which somewhat changes the appearance of the mushroom and 

 lessens its value for edible purposes.

Pileus convex to expanded, depressed at times with age, 

 gregarious, 4-8 cm. broad, 1-2 cm. thick; surface dry, tomentose 

 to floccose-squamulose, often rimose-areolate, variable in color, 

 usually some shade of red or purple, fading to brown ; margin 

 entire, fertile ; context yellowish-white to flavous, reddish beneath 

 the cuticle, usually changing slowly to greenish or bluish when 

 wounded, especially near the tubes, taste mild; tubes adnate, 

 convex in mass, slightly decurrent, becoming much depressed at 

 times with age, yellow or greenish-yellow, changing to greenish- 

 blue when wounded, mouths large, angular, irregular, 1-2 to a 

 mm. ; spores fusiform, smooth, olivaceous when fresh, fading 

 to pale-brownish, 11-13X4-5/^: stipe subcylindric, often con- 

 torted, tapering at the base, flavous above, red or streaked with 

 red below, longitudinally furrowed, glabrous or minutely scurfy, 

 solid, sometimes yellow within at the base, 3-8 cm. long, 0.3-1.5 

 cm. thick. 



This species is, in most localities, the most common and abun- 

 dant member of the family, being the first to appear on mossy 

 banks in early summer and continuing to fruit until late autumn. 

 It is usually rather small, with reddish cap and stem, and large, 

 yellow tubes, which turn blue when wounded. It is sometimes 

 difficult to secure specimens for the table on account of a whitish 

 mould which appears to be particularly prolific on this species.
