here given are taken from American specimens. Some authorities 

 say spores " sphaeroid, 2-3 /x in diameter." 



Clitocybe peltigerina Pk. 



PELTIGERINE CLITOCYBE 

 N. Y. State Mus. Rep't 30, p.38 



Pileus thin, nearly plane, umbilicate, glabrous, hygrophanous, 

 brown and striatulate on the margin when moist, whitish or pale 

 gray when dry ; lamellae subdistant, sometimes branched, decurrent, 

 brownish, interspaces venose ; stem nearly equal, solid, glabrous, 

 rather firm, paler than the pileus, often with a minute white 

 tomentum at the base ; spores ellipsoid, 8 x 5 ;«,. 



Pileus 4-10 mm broad; stem 12-20 mm long, 1-1.5 mm thick. 



Among species of lichens (Peltigera). Albany and Oneida 

 counties. May. Rare. 



Sometimes two or three stems are united at the base, thus mani- 

 festing a tendency to become cespitose. 



Clitocybe metachroa Fr. 



CHANGEABLE CLITOCYBE 

 Sylloge V, p.iSs 



Pileus thin, convex becoming plane or centrally depressed, 

 glabrous, hygrophanous, brownish or grayish brown when young 

 and moist, whitish when dry, margin slightly striate when old ; 

 lamellae thin, narrow, close, linear, adnate or slightly decurrent, 

 whitish or cinerous; stem equal, tough, externally fibrous, stuffed 

 or hollow, terete or compressed, whitish, mealy or pruinose at the 

 top, colored like the pileus ; spores 6-8 x 3-4 /x. 



Pileus 2.5-4 cm broad ; stem 3-4 cm long, 4-8 mm thick. 



Pine woods. Albany co. November. Rare. Found but once. 



The marked change of color between the moist pileus and the dry 

 one is suggestive of the specific name. The mealy or pruinose top 

 of the stem, its habitat in pine woods and its late appearance are 

 guides in the identification of the species. 



Clitocybe vilescens Pk.
