Clitocybe biformis Pk. 



TWO-FORM CLITOCYBE 

 N. Y. State Mus. Bui. 150, p.25, pl.VI, fig.g-iS 



Pileits fleshy but thin, broadly convex or nearly plane becoming 

 centrally depressed or subumbilicate, glabrous, even or obscurely 

 striate on the involute margin, pale buff, more deeply colored in 

 the center, flesh white ; lamellae thin, close, narrow, decurrent. 

 whitish or pallid becoming subcinnamon with age or in drying; stem 

 equal, firm, solid or stuffed, often curved, sometimes eccentric, 

 tomentose at the base, colored like or a little darker than the pileus ; 

 spores broadly ellipsoid or subglobose, 5-6 x 4-5 [x. 



Pileus 2.5-7.5 cm broad; stem 2.5-3.5 cm long, 4-8 mm thick. 



Growing in circles or arcs of circles in woods. Essex co. Sep- 

 tember. Found but once. 



This species is remarkable for the change in form in passing from 

 youth to old age, and also for the change in color of the lamellae. 

 The pileus sometimes has a moist sodden appearance as if water- 

 soaked. The mycelioid tomentum at the base of the stem causes a 

 mass of decaying vegetable matter to adhere closely to the stem 

 when pulled from its place of growth. 



Clitocybe odora (Bull.) Sow.
