Lamellae rounded-adnexed, crowded, whitish then clay-color, 

 at length date-brown, distilling watery drops in wet weather. 



Stem stuffed then hollow, stout, somewhat bulbous, white, 

 naked, white-squamulose at the apex. 



Gregarious in a lawn. Wheaton. In plants that appeared 

 in August, the pileus was 2.5 to 5 cm. broad; in those occurring 

 in September and October it was much larger, up to 10 cm., 

 and often rimosely cracked when old. It has the odor of radish. 

 Spores ellipsoid, 10 to 12 x 5 to 6 p. 



Hebeloma fastibile Fr. 



Pileus yellowish, tan, or becoming pale, compactly fleshy, 

 convex-plane, obtuse, somewhat repand, even, smooth, the in- 

 volute margin pubescent. 



Lamellae remarkably emarginate, somewhat distant, rather 

 broad, dingy clay-color, edge whitish, distilling drops in rainy 

 weather. 



Stem solid, wholly fleshy-fibrous, often twisted, white-silky 

 and fibrillose, pallid, white-scaly upwards. 



Pileus 5 to 6.5 cm. broad; stem 5 to 6.5 cm. long, 12 mm. 

 thick. 



On the ground in shaded thicket, Glen Ellyn. September. 

 The stem in our plant is somewhat hollow, and the pileus whitish, 

 approaching the variety alba. Spores ochraceous clay-color, 

 9 to 10 x 6 to 7 /x,. 



FLAMMULA. 



Veil fibrillose or none; pileus fleshy, the margin at first in- 

 volute; lamellae decurrent or adnate without a sinus. Usually 

 growing on wood. Spores mostly pure ferruginous, occasionally 

 tawny-ochraceous or fuscous-ferruginous.

2. Pileus greenish-yellow or purplish F. polychroa.

Flammula sapinea Fr. (Plate IX, Fig. 2.) 



Pileus fleshy, compact, hemispherical or convex, becoming 

 expanded, obtuse, dry, slightly flocculose-squamulose when 

 young, often becoming rimose and paler with age, golden-tawny, 

 paler and shining on the margin; flesh yellowish, odor strong. 



Lamellae broad, close, adnate, becoming tawny-cinnamon. 



Stem short, often unequal or irregular, compressed and sul- 

 cate, stuffed or hollow, yellowish or pallid. 



Pileus 2.5 to 7.5 cm. broad; stem 2.5 to 5 cm. long, 6 to 10 mm. 

 thick. Spores ochraceous, 7.5 x 5 /x. 



On rotting pine logs, Millers, Ind., October. Stem usually 

 incurved from position.
