fairlv well shown by Cooke illl.. PI. 783), differing however in the 

 shape iif ilic stem and in color. Old dried specimens sometimes <li> 

 have the color shown by Cooke's figure, li was round frequently 

 in the region between Ann Arbor and Detroit, 



395. Cortinarius brevissimus Pk. 

 N. V. Slate Mns. Rep. H. L888. 



"PILEUS 1.5-2.5 tin. broad, convex, often irregular, at first 

 minutely silky, then glabrous, dingy-white in argillaceous. FLESH 

 whitish. GILLS adnexed, close, '// first pale violaceous then whitish 



to finnai i. STEM very short, L-1.5 cm. long, 6-8 mm. thick equal 



hollow, silky-fibrillose, white, pale violaceous within. SPORES 

 broadly elliptical, 6-7.5x5-6 micr. 



''Thin woods. Catskill Mountains. New fork. September. Re- 

 lated to C. brevipes Pk., bu1 smaller, with a hollow stem and shorter 

 spores." 



396. Cortinarius abidifolius Pk. 

 N. Y. State Mus. Rep. II. L888. 



"PILEUS 3-5 cm. broad, convex, subglabrous, whitish tinged with 

 yellow or pale ochraceous, the epidermis sometimes cracking and 

 forming scales. FLESH thin, whitish. GILLS adnate, emar- 

 ginate, subdistant, whitish at first, then cinnamon. STEM 5-8 cm. 

 long, 4-8 mm. thick, equal <>r slightly enlarged at base, solid, n-hit, 

 but variegated u'itli yellowish, fioccose scales below, Bilky-fibrillose 

 above Spores subglobose, 6-7.5 x 5-6 micr. 

 "Woods, ('atskill Mountains, New Fork. September." 

 Closely related to this, if qo1 the same, is a species occurring 

 about Ann Arbor. It differs mainly in its slightly Larger size and 



stouter stein; the shred like appressed scales of the stem are dingy, 



not yellowish and the spores are slightly Larger, subsphoeroid, 7 !t 

 micr. The cuticle of the pileus is composed of differentiated, 

 narrow, horizontal hyphae, subgelatinous, bul scarcely subviscid in 

 moist weather. Its dimensions are as follows: pileus 3-7 cm. broad, 

 stem 5-7 cm. Long, 5-12 nun. thick. Both forms differ from ('. ochro- 

 leucus Fr. in the stem being enlarged toward the base ami in the 

 scalelike remnants of a universal veil. It should probably be in- 

 cluded in the preceding section. It is possible that this is \;ir. | I'.
