332 THE AGARICACEAE OF MICHIGAN 



spores are similar, 15-18 x 6-8 micr., larger than given by Peck. The 

 dried type specimens indicate that they are closely allied, and that 

 one is a variety of the other. 



Cortinarius elatior pallidijolius Pk. is also probably a variety of 

 C. muscigenus Pk. The spores are the same, 15-17.5x7.5-9 micr., 

 but the stem is tinged with lilac. Both varieties have a shorter stem 

 ilian ('. muscigenus, and the caps are said to be pale fuscous, al- 

 though in the dried specimens they have the same shining, tawny- 

 tan color as in that species. The last variety is described and fig- 

 ured in N. Y. Mus. Eep. 51, 1901.

•1' ILEUS 5-10 cm. broad, firm, convex becoming nearly plane, 

 concave by the elevation of the margin, viscid when moist, yellowish- 

 brown, generally a little paler on the rather definite and commonly 

 fibrillose margin. FLESH whitish. GILLS thin, close, rather 

 luoad, adnate, creamy-yellow when young, soon cinnamon. STEM 

 7-15 cm. long, 8-12 mm. thick, elongated, equal or slightly thickened 

 at (he base, solid, silkytibrillose, slightly viscid, whitish or pallid." 

 SPORES almond-shaped, slightly rough, 10-12.5x5-6 micr. 



"Low moist places in Woods. Bolton, New York. August. The 

 margin is separated from the rest by a definite line, is 6-12 mm. 

 broad and conspicuously fibrillose." The description is adopted 

 from that of Peck.

 Illustration: Plate LXV of this Report. 



1' ILEUS 3-7 cm. broad, hemispherical-convex then expanded- 

 plane, glabrous, even, with a thick gelatinous straw-yellow pellicle, 

 which is glutinous when moist. FLESH thin on margin, violaceous 

 <il first, soon pallid. GILLS violaceous at the very first, soon whitish 

 then cinnamon, adnate-subemarginate, close, rather broad. STEM 

 •""> Hi cm. long, 5-8 mm. thick, subclavate 'or tapering upward, equal 

 above, spongy-stuffed, glutinous when moist from the thin universal 

 veil, which on, drying leaves thin yellowish patches on the lower*
