SORDID TRICHOLOMA 



PLATE 115 



Pileus thin, campanulate or convex becoming plane or centrally 

 depressed, subumbonate, glabrous, sometimes wavy or irregular on 

 the margin, hygrophanous, dark brown or subviolaceous when 

 moist, pallid or subalutaceous when dry, flesh white, taste sweetish, 

 then disagreeable; lamellae thin, subdistant, sinuate, adnate or 

 subdecurrent, violaceous when young, then whitish or smoky 

 brownish, sometimes ting-ed with pink; stem equal or slightly 

 thickened at the base, stuffed or occasionally hollow in large 

 specimens, colored like or a little paler than the pileus, sometimes 

 fibrillose striate; spores pinkish, .0003 of an inch long, .0002 

 broad. 



The sordid tricholoma in this part of our country is most often

 from specimens collected by H. W. Barratt in Poughkeepsie. 

 They were found growing in a greenhouse devoted to the culti- 

 vation of violets. Specimens of it were received a little later from 



B. C. Williams of Newark, Wayne co. These were collected in a 

 greenhouse devoted to the cultivation of carnations. The species 

 is related to the naked tricholoma, Tricholoma nudum 

 (Bull.) Fr. witli which it was for a time confused, but from 

 which it may be distinguished by its tougher hygrophanous cap. 

 In Europe it is said to grow on manure and in rich cultivated soil 

 in gardens. 



The cap is thin .except in the center where it sometimes has a 

 prominence called an umbo. It has a moist appearance and a
