440 THE AGARICACEAE OF MICHIGAN 



umbonate, glabrous, watery rusty-fulvous at first when moist and 

 striatulate on margin, soon honey-colored or alutaceous to paler 

 when dry, soon even, hygrophanous. FLESH thin, concolor. 

 GILLS adnate, sometimes emarginate, narrow, close to subdistant, 

 thin, pallid-brown then cinnamon, edge concolor. STEM 3-8 cm. 

 long, 2-5 mm. thick, tapering downward, thickened above, attenu- 

 ated at the slender curved base, flexuous, soon rigid, stuffed then 

 hollow, fulvous (moist) pallid or white and shining when dry, 

 scarcely fibrillose at the first by remains of the scanty white COR- 

 TINA. SPORES short-elliptical, almost smooth, 6-7.5 (rarely 8) 

 x 4-5 micr. BASIDIA 25-30 x 6-7 micr. ODOR none or slight. 



Solitary, scattered or subcaespitose in pairs. Among leaves and 

 humus in frondose and conifer woods. Ann Arbor, New Richmond. 

 September-October. Frequent in the late autumn. 



It is very variable in color, and the gills are sometimes rather 

 broad, while the spores are consistently small. The plants are 

 often the shape and color of C. obtusus Fr. as illustrated by vari- 

 ous authors, so that it seemed advisable to refer to these figures. 

 It seems that C. obtusus Fr., of which I obtained several collections 

 at Stockholm, differs mostly in its larger size, its quite broad gills 

 and larger spores; these measure 9-10x5.5-6.5 micr. It is to be 

 noted that the figures of Fries (Tcones, PI. 163, Fig. 1) of C. 

 scandens can scarcely be the form referred to in his descriptions. 

 In "Monographia" he says distinctly that the stem is "incrassate 

 at apex, always attenuate at the base," while in the figures the 

 stem is not attenuate. The colors of his figures also do not corre- 

 spond with the descriptions. I have followed the idea of the 

 description, as did Cooke, Rickeu, Britzelmavr and others. We 

 doubtless have forms of C. obtusus also, but they need further studv 

 Fries' unpublished plate of G. rigens Fr. shows that species to 

 differ from C. scandens in its larger, stouter habit and convex or 

 gibbous pileus; its gills are not broad.
