 Tricholoma decorosum Pk. 



Decorous Teicholoma 



(N. Y. State Mus. Rep., 25, p. 73. Plate i, figs. 1-4.) 



Pileus firm, at first hemispherical, then convex or nearly plane, 

 adorned with numerous broionish subsquarrose tomentose scales, dull 

 ochraceous or tawny, flesh white ; lamellae close, rounded and slig-htly 

 emarginate behind, the edg-e subcrenulate ; stem solid, equal or 

 slightly tapering upward, white and smooth at the top, elsewhere 

 tomentose-squamulose and colored like the pileus ; spores broadly 

 elliptical, .0002 in. long. .00015 broad. 



Pileus 1 to 2 in. broad ; stem 2 to 4 in. long, 2 to 4 lines thick. 



Decaying trunks of trees. Catskill mountains and Allegany 

 county. September and October. 



A rare but beautiful species. It is often caespitose. It departs 

 from the character of the genus in growing on decayed wood. It 

 bears some resemblance to Clitocybe decora Fr., from which it 

 differs in color, in the character of the scales of the pileus and stem 

 and in the color of the flesh and lamellae. The true relationship of 

 that species may be regarded as yet unsettled. Fries at one time 

 lalaced it in Pleurotus at another in Clitocybe. Gillet has referred 

 it to Clitocybe, Quelet to Tricholoma, and Saccardo to Pleurotus. 

 But it seems to me that the American plant here described belongs 

 to the genus Tricholoma notwithstanding its unusual habitat. The 

 emarginate lamellae and the solid fleshy stem indicate it. 



Tricholoma rutilans Schoeff. 

 Eeddish Tricholoma 



(Hym. Europ., p. 53. Syl. Fung., Vol. V, p. 96.) 



Pileus fleshy, campanulate becoming plane, dry, at first covered 

 ivith a dark-red or purplish tomentum, then somewhat squamulose, 

 the margin thin, at first involute, flesh yellow ; lamellae crowded, 

 rounded, yelloiv, thickened and villose on the edge; stem somewhat 

 hollow, nearly equal or slightly thickened or bulbous at the base, 

 soft, pale-yellow variegated with red or purplish floccose squamules ; 

 spores .00025 to .0003 in. long, .00025 broad.
