 Pk is like the common form except that the gills are pallid. This 

 species and its varieties are sometimes confused with LacUmm 

 subdulcis. 



795. Clitocybe tortilis Fr. 



(Laccaria tortilis) 



Hymen. Europ., 1874. 



Illustration: Patouillard, Tab. Analyt., No. 105. 



PILEUS 5-12 mm. broad, submembranaceous, convex then ex- 

 panded and depressed on disk, distantly radiately striatulate from 

 the center when moist, hygrophanous, pale reddish or salmon color, 

 pruinose, disk whitish-scurfy, margin sometimes plicate or split- 

 ting, often deformed or irregular. GILLS distant, rather narrow, 

 adnate-subdecurrent, thick, not forked nor veined, salmon-colored, 

 edge concolor. STEM 1-2 cm. long, 1 mm. thick, slender, equal, 

 fibrous-tough ish, stuffed with a white pith, pellucid flesh color, gla- 

 brous, base white-mycelioid. SPORES large, globose, long-echmu- 

 late, white, 12-14 micr. diam. ; basidia 2-spored. 



On the ground, in wet places, sometimes on moss. Marquette. 

 August-September. 



This is a distinct species and must not be confounded with C. 

 laccata nor its varieties. The spores are nearly twice as large as 

 in that species. It is easily mistaken for a species of the rosy- 

 spored genus Eccila. It has sometimes been referred to as a 

 variety of C. laccata.
