Tkicholoma 



Cap fleshy, convex, rarely umbonate or depressed ; stem central, 

 stout, externally longitudinally fibrous ; gills sinuate, often be- 

 coming spotted with rusty stains, white, yellow, or grey. 



All the species grow on the ground, and are usually large, flesh}^ 

 and robust. Certain species of Plcurotus somewhat resembling 

 Tricholoma are distinguished by growing on wood. Collyhia differs 

 in the smooth, polished, and not fibrous stem. Some are edible.
