CLASSIFICATION OF AGARICS 167 



elongated-ellipl ic, subacute at ends, Bmooth, CY8TIDIA abundant, 



ventricose ilask shaped. 



Gregarious. The variety is common in swampy or mossj wet 



places on rich soil, of cedar aii<l hemlock woods. It scarcely dill'ers 

 except in color from the typical form as described by Bresadola. 

 The wet. habitat easily accounts for the more slender stem. The 

 color, however, is constanl in young and old plants, or may become 



brownish on the cap. The typical form is less easily distinguished, 

 ami approaches /. trechispora, an angular-spored species. In fact, 

 Bresadola has pointed out that Patouillard's figure No. 547, and 

 Cooke's Plate 402 are illustrations of /. trechispora. June-Septem- 

 ber. In coniferous regions. Houghton, Bay Yjew, New Richmond. 



Section V. Viscidae. Pileus viscid, more or less silky when dry. 



*8pores angular-tubercular. 



493. Inocybe trechispora Berk.

Cooke, 111., PL 403 (PL 402 as I. scabclla). 



PILEUS 2-2.5 cm. broad, convex, expanded-umbonate, viscid, 



silky when dry, umbo tawny and naked, elsewhere tawny-ochraceous 

 and paler. GILLS sinuate-adnexed, moderately broad, ventricose, 



close, white then grayish brown, edge white -fimbriate. ST KM 2.. "»-."» 

 cm. long, 2-3 mm. thick, subequal, usually tapering upwards, mar- 

 ginate-bulbous at base, glabrous, apex pruinose, solid, white. 

 SPOKKS tubercular-angular, slightly longer than wide, irregular 

 iu outline, 6-8x4-6 micr. CTSTIDIA ventricose. flask-shaped, 50x 

 10-1 8 micr., apex crystallate and obtuse. 



Gregarious. On the ground, among debris, in conifer swamps. 

 Houghton, Bay View, New Richmond. August-September. Infre- 

 quent. 



A small species, known by its viscid pileus with shining, naked 

 and tawny umbo, by the rather abruptly marginate bulb of the 

 stem and. by the tuberculate spores. Our plant agrees with Berke- 

 ley's species in the spore character as given DJ Massee. Ricken has 

 applied the name to a plant with spores 14-15x0-7 micr.
