NATURAL HISTORY SURVEY 81 



On the ground in open woods. Winfield. September. Mr. 

 Massee, in Monograph Inocybe, Ann. Bot. 18: 489, states .that 

 this is a synonym of /. calospora QueL, the cystidia and spores 

 being identical. Our specimens agree with Professor Peck's de- 

 scription as given above, but differ from the description and figure 

 of /. calospora (Bres. Fung. Trid. I: 19, tab. 21) in having the 

 pileus wholly fibrillose-squamulose, and the stem flexuous and 

 pruinose throughout. Prof. Peck notes that the dried shriveled 

 stems resume their fresh plump condition when soaked in 

 water, a character well shown in our plants. 



Inocybe rimosa Bull. 



Pileus yellowish, varying rufescent and date-brown, fleshy, 

 conic-campanulate then flattened, at length reflexed, umbonate, 

 somewhat fibrillose, longitudinally cracked, disk even or cracked; 

 flesh firm, white. 



Lamellae very much attenuated behind, free or slightly ad- 

 nexed, somewhat ventricose, whitish becoming fuscous, at length 

 ferruginous, edge serrulated, pallid. 



Stem solid, firm, longitudinally fibrous within, occasionally 

 bulbous, mealy upwards, becoming yellow or fuscous. 



Pileus 2.5 to 5 cm. broad; stem 5 to 7.5 cm. long, 6 to 8 mm. 

 thick. Spores ellipsoid, even, 10 to 14 x 5 to 8 /u. Odor earthy. 

 Subgregarious. 



The plant so referred is our most common species, being found 

 under trees and in grassy places in open woods during late summer 

 and autumn; usually gregarious. The lamellae, however, are 

 broadly emarginate, and, while slightly attached, are decurrent- 

 toothed; otherwise the species agrees well with the above descrip- 

 tion and with Cooke's figure, Ill'st. pi. 384. The bulb, which is 

 flattened above, is found only in large specimens. The stem, 

 though tough elsewhere, is fragile at the very base, and unless 

 the plants are taken up carefully the bulb may be left in the 

 ground unnoticed. 



HEBELOMA. 



Partial veil fibrillose or wanting; stem fleshy, fibrous, clothed 

 somewhat mealy at the apex; margin of the pileus at first incurved; 

 lamellae sinuate-adnate, the edge more or less of a different color, 

 whitish; cuticle of the pileus continuous, smooth, somewhat 

 viscid. 



Spores somewhat clay-colored. Growing on the ground. 

 Lamellae rounded-adnexed, stem at length 



hollow H. crustiliniforme. 



Lamellae strongly emarginate, stem solid H . fastibile. 



Hebeloma crustilinifonne Bull. 



Pileus pale whitish-tan, pale yellowish or brick-color at the 

 disk, fleshy, convex-plane, obtuse or slightly gibbous with an 

 obtuse umbo, somewhat repand, even, smooth, at first slightly 

 viscid.
