372 THE AGARICACEAE OF MICHIGAN 



purple, color subpersisting, at length cinnamon-umber, tkickish, 

 edge entire. STEM stout, 5-10 cm. long (often of medium length) , 

 10-15 mm. thick, equal or slightly enlarged below, firm, solid, 

 sheathed by the distinct, appressed, dingy -white universal veil, 

 which terminates at or above the middle in an evanescent floccose- 

 fibrillose ring, sometimes only marked by the thin subannular 

 patches of this veil, apex violaceous or pale drab, whitish to drab 

 within. CORTINA white, rather copious. SPORES broadly 

 elliptical, distinctly rough-punctate, maturing slowly, 9-10.5 x 

 5-6.5 micr., rusty-umber in mass. BASIDIA 36-40x9, 4-spored. 

 ODOR slightly of humus. TASTE mild. 



Gregarious or subcaespitose. On the ground, among fallen 

 leaves, in frondose and mixed woods. September-October. Ann 

 Arbor, New Richmond. Rather frequent. 



Tli is species approaches G. pulchrifolius in possessing purple gills 

 which remind one of Glitocybe ochrapurpurea except that they are 

 not as bright as in that species. An examination of the type-speci- 

 mens of G. pulchrifolius showed that our plant is distinct. The 

 spores never come within the sizes of Peck's species, and the pileus 

 has no reddish shades. The dried plants are also different. In 

 spite of these things the two species are close together. Except 

 for its lack of the hygrophanous flesh, and the character of the 

 surface of the cap it also approaches G. impennis Fr. and G. torvus 

 iioMlis Pk. The universal veil is usually well-developed, but some- 

 times the remnants show only as thin patches on the mature stem. 

 The purplish color of the gills is retained to late maturity. The 

 spores mature slowly and the measurements must be made from 

 mature plants. It must not be mistaken for either G. torvus Fr. 

 nor ('. impennis Fr.
