432 THE AGARICACEAE OP MICHIGAN 



cla rate-bulbous then elongated, soft-spongy, stuffed, pallid and 

 streaked with silky white fibrils, becoming sordid, not eingulate. 

 CORTINA white. SPOKES elliptical, rather narrow, smooth, 

 variable in length, 6-8.5 (rarely 9) x 4-4.5 micr. BASIDIA 30 x 6-7 

 micr., 4-spored. ODOR and TASTE mild.. 



Gregarious or scattered in thick leaf-mould of hemlock, pine and 

 beech ravines. New Richmond. September-October. Infrequent. 



When young the pileus is firm and very silky on edge, 

 when old it becomes soft; the stem is early affected by grubs and 

 soon decays at the base. The color of the pileus changes markedly 

 and hence is very variable. Sections of very young buttons show 

 no universal veil.

 Illustration: Plate XC of this Report. 



PILEUS 5-10 cm. broad, hemispherical-convex at first, campanu- 

 late-expanded, obtuse or broadly unibonate, glabrous, hygrophanous,, 

 with a slight pellicle, watery cinnamon when moist, becoming brick- 

 color on drying, then paler, even, margin at first incurved and white- 

 silky. FLESH concolor then pallid, rather thin. GILLS adnate, 

 moderately broad, broadest behind, close, distinct, thin, at first 

 brownish-pallid then cinnamon-brown. STEM 4-8 cm. long-, 8-18 

 mm. thick, varying equal to subclavate below, rather stout and firm, 

 straight or curved at base, pallid or whitish, silky-fibrillose and 

 shining when dry, stuffed. CORTINA white. SPOKES elliptical, 

 6-8.5 x 4-5 micr., smooth. ODOR and TASTE slightly of radish. 



Gregarious. On ground in moist, low, frondose woods. Ann 

 Arbor. September-October. Infrequent. 



This species was originally referred to the subgenus Phlegmacium. 

 The pellicle of the pileus is, however, scarcely gelatinous although 

 the surface feels somewhat slippery. This and the reddish coloi 

 which appears on the pileus as it loses moisture are the most strik- 

 ing characters.
