist and manifest a tendency to deliquesce. 

 The drying specimens emit a strong but not unpleasant odor. 

 Mr. Braendle says that their edible quality is excellent and that it 

 is not impaired by drying. 



Psathyra microsperma 



Pileus ovate or subhemispherical, becoming deeply convex or 



subcampanulate, obtuse, even, hygrophanous, brown when moist 

 paler when dry, slightly floccose when young, flesh brownish ; 

 lamellae thin, close, adnate, brown ; stem equal, hollow, fibrillose ; 

 spores brown, elliptic, 5-6 /x long, 3—4 /t broad. 



Pileus 1-2.5 cm. broad ; stem 2.5-3 cm. long, 2-3 mm. thick. 



Cespitose about old stumps, Ohio. April. Lloyd. 



The white floccose tufts of the 23ileus and the white fibrils of 

 the stem are easily destroyed in handling the specimens. The 

 species is similar in the ornamentation of the pileus to Psilocybe 

 senex Pk. 



Coprinus laceratus 



Pileus thin, at first ovate and covered with a white separable 

 floccose coat which soon separates into scales or patches and
