Pileus fleshy but thin, fragile, convex, becoming plane, sometimes 

 slightly depressed in the center, dry, silky fibrillose or fibrillose- 

 squamulose, grayish brown, darker or brown in the center, often 

 with yellowish or ferruginous stains, flesh white or whitish, not 

 changing color where wounded, taste and -odor almond; lamellae 

 thin, close, free, grayish, soon pinkish, finally brown ; stem equal or 

 slightly tapering upward, sometimes bulbous, stuffed or hollow, 

 slightly fibrillose, white, the annulus slight, often evanescent; spores 

 broadly elliptic or subglobose, .0002 of an inch long, .00016 broad. 



The specimens from which this species was first described were 

 smaller than others collected later. The caps in these now before 

 us are 1-3 inches broad and the stems 1-2 inches long and 3-5 lines 

 thick. The flesh is white and unchangeable when cut or wounded. 

 It has a taste resembling that of almonds which has given origin to 

 the local name " almond mushroom." One correspondent says that 

 " it is the finest flavored mushroom he has ever tasted." Bruises 

 of the cap and stem of the fresh plant sometimes assume a yellow 

 color. The plants grow singly or in clusters. They appear from 

 September to November, and have been found growing in both 

 sandy and clayey soil, and in tan yards. The range is from Michi- 

 gan to Massachusetts.

The frost boletus is a very showy species. Its deep red cap and 

 distinctly reticulate red stem are attractive to the eyes and a delight
