CLASSIFICATION OP AGARICS 181 



tinarius. The spores lose their pink color in the herbarium. Lux- 

 uriant specimens, with caps 15 cm. across, have been found, whose 

 surface was minutely silk) Qoccose. When fresh the plants present 

 ;i beautiful appearance because of their chalky whiteness of cap nnd 

 stem as contrasted with the deep flesh-colored gills. Ii is an ab 

 rant species and approaches the genus Entoloma.

"PILEUS 2.5-5 cm. broad, fleshy, Arm, convex becoming nearly 

 plane, or concave by the margin curving upward, glabrous, subviscid, 

 white or yellowish-white. FLESB white. <ilU.s thin, narrow, close, 

 sinuate, adnexed, whitish becoming brownish-ferruginous, STEM 

 3.5-7 cm. broad, 4-6 nun. thick, equal, Arm, rather long, solid or 

 stuffed, slightly mealy at the top, white. SPORES subellipsoid, 

 pointed at both ends. L2-16x6-8 micr." 



Specimens sent from Detroit have been referred by Peck to this 

 species. Its Large spores, narrow .uills ami white or almost white 

 cap distinguish it from related species. Compare //. albidulum, 

 II. si mill and //. sarcophyllum. 



508. Hebeloma colvini Pk. 

 N. V. State Mus. Rep. 28, 1876. 



"PILEUS 2-7.5 cm. broad, convex or nearly plane, sometit 

 gibbous or broadly umbonate, rarely centrally depressed, glabrous, 

 grayish or alutaceous with an ochraceous tint. GILLS close, broad. 

 sinuate, adnexed, whitish, becoming brownish-ochraceous. STEM 

 2-8 cm. long, 2-6 mm. thick, equal, flexuous, silkx fibrillose, Btuffed 

 or hollow above, solid tow aid the base, whitish. SPORES ellipsoid. 

 L0-12x5-6 micr. Sandy soil in open places. Tin- mycelium binds 

 the sand into a globose mass which adheres to the base of the Btem." 



The description is that of Peck. One collection at New Richmond 

 is closely related. The plants grew in sand which adhered to the 

 cap ami stem. Our plants varied from the type in having narrow 

 gills ami a solid stem which becomes cavernous.
