SOME COMMON MUSHROOMS AND HOW TO KNOW THEM 23 



Tricholoma personatum is to be found quite commonly in the late summer 

 and fall months growing on the ground in woods and open places. This is one 

 of the most acceptable edible species. 



Tricholoma personatum and T. nudum are often confusing to the amateur, 

 but may be distinguished from each other by the fact that in T. nudum the 

 margin of the cap is naked and is thinner than in T. personatum. Also 

 T. nudumi is more slender than T. personatum and has deeper coloration on 

 the cap and gills. 



TRICHOLOMA RUSSULA. RED TRICHOLOMA. (EDIBLE) 



In Tricholoma russula, the cap is convex, later plane, and sometimes de- 

 pressed ; disk granular, viscid in damp weather, red or flesh-colored, becoming 

 lighter at the margin, which is involute and in young plants downy ; the flesh 

 is white or ringed with red under the cuticle, friable, taste mild ; the gills are 

 rounded or somewhat decurrent, rather distant, white, later becoming red 

 spotted ; the stem is solid, white, stained with red dots or squamules at the 

 apex. 



The cap is 3 to 5 inches broad ; the stem is 1 to 3 inches long and one-half 

 to three-fourths inch thick.

Figure 22. — Tricholoma personatum. (Edible) 



This species is to be found in mixed woods and on hilly slopes from August 

 until after frost. It may occur solitary, but often is found in patches. It is 

 edible and reported of fine flavor. 



There is frequently a sharp line of demarcation that appears like a well- 

 defined encircling ridge between the gills and the upper part of the stem. 



COLLYBIA 



In the genus Collybia the volva and the veil are both absent. The 

 margin of the cap is at first involute and the gills adnate, adnexed, 

 and never decurrent- the stem is of different substance from the 

 cap, fibrous or fistulose, cartilaginous or with a cartilaginous bark. 



COLLYBIA RADICATA. ROOTED COLLYBIA. (EDIBLE) 



(Fig. 23) 



In the rooted Collybia the cap is convex to nearly plane, distinctly umbonate, 

 often wrinkled, especially near the umbo, grayish brown or almost white, 

 glutinous when moist, margin incurved when young, sometimes upturned when 

 mature; the flesh is thin, white; the gills are white, broad, ventricose, dis-
