The plants grow gregariously or sometimes in tufts on the ground 

 under or near trees or in thin woods, specially of pine, or in mixed woods. 

 The caps vary from 1 to 4 inches in breadth, and the stems from 1 to 3 

 inches in length, and from 2 to 6 lines in thickness. The plants occur in 

 autumn. In Europe there is a variety of this species which also has a far- 

 inaceous odor, but it differs from our plant in having reddish edges to the 

 gills. It is called variety orirubens. 



One correspondent, in writing concerning the method of preparing this 

 mushroom for the table, says that, when steamed for 30 minutes, with the 

 addition of butter, pepper and salt, it makes a very good dish. 



Tricholoma portentosum centrale Pk. 

 Central Tricholoma 



PLATE 45, fig. 1-5 



Pileus convex, sometimes slightly umbonate, viscid, virgate with innate 

 blackish fibrils, sooty brown in the center, pale yellow or greenish yellow 

 elsewhere, flesh white ; lamellae moderately broad and close, emarginate, 

 white or yellowish ; stem equal, solid, white ; spores broadly elliptic, .0003 

 of an inch long, .0002 broad. 



This variety of the dingy tricholoma, T. portentosum, is well 

 marked by the colors of the cap, which is pale yellow or greenish yellow 

 except in the center, where it is sooty brown or blackish brown. Minute 

 brown or blackish lines or fibrils radiate from the center toward the margin. 

 When fresh or moist the surface of the cap is viscid. The flesh is white 

 and the taste mild. 



The gills are white or yellowish, rather broad and rounded at the end 

 next the stem, to which they are narrowly and slightly attached. Sometimes 

 they are transversely striated or streaked by lighter lines. The stem is 

 nearly equal in thickness in all its parts. It is solid and white or whitish 

 both externally and internally. The cap is from 1 to 3 inches broad ; the 

 stem 1.5 to 3 inches long, 3 to 5 lines thick. The plants are gregarious and 

 inhabit thin woods. They may be found in autumn. This is a fairly good 

 edible mushroom, but not superior in any respect to many others that are 

 more abundant. The typical form of the species, Tricholoma porten-
